We follow that old rule of conservation labs always being in the basement (though we do have a window!). Well, technically we’re not actually in the basement. While our lab space was originally storage space when the library was built, there is actually another storage space below us, i.e. the real basement. Or, more accurately, the deep, dark void full of stuff…random chairs, pieces of shelving units, leftover carpet tiles, etc. Recently we heard a lot of activity going on down there and when Holly made a little trip down to check out our PackTite she found the space completely different. Dare I say, verging on organized. And front and center was this little gem with a thick layer of dust on it… A little letterpress printing press!
Needless to say, Holly scooped that puppy up and whisked it away to the lab (and then promptly called our facilities manager to make sure that was ok)! We have every intention of fixing this beauty up and doing some very fun and exciting things with it in the future. So stay tuned! Jessica Ebert (UCL) – Conservation Technician
This past April, during one of the UCL Special Collections meetings, the Lab received a new stabilization/housing project; a collection of Latin poetry pamphlets translated into German from 1830-1917. This collection of 79 volumes is part of the Classics Library’s collection. While the Lab will be treating and housing all 79 volumes, the collection is being brought to the Lab in small, manageable batches. The first batch received by the Lab were pamphlets bd.66 to pamphlets bd.79.
After consulting with the Lab’s conservator, each pamphlet was evaluated and treated individually. The condition of each pamphlet greatly varied; some pamphlets were in good condition, with only small tears along the outer joints of the paper cover. Other pamphlets were in poor condition, with missing covers, detached covers, split textblocks, torn or missing covers.
After the first batch of pamphlets was evaluated and treated, four stabilization treatment types were established for future batches. According to the condition of the pamphlet, from good condition, fair condition, poor condition, to severe condition, each pamphlet received either no treatment, a minimal treatment, a minor treatment, a major treatment with stabilization though encapsulation, respectively. For future batches received by the Lab, the same treatments will be applied with small variations when needed. No treatment: For any pamphlets in good condition do not require treatment, these pamphlets will simply be surface cleaned and receive a polyester film jacket. Each image below shows an example of the treatments mentioned above. Click on the photo to view the full size image: Fair condition/ minimal treatment: This group of pamphlets were in fair condition. There were minor tears on the cover that were mended.
Poor condition/minor treatment: This pamphlet was in poor condition. The cover was torn and detached and the textblock was broken with loose gatherings. The cover was mended and the textblock was repaired. The cover was reattached to the textblock.
Severe condition/ Major treatment – stabilization through encapsulation: This pamphlet was received in severe condition. The covers were detached from the textblock and showed major losses. The textblock was stapled and the staples had corroded overtime which stained the paper. The staples were removed and the textblock was sewn. The covers were encapsulated and sewn onto the textblock using Usu Mino tissue hinges.
Once the treatment of the first batch of pamphlets was concluded, the pamphlets were housed together in a custom made corrugated clamshell box with a clear spine. This model of a modified corrugated clamshell box will be used for the future batches of these pamphlets that the lab receives from the Classics Library. Modified corrugated clamshell box with a clear spine. Modified corrugated clamshell box with a clear spine.
At the moment, I am working on the second batch of pamphlets; pamphlet bd. 50-bd. 65. On this second batch most pamphlets are in poor condition. The covers are detached and some pamphlets have missing covers. However, the textblocks are in good condition. Below you will find a sneak peak of this ongoing treatment. Pamphlets bd. 43 – 49 – small portion of the second batch of pamphlets received by the Lab.
The Ohio Preservation Council and the State Library of Ohio are pleased to offer a full day symposium in celebration of the book. This symposium will highlight the history and art of the book with panel discussions, concurrent talks, and hands-on learning.
Keynote speaker, Julia Miller, will discuss various topics including the urgency of historical book description and why conservation and preservation is everyone’s responsibility.
Book Artist, Macy Chadwick, Assistant Professor in Medieval Studies, Bonnie Mak, and Book Conservator Jim Reid Cunningham will speak about the future of the Codex in a post codex panel.
A curated set of breakout sessions will further the registrant’s knowledge and appreciation of the codex in a number of creative and historic applications. These sessions include a presentation by Kyle Holland from the Morgan Paper Conservatory, a dramatic history presented about the 1748 Ephrata Martyrs Mirror by Carrie Phillips, a discussion about the conservation and preservation of scrapbooks by conservators Jayme Jamison and Ashleigh Ferguson Schieszer, and a session with Julia Miller who will present her collection of bookbindings.
Additionally, attendees will have an opportunity to purchase one of a kind materials from local craftspeople, bookbinders and artisans at the exhibitor hall(way).

In my last “Fun with PhotoDoc” post I discussed the my recent RTI training with Cultural Heritage Imaging at Yale University. If you missed that post you can check it out here. In that post I discussed our first RTI capture session on a book entitled, Aller Bücher und Schrifften des thewren, seligen Mans Gottes Doct. Mart. Lutheri …, which is part UC’s Archives & Rare Books Library’s collection and is the eighth volume in an eight volume set. The binding is most likely age-hardened alum-tawed leather (though possibly vellum) on wooden boards with embossed paneled decoration that is barely visible under normal illumination. In that first RTI blog post I shared some snapshots of the various RTI modes you can explore within the RTI Viewer software, but I knew that I ultimately wanted to create a video capture of the RTI Viewer in action. I was finally able to do that using a free software called TinyTake.
Specular Enhancement Mode with color removed (HSH) – notice the “1571” inscription that becomes more apparent. This volume was printed in 1568, and we believe that 1571 was when the publication was bound.
Normals Visualization Mode (HSH) – allows the human eye to better determine is convex and concave on the surface of the cover.
Diffuse Gain Mode (PTM) – This mode is ideal for visualizing surface abrasions and losses. Take notice of the “ID” inscription that becomes more visible, and when we switch back to the default mode you can see that this “ID” inscription is virtually invisible to the naked eye.
I have to say, Catarina and I really enjoyed the capture process for this binding, but when we found that “ID” and then looked at the physical binding and could barely see anything…we were kind of giddy! I’m hoping to create more RTI Viewer video captures like this as we carry out more RTI capture sessions for collection materials. When I do, I will make sure to share them here.

At the beginning of April I was lucky enough to attend a RTI (Reflectance Transformation Imaging) workshop offered by Cultural Heritage Imaging (CHI) at Yale University. CHI is a non-profit organization that shares and teaches RTI and Photogrammetry technology with cultural heritage institutions around the world. The class I attended was a 4-day NEH grant sponsored course taught by three RTI experts from CHI, and it was amazing! This is a composite image of all the highlight points from one RTI section. The software uses these highlight points to map the surface shape and color of your object.
So, what is RTI? CHI describes it on their website as “a computational photographic method that captures a subject’s surface shape and color and enables the interactive re-lighting of the subject from any direction”. For highlight RTI, which is the least expensive and most accessible method for most institutions and what I was taught in the class, you basically take a series of 36 to 48 images of an object where everything is constant (settings and position of objects, camera and spheres) except for the light position. With a reflective black sphere (or 2) set up next to your object, you move you light source around the object at varying angles. Then, you take that set of images and plug them into the free RTI software provided by CHI and the algorithm detects the sphere(s) and the highlight points (from your light) captured on the sphere(s) and voila!…you have an fun and interactive way to look at your object’s surface texture.
Before I attended this fantastic training opportunity, our conservator and I knew right away what the subject of our first capture would be when I returned…a 16th century German Reformation text by Martin Luther with a highly decorated cover that is practically invisible under normal illumination.
Here’s a time lapse video of our first (and second) capture in the Lab…
That day (Tuesday) were were able to capture the upper and lower covers of the Reformation text (from ARB), the original silk cover from a 17th century Chinese manuscript (from Hebrew Union College) and an illuminated page from a German vellum prayer book (from PLCH). And here our some snapshots of our results from two of those captures (click on the thumbnails for a larger view of the image)…
This possibly 13th century German Prayer Book has a full stiff vellum binding and an illuminated first page. The varying modes highlight condition issues like worn/abraded parchment and flaking gold illumination, as well as the overall surface texture of the illumination.
I hope you’ve enjoyed getting a little sneak peek into RTI. I will be demoing and discussing in further depth this afternoon from 1:30 to 3pm at the Lab’s annual Preservation Week Open House. I also hope to do more RTI captures/processes in the future and share them here. Jessica Ebert (UCL) – Conservation Technician

The Preservation Lab had the opportunity to collaborate with our Director of Library Communications, Melissa Norris, and the Head of Archives and Rare Books Library, Kevin Grace, to create a hand bound writing notebook full of fun facts about the Library system. The book was bound by Jessica Ebert, conservation technician.
Also pictured is a custom bind of Dot Christenson’s book Keep On Fighting: The Life and Civil Rights Legacy of Marian A. Spencer, also bound by Jessica created to mark the gift of the Marian Spencer collection to the Archives and Rare Books Library.
The amazing enclosure made by our very own conservation technician, Chris Voynovich, for volume 1 of the W.S. Porter Collection.
We very recently returned a two volume collection of photographs taken by William S. Porter, known as the W.S. Porter Collection, to the Public Library. William S. Porter is known in Cincinnati as one of the two photographers responsible for the 1848 Cincinnati Panorama (you can read more about and even explore this amazing daguerreotype panorama here). Volume one of the collection consists of 7 cased photographs (including daguerreotypes, ambrotypes, and tintypes) and 1 non-cased tintype, all reportedly taken by W.S. Porter, while volume 2 consists of one framed daguerreotype of W.S. Porter and a preservation print of that photograph. When these photographs arrived in the Lab for treatment, many of the cases were damaged (especially along the spine – some broken completely, one previously “repaired” with tape, etc.), the framed photograph needed re-packaging, and the collection needed two custom enclosures (vol. 1 & 2) to safely store all the photographs. (Left) Before “bench” photos of one of the cased photographs labeled “John Wesley Lever”, (Right) After photos of the mended case.
Now, as anyone who does photographic documentation will tell you, taking treatment documentation photos of photographs is a pain, especially on the copy stand (i.e. from above) and especially when you were trained in-house in a book and paper lab. Glass objects just aren’t as common around these parts. During PhotoDoc glass just acts as a mirror, reflecting all your light and even your camera lens and obstructing the actual photograph you are trying to capture. But we knew that we wanted some good quality photos of the photographs to print as surrogates and to also use in the enclosures. Black foam core and an Olfa rotary cutter to the rescue! Using these two supplies I created a non-reflective black surface to place around the camera lens to help reduce reflections and absorb light. In order to mount this black foam core on the camera lens I measured the diameter of our lens and the distance from the edge of the lens to the neck of the copy stand when the camera was in place. The foam core allows enough flexibility for the deflector to just slide past the UV filter and snap into place securely.
With the black non-reflective board in place, I was able, with guidance from our conservator, to get some pretty good shots of the photographs to be used as surrogates. The photos were also printed out and attached to the back of individual tuxedo boxes for each cased photograph. Instructions to “store face down” were placed on the front of each tuxedo box to assist patrons in proper storage. (The glass on all of these photographs is degraded and if stored face up the glass can actually weep onto the photograph causing significant damage, therefore cased daguerreotypes/ambrotypes/tintypes are generally stored up-side-down to prevent further damage to the actual photograph). All of the tuxedo boxes for volume 1 were housed within a two-tiered clamshell box with two removable trays made by our resident “Box Master”, Chris Voynovich. It should be noted that it’s a miracle this enclosure made it out of the lab and back to the Public Library, because several staff members were so enamored with it and thought it would make the best jewelry box! I mean, it kind of would, wouldn’t it?
Here are the images I was able to obtain using my homemade non-reflective board:

Fun with VideoDoc: Lining a Oversized Map (Edition 3)
Before treatment photo, map with cloth lining.
A couple months ago the lab received an oversized map from the Public Library’s collection. The map is from 1863 and depicts the businesses of downtown Cincinnati at the time. The Public Library would like to digitize the map, however when it arrived in the lab it had a variety of creases, stains and losses. It was also previously lined with cloth. Conservator, Ashleigh, and Sr. Conservation Tech, Catarina, began the work of removing the map from the prior cloth lining, washing the detached sections of the map to assist in removing the prior cloth lining adhesive, and locally humidifying and flattening the creases and distortions in the paper (caused when the map was previously lined).
Next up, lining the map with kozo fiber tissue and a mixture of wheat starch paste and methyl cellulose. For this, Ashleigh and Catarina created a make-shift light table, since the Lab’s was not large enough and began piecing the sections of the map back together. I couldn’t not document this climactic part of the treatment, so I went a little crazy, threw my go-to documentation equipment out the window (i.e. our Nikon DSLR), grabbed my iPhone and made a little video to illustrate the process. I hope you enjoy it!
*Please note, portions of this video have been sped up to shorten the length of the video…Ashleigh and Catarina work quickly, but not THAT quickly! Jessica Ebert (UCL) – Conservation Technician
I’m back for another edition of “Fun with PhotoDoc”. If you missed the first edition you can check it out here. Originally I had planned for that to be a one-off post, but then I thought it might be fun to make this into more of a series, sharing interesting facets of photographic documentation (aka PhotoDoc) as they come up. Really, it just gives me an excuse to share all the things about PhotoDoc that I think are just plain cool and to make gifs out of treatment documentation photos, which is so much fun!
This time around I wanted to share some interesting before treatment photos of two War Bond posters from the Public Library of Cincinnati & Hamilton County’s collection. For both of these I photographed the posters using normal illumination and then used raking illumination to highlight tears, cockling and bends/breaks in the paper. With this War Bond poster the raking illumination really shows off that large tear that extends from the center to the bottom of the poster. Under normal illumination this substantial tear gets lost in the pattern of the female subject’s dress. Also, while the normal illumination allows for better visibility of the water damage in the bottom left hand corner, raking light better highlights the resulting cockling and distortion of the paper in that area. For this poster, raking light really highlights all the undulations and cockling that have been caused by the poster being partially adhered to a piece of board. You can also more clearly see the fairly large tear located under the word “Hun” under raking illumination versus under normal illumination. Jessica Ebert (UCL) – Conservation Technician
As a farewell gift and appreciation for all the work and time dedicated to the University of Cincinnati, The Preservation Lab was asked to create a custom binding for an Album for the Provost and 29th President Beverly J. Davenport. UC Government Relations and University Communications provided the lab with single sheets printed with photographs of Dr. Beverly J. Davenport during her time at the University of Cincinnati. To create the custom binding the single sheets had to be cut using one of our board shears. All the sheets were precisely cut to the same dimensions and a textblock was created. Once the textblock was ready, endsheets and pastedowns were selected. In this case since this book was dedicated to our Provost and 29th President, the color of the endsheets where the colors of UC, red and black. A white paper was chosen as a pastedown. Since the pages were single sheets, the finished book would need to have a simple structure: a double fan adhesive binding. This structure is perfect for a textblock of single sheets as it provides a strong binding that allows the text block to be opened almost flat without causing the pages to separate from each other and break free. The adhesive is pasted onto the spine of the text block with a double fanning technique, where the pages are fanned in both directions allowing the adhesive to reach about 1 mm into the text block pages. After the pages are fanned in both directions, the spine of the text block received a lining of Cambric Cloth to provide support and an attachment for the cover. The spine was also lined with a handmade paper further strengthen the spine and prevent it from breaking from heavy use. Once the textblock was finished, the cover was created, a cloth cover quarter binding. To continue with the theme of UC colors, a marbled paper with red and black tones was chosen. A black cloth was chosen for the spine lining. The album received striped red stuck- on endbands.
After the cover was made and the textblock was cased in and the album was ready to receive a title. The title was created using the Lab’s hot stamper. Several titles were made using the same black cloth used on the spine. A silver title stamped on a black cloth was chosen, since it best matched the theme and colors of the cover.
And the final result:
The Lab deeply appreciated this opportunity to contribute to the farewell gift and wish our 29th President Dr. Beverly J. Davenport all the best. Catarina Figueirinhas (UCL) — Senior Conservation Technician
