As many in conservation know, objects come to a library or archive in myriad ways and conditions. Boxes, trash bags, coffee stained, mold affected, falling apart, pristine. They must be quarantined, assessed, and then brought into conservation for treatment and housing. They may even have previous repairs, as in the case of this set of badly damaged lithographs that came to us wrapped in wax paper sleeves. They are part of the John Scott Beals Civil War Papers collection.

The Japanese paper backing on the verso of the prints. You can see the discolored adhesive through the paper.

As you can see, they had been lined on the back with Japanese paper adhered with some kind of discolored paste. A backing removal was necessary to remove the brittle mystery adhesive. As the backing was removed, pieces of the lithograph began to fall away in some areas. Their location was captured with my phone camera as I progressed through the removal.

Using magnification I examined the print to determine that it was a chalk lithograph, as identified by the chalky, grainy black lines. An examination of the color led me at first to believe it was a standard chromolithogaph, where the color was applied by several, separate stones. However, further examination of the pinkish straight lines in the sky and the cross-hatching on the ground leads me to believe the color may have been applied by several woodblocks. Alternately, the image below supports the chromolithography technique. Could there be both? My examination of the text ink revealed an different method of application as well. The text letters had sharp, defined borders, which signified relief printing. The nature of the mass production of these prints supports the need to be able to apply custom text to a standard image.

Mysteries still remained: What did the lithograph originally look like? What was its purpose? I knew this would guide my treatment of the object after the backings were removed, so I began my research. Eventually, a search on civil war lithographs led me to a blog post by archivist Nancy Sullivan from the Historical Society of Montgomery, PA. Here were similar looking works on a much larger scale. I lined up the detached parts of the lithograph and compared it to an example in the blog. Where the pieces met, the image became congruous. The course of treatment was now clear.

Nancy Sullivan went on to posit that the ovals on the lithograph may have sometimes been left blank for the family who purchased the item to attach a photograph. On our register, some of the ovals had printed portraits, and some had albumen photographs attached. Perhaps when the item was printed, the people filling each role were not yet assigned their role, or a portrait could not yet be drawn of them before the lithograph was made.

 

After the paper backing was removed mechanically with a scalpel, the separated pieces with lined up with the image side facing up. Tabs of solvent-reactivated Klucel-G coated tissue were used to hold the pieces together while the verso of the lithograph was repaired. Tears were mended with both untoned and toned Japanese tissue. Toned tissue repairs were made when the tears had minor losses. Fills were used for large losses.

Progress continues on the optical media project here in the Preservation Department. All discs in the University Lecture Series collection have been ripped and are now in the process of being permanently stored. If permissions allow, certain lectures will also be uploaded to the Special Collections’ YouTube channel.
Technically speaking, most of the time so far has been spent navigating the Ripstation, a combination hardware/software system designed to rip large number of optical discs. The collection includes more than 1000 discs, primarily formatted as CD-DA, DVD Video, or data discs. Each of these formats requires a slightly different approach to preservation, typically in the form of what software is used.

The majority of the discs recorded before 2010 were formatted as Compact Disc-Digital Audio (CD-DA). Because this is also the format most commercial CDs use, Ripstation’s proprietary software (also called Ripstation) was best-suited, as it is optimized for this sort of collection. Discs were ripped into two different formats for both preservation and access purposes. For preservation, the BWF 96khz/24bit format was selected for its lossless, uncompressed quality and its ability to embed desired metadata within the wrapper’s header, thus greatly reducing the chance of intellectual separation between content and metadata. For access, the .MP3 format was selected, because it is widely accepted and supported as an accessible audio format. In addition, of the available output formats, .MP3 can be most easily transcoded into an .MP4 file to upload to Special Collections’ YouTube access channel, with little risk for losing any data.

This transcoding for the access copies is handled by Adobe Media Encoder, as is uploading directly into the Lecture Series playlist. To match the access copies from the magnetic media, part of the Lecture Series collection that has already been uploaded, the desired output is an .MP4 with audio wrapped inside with a logo (YouTube only accepts video files). After upload, we apply closed captions to all files for accessibility.

For the DVD-Video carriers in the collection, the desired output (perhaps somewhat obviously) differs from the CD-DA carriers. After some experimentation with variants on a data validation workflow, our conclusion was that the optimal output for Special Collections’ purposes was an .ISO disc image, which can be mounted easily as an access copy for researchers.

As the project progressed, some discs we encountered were neither CD-DA nor DVD, but simply data discs onto which .MP3 or other media files had been “dragged and dropped.” These were ripped with the DataGrabber software, and their original file format was maintained.

What metadata Ripstation uses and where it draws them from varies by the software used, which itself varies by the format of optical disc being ripped. Ripstation’s primary software is the program of the same name, which is intended for CD-DA-formatted discs, typically commercial ones. For automatic metadata population, an internet connection is required, so Ripstation can scour private and open-source databases for the artist, album, track titles, and other relevant metadata per disc. Acquiring metadata this way would not be helpful to the project because of the singular and noncommercial nature of the content. Due to this constraint, as well as networking limitations, this particular Ripstation was left offline.

So from where could the software draw its metadata? Ripstation has accounted for this possibility in the design of the User Data feature. Typically, the names of ripped files could be an assigned structure of metadata that would look something like %D_%A_%Y . Each letter corresponds to an established metadata category, so files named according to this structure will look like “[AlbumName]_[AlbumArtistName]_[AlbumDate]”. This system also allows for user-input metadata, in the form of a .TXT file in the program folder. The User Data system, which allows up to 10 user-defined metadata categories (%0 – %9) and can be used with all Ripstation software, is what we used for this project.

Each disc file was named according to its AV number and container number, according to the information available in the masterlist. For later discs with no container number available, that value was substituted with the date of recording. Batches were named with the reference number of the collection, the container number of the first disc, the container number of the last disc, and (if CD-DA or DVD) the disc type.

Now that all 1000 discs have been ripped, the next phase is twofold: 1. Documenting the project (of which this blog post is a part) and 2. For the lectures without permissions restrictions, encoding and uploading to the Special Collection’s YouTube Channel. This process has already begun, with over 5000 minutes of audio made publicly available so far.

History and background

The term “underground comix” defines a style of small press or self-published comic books produced outside of the mainstream styles. The Underground Comix Collection in Iowa State University Library’s Special Collections includes over 1,500 printed comics, hand-drawn sketches and related materials ranging from 1947 to 1995. Rare Books and Manuscripts Archivist Amy Bishop notes that while many of the pieces in the collection made their way to the university library in the 1970’s and the 1980’s, records indicate that there are some comics in the collection from as recently as 2007.

In the 1960s and 1970s, the artists who worked in this style created comics that discussed controversial topics and mocked conventional society. Their work explored mature themes like drug and alcohol use, sexuality, violence, feminism, anti-abortion and anti-war sentiments, Black Power, and LGBTQ+ issues. In doing so, the artists and the publishing companies did not adhere to the Comics Code Authority (CCA), which was introduced in 1954 and was intended to censor comic book content. At one time, Underground Comix were banned books.

As an aside: While doing a little online research, I came across an interesting blog post on this subject. It was published by The Robert E. Kennedy Library of Cal Poly State University on their Special Collections blog. You could take a brief detour and read it: “Understanding Underground Comix: An Introduction to the Moore Collection.

People

Many artists published with Underground Comix instead of a larger company because it gave them the opportunity to present their work with less censorship of the X-rated content. Underground Comix greats included cult figures like Robert Crumb, Gilbert Shelton, Richard Eugene “Grass” Green, Denis Kitchen and Trina Robbins.

You may be surprised to learn that popular TV shows like Teenage Mutant Ninja Turtles, Johnny Quest, and Space Ghost drew their first breath as underground comix. In fact, Trina Robbins, a female artist who published with Underground Comix, was the first to draw Wonder Woman. Richard “Grass” Green was the first African American comix creator to participate in the movement.

ISU Library Special Collections also holds a related collection of Clay Geerdes photographs (MS 0630). Clay Geerdes took numerous photos of Underground Comix artists and of their work. Geerdes’ photographs have appeared in many publications and were published as a book, “The Underground Comix Family Album“, in 1998.

Conservation treatment

The library’s collection of 3-dimensional artifacts contains a few dozen buttons from the early 1970’s. The buttons feature some of the iconic characters from Underground Comix. Assistant conservator Cynthia Kapteyn and I have recently run into a box of these buttons in the process of doing a comprehensive survey of the library’s artifact collection.

Recently we have been seeing lots of Comix at the Preservation lab, both printed issues and artist sketches.

The printed issues were from the 1950s, published by E.C. Comics. Many of the covers and pages had become torn and creased over time. Chunks of brittle paper have been lost, since these prime examples of ephemera were printed on low quality wood pulp paper and were not made to stand up to time and the relentless deterioration mechanisms of oxidation in cellulose. Mindy Moeller, Senior Conservation Technician, has repaired hundreds of pages using light weight Japanese tissue, pre-coated with a mixture of wheat starch paste and methyl cellulose and activated with a light application of de-ionized water.

Mends and fills made with pre-coated Japanese tissue are visible around the edges of the back cover.

One of the oversized boxes within the collection holds a number of drawings by an unknown artist associated with Underground Comix. The sketches were taped together with masking tape. The adhesive from the tape has started to penetrate through the paper, giving the paper a translucent oily quality and causing the sketches to stick together.

Using a micro-spatula, Sonya is lifting the edge of a small “speech bubble” fragment, taped over a previous version.

The artist had gone through a fascinating editing process, while creating their story line. If the artist was dissatisfied with a given cell or a speech bubble, they would rework the image or text on a fragment of paper and tape the new fragment over the segment they did not like. The artist used small loops of masking tape to stick down the fragments, so that the tape would not be visible past the edges of the stuck-on fragment. But over time the adhesive from the tape had leeched into the paper, making the tape underneath show through.

Left: A smaller fragment of paper is attached to the larger sketch with loops of masking tape. Right: Masking tape is lifted and a previous iteration of the sketch is revealed under the small fragment.

Masking tape was removed from the sketches and adhesive residue was reduced as much as possible. Mends of Japanese tissue were used to hold the sketches together in place of tape.

A heated spatula is used to remove fragments of masking tape from the reverse side. A Japanese tissue mend runs along the mid-line of the sketch (note the faint white tint).

The artist’s “edits” were reattached to the sketches using small hidden hinges made from Japanese tissue, using wheat starch paste. The sketches look and function in much the same way as they did before the conservation treatment. But the damaging tape adhesive has been removed, so it will no longer contribute to deterioration of the paper.

Other mentions

In the past, the Underground Comix Collection has been mentioned, exhibited and written about by other people on campus too. The Special Collections and University Archives blog, Cardinal Tales, has featured the Underground Comix Collection in 2015 in a post titled “Not Your Ordinary Comic Books”. The staff at Special Collections has used some rather spooky Underground Comix titles for the library’s Halloween Pop-Up Exhibit.

The Special Collections department featured Underground Comix in their Halloween pop-up exhibit in 2017.

The ISU Daily student newspaper had published the article “Underground Comix Have Rich History” in 2013. Student writer Victoria Emery had interviewed ISU College of Design professor John Cunnally about his scholarship related to the collection.

This is my humble homage to the candid and unapologetic art of Underground Comix artists. The image on the left is part of the cover of “The R. Crumb Handbook”, by R. Crumb and P. Poplaski, 2005.

Video_Preservation_Rack_1

A Common Video Preservation Scenario: A researcher requests a copy of a show held in your special collections. It’s a university production from the 1970s, a unique recording on ¾” tape. This tape is an “at-risk” item, because the inherent vulnerabilities of magnetic based media. What do you do? Do you send it out to a vendor, or do you digitize the tape in-house? Where possible, it’s best to digitize at-risk items in-house. It’s faster, it’s more economical over the long-term, and you can maintain your own quality-control standards.

AV preservationists have spent un-countable hours of our lives discussing the best capture format for analog video preservation. But actually… how you send the signal from the deck to the computer’s capture card is the most important aspect of digitizing analog video. You can capture 10-bit 4:2:2 anything, but the quality of what you’re capturing is linked to the signal you’re sending. So with this fact in mind, this post will describe the necessary equipment and guide you through the basic setup required for digitizing your at-risk analog video in-house.

One of the biggest issues that defines magnetic media as “at-risk” is obsolescence. It’s quite difficult to find and maintain the device needed for analog video playback. Prepare to spend some time digging around online or contacting potential dealers to find a functioning playback device. A good place to start looking for old, obsolete AV equipment is the on-campus video production house. They might have old gear hanging around! Or a local television station may have gear to donate to your archives. Be creative. You need well-maintained, industry-grade equipment with as much related documentation as possible. Those dog-eared operational and service manuals are invaluable for maintaining the functionality of old gear.

Cable - 3

RG-59/U 75 Ohms Broadcast BNC Video Cable

Using correct cables and cabling may be the single most important aspect to setting up a video preservation rack. Know your source signal (composite, component, or Y/C ) and send it out using only the highest-grade shielded cable. Remember: Shielding reduces electrical noise and…its impact on signals and…lowers electromagnetic radiation. Shielding prevents cross-talk between cables… Shielding not only protects cable but… machinery and people as well. [1] http://www.wireandcabletips.com/importance-shielding-cabling/

PRO-TIPS: Cables, Cabling, and Termination
• ALWAYS use broadcast-quality RG59 BNC 75ohm cables for video
• ALWAYS prefer XLR (balanced audio) cables to RCA (unbalanced audio) cables
• ALWAYS terminate open loops with 75ohm terminators at end of signal loops*

*But be careful! Improper termination can affect the video signal. A double termination can cut the video signal in half, while a lack of termination will overload the video signal. This might be where you need professional help.

CONGRATULATIONS!! You have managed to acquire a professional-grade BVU U-matic deck that supports machine control input. Now you are able to control the deck from a computer via a RS-422 cable, not missing any information at the beginning of the tape. This is good. This is why the RS-422 cable is included on the equipment list.

RS-422 - 2

RS-422 cable for Remote Control

Now what about the capture card and computer? I like the AJA KONA LHi capture card and AJA KONA KLHi-Box. Together, these will allow for seamless capture of composite, component, and Y/C (for analog signals) and SDI or HDMI (for digital signals). The KONA LHi works well with Premiere CS6, but it also has its own software that captures SD analog video as 10-bit 4:2:2 uncompressed v210. The Kona LHi is also able to capture closed captioning and timecode information. All of these are required metadata for video preservation. The preservation master could have up to five streams of data per file: a video stream, two audio streams, timecode, and closed captioning CEA-608. With newer computers, you’ll have to place the AJA Kona Li capture card in a thunderbolt expansion case and send the digital video signal from the expansion case to computer‘s thunderbolt in.

Now. It’s very important to place a Time Base Corrector between the deck and the capture card. You also need waveform and vector scope connected post-TBC, so you can monitor and adjust the video signal, using the scopes as your measurement tools. For example, if color bars are in front of the program, you can adjust the luma, chroma, black (set up), and hue (NTSC only) levels to get the best possible signal from the tape. Also, I recommend having all equipment ‘genlocked’ to the same reference to ensure picture stability. For SD composite video, it’s called blackburst – a composite signal of black with no picture data. With all pieces of equipment timed and in-sync, or locked to master sync, you increase the stability of your capture.

My preference for signal monitoring is viewing the signal directly off the deck, as well as post capture card. This helps pinpoint where any problems might occur in the signal. For example, if there is visible signal error on the monitor connected at the end of the chain (post capture), but the video looks good coming straight out of the deck, you can focus your troubleshooting on the cables, settings, and equipment either at or after the TBC point. It’s also important to have a cathode ray tube (CRT) monitor in order to view the video signal as it was originally intended. AND it’s best to have a CRT with blue-only, underscan, and H-V delay features. ‘Blue only’ allows you to calibrate your reference monitor with color bars and monitor your VTR noise. ‘Underscan’ allows you to see every scan line in the video signal, and ‘H-V delay’ allows you to check vertical and horizontal sync. These features will help you get the best signal out of your deck and troubleshoot any signal errors.

This brings me to the last piece of gear to install in your AV Rack: a test pattern generator. A test generator helps you check proper signal flow by sending a test pattern, like color bars, through the signal path. You can also use the color bar test pattern to set display levels – like brightness – and contrast to ensure your monitor is properly calibrated.

My two short months as the 2017 Lennox intern in the preservation lab have quickly come to an end! Even though it feels like I just started yesterday, I have had the opportunity to participate in so many projects in the lab which allowed me to stretch myself and exercise skills in many different areas. Here are a couple of the highlights:

One of my treatment projects was working on two WWI photographs with major losses.

For reference I used Victoria Binder’s article in Topics in Photographic Preservation entitled ‘Digital Fills for Photographs with Glossy Surfaces’

Ex-servicemen working on engines, before and after treatmentThese two silver gelatin photographs showing ISU’s part in post-war rehabilitation of WWI veterans were selected as part of a group of objects which will be shown in an upcoming exhibit by Special Collections/University Archives. Since the photographs will be on display, the large losses to the image area were determined to be distracting for the overall interpretation. I used Adobe Photoshop and a digital image of the photograph to create a fill for each loss that matched the surrounding image area.

Beekeeping, before and after treatment

Each fill was then printed out on glossy photo paper, which gave it a shiny finish that matched the original photograph nearly perfectly, a feature that is very difficult to reproduce manually with traditional materials. Another great feature of creating fills this way is that the color and exposure can be manipulated quickly and easily to match the original photograph exactly, cutting out a lengthy inpainting and color-matching process. One thing to be careful of while making digital fills, which was discussed at length with the curator beforehand, is that the recreation of lost information can easily go too far, verging on suggesting imagery that may not have existed. Therefore, the fills are very nondescript, focusing on light-dark contrast and overall texture instead of completion of objects or figures.

Another great blog post, “Digital Fills to the Rescue” by Rachel Pennimen, can be found on Duke University Libraries blog Preservation Underground.

Throughout my time here Sonya was working on updating the library-wide disaster response and recovery plan. These plans are a crucial part of the institutional planning, and can help significantly reduce response time and overall damage to the collections in the case of an emergency such as a flood or fire. I helped with the updating process by making sure vendor contact information was current, filling in missing sections, and sifting through extant and potential format options to pull useful information and organization ideas and put them together into a streamlined, yet thorough, plan.

Sonya and archivist Laura Sullivan recording information about priority collections in the stacks

One step toward a helpful disaster plan is identifying collection priorities, both in terms of value and sensitivity. To this end, Sonya and I did walkthroughs of Special Collections stacks with the curators to pick out certain items or collections that were especially important to the University. Knowing this information and the inherent sensitivity of the materials in the stacks can help pinpoint objects that should be salvaged first in the event of an emergency. This project taught me a lot about how disaster plans are actually built and are meant to function within a large institution like ISU Library.

My time at ISU was  busy! But I am so happy with all that I learned and accomplished over these two months, and know I will put that experience to good use in my upcoming projects!

One of the items that was used for the current Special Collections and University Archives ISU Pammel Court exhibit (designed by the History 481x class) is this little book. For the exhibit they wanted to show both the cover and one of the interior pages displayed as one piece.

With a quick sketch I came up with this:

jw2

 

I then had to think about how to hold the book up so it didn’t slide off the display wedge.

jw3

 

And then I had to figure out the dimensions….hmmmm…..

I drew out the 45 degree template and put the spine of the book along the diagonal. I went up about ¾ of the way and dropped a line down to the base. That gave me the measurements for the angled front piece, the back and the base.

jw4

 

I extended the base measurement out to make the lip that holds the book.

jw5

 

Then transferred all those measurements to a scrap piece of scrap board. Base, front, back, base with extension, face for book stop wedge, the piece the book will rest against, and the inner base to tape down.

jw6

 

I took those measurements and laid them out on the mat board and scored the lines about ¾ of the way through on what will be the bottom side of the base and added a piece of double stick tape to hold the book stop and inner base to the larger base.

jw7

 

And removed the little bit that wasn’t needed.

jw8

 

Double stick tape was used to hold the lip and the bottom pieces of the book support together after the book stop had already been folded and taped down.

This is what the final piece looked like from the side…

and from the front with a copy of the selected page.

About a month ago, the Preservation Lab hosted a group of students taking an upper level class in Public History. In this course the students use archival materials as primary sources for the research they are conducting, drawing from the Library’s Special Collections and Archives. Spending time in the Preservation Lab gives them a behind the scenes look at what it takes to stabilize  original materials so that they can be viewed in the reading room.

img_1085

As part of a practical  introduction to preservation, I demonstrated some hands-on conservation techniques that are often used to repair archival documents. Working on a discarded photoreproduction of Marston Hall, I removed some tape with a heated spatula and mended tears using wheat starch paste and Japanese tissue.

An interesting inter-disciplinary discussion happened around a group of WWII propaganda posters that were in the lab for conservation treatment. The posters were approximately 2 feet by 3 feet. They were staple-bound into a pad that was attached to a foldable easel made of cardboard.

rs16_3_57_bt_r   rs16_3_57_bt_v

The instructor and the students talked about the use of this object as a presentation tool, a 1940’s PowerPoint presentation of sorts. The speaker could take the easel-pad  along with them to give encouraging talks to the public about wartime efforts at home. As you can see from the photos above, the top poster had gotten torn and became detached from the pad.  If I were to take this object out of its historical context and to consider only its physical characteristics, I would want to take it apart, repair it and store all the components separately. The posters would go into one folder, while the easel and the staple binding would go into a different folder. Stored in this way, the posters would be safe and easy for scholars to handle  without the assistance of an archivist or a conservator.

img_1083

However, the research value of this presentation pad lies in its format, which tells the story of its use as a WWII propaganda tool. So, my approach will be to disassemble the structure, repair the components and then to reassemble the binding using thread loops in place of the damaging rusty staples. The binding will be recreated, but slightly altered  to provide more stability and longevity to the object, ensuring the preservation of both its physical self and its contextual meaning.

This class discussion brought home to me the point that historians and conservators have an important conversation to carry out. In order to adequately preserve historic collections, we need to share our distinct areas of knowledge with each other, enriching each other’s understanding of primary source materials.
