Preservation and Exhibition: DAAP Library’s Teaching Collection & Upcoming Gallery Talk (12/5)

For the past six months, Jessica and Catarina have been working with the DAAP Library on housing their Teaching art collection, including prior acquisition and newly acquired items.  This collection consists of different art prints on paper, print plates and manuscript parchment leaves in need of long-term housing. In addition to housing, this collection is used for teaching in a classroom setting and for exhibition.

Most of the collection only requires simple matting systems, but some require more intricate matting systems such as the copper plate along with its print, a project mentioned in a previous blog post entitled How many magnets is too many magnets!?.

As some of the items of this collection were being prepared to go on exhibit, we had the opportunity to create mounts for other items, such as two parchment scrolls that were included in the exhibit. This was a fun project to work on, as it required us to create a support that would secure both scrolls, while providing an elegant solution for display.

To start, Jessica created a very rough small model with mat board, polyethylene strapping, and paper (as we always do with anything new in the lab, we do love model making!!). The model provided us the visual example that we needed to create the mount for the two scrolls.

With the model in mind, we were able to engineer a good system that would provide support for the scrolls and could be used for display. The scrolls were supported with foam rolls on the inside for the rolled ends, and secured with polyethylene strapping that only touched the foam. The sections of the scrolls that were going to be displayed were also secured with polyethylene strapping that wrapped around the mat board support through slits in the board. At the bottom, the mat board extended outwards creating a small shelf to support the end of the scroll.

A small “shelf” of mat board supports the bottom of the scrolls.

As a result of all the mounting and matting we did for the Teaching Art collection and for the scrolls, each item is currently on display at the DAAP Library entrance case:

How many magnets is too many magnets?!

Recently Jessica and I started working on a series of special collection items from UC Libraries’ DAAP Library. These were recent acquisitions specifically bought to be used as a teaching collection within the DAAP Library. Most items are small prints and single manuscript leaves that need to be matted for exhibition and prepared for handling during class. We have been working on these in small batches since it is a much larger collection that keeps growing.

Most of the items we have received so far have been very straightforward matting projects, however we encountered one that was puzzling and fun to work on. We received this item: a proof print accompanied by its very heavy, copper engraving plate. The print was adhered to a paper brown envelope with no information and the copper plate was also unhoused.

The curator of the collection wanted both items to be housed together and housed in a way that would allow students to touch the items, and also be able to use them for exhibits.  We decided that both items would be matted individually, and then housed together in a thin corrugated clamshell box. The most challenging part would be to create a matting system that was strong enough to secure the very heavy copper plate and elegant enough to be used for exhibition.

The print itself received minor treatment, with the backing envelope being removed and the print housed in a polyester L-sleeve mounted with photo corners.

With the engraving plate, I needed to figure out how to create a matting system that was strong enough to hold the copper plate in place, especially if used for an exhibit where it may be propped at a slight angle. After considering some options, I created a sink mat that would secure the plate halfway, and then the rest of the sink mat would be adhered to the window mat so the copper plate, resting on a polyester tray, could be pulled out of the mat easily. How would I keep the matting system closed? ….with magnets, lots of magnets! For this project I used 24 rare earth magnets.

This was a fun project to work on. After using 24 magnets and breaking a few in the process, the copper plate was securely housed in the sink mat, while also able to be propped up for exhibition and handled for teaching.

Working with Abe

I love matting projects! Matting is an elegant way to present images and documentation for exhibition. We received a collection of letters and images from Abraham Lincoln in the lab from the Cincinnati and Hamilton County Public Library (CHPL) for preservation and conservation. After our conservator Ashleigh Schieszer completed the preliminary work of removing the artifacts from all the acidic and harmful elements they were previously in contact with, we collaborated on the matting choices. One cool thing I just love about this job is the opportunity to make tiny models of our intended work. Obviously, we can iron out some of the bugs and problem solve unforeseen obstacles with models, but making a tiny representation of my work is not only great to have as a future reference but is just really cool.

So, for one of the previously matted compilations the curator suggested retaining the beautiful custom mat for the finished system. This presented a problem because of the acidity in the original mat. The solution we came up with was to create an archival buffer mat between the original mat and the artifacts. Easy-peezy.

To mount overlapping objects, we decided to secure them to different mat board layers.  For example, the document on top will be attached to the back of the archival buffer with a polyester sling while the letter and portrait will be mounted to the backing board with edge strips or photo corners.

The archival buffer mat is hinged below the opened original mat.

We also added a custom portfolio for transportation and long term housing.

Exhibition Prep for Upcoming Show: Real Art for Young Artists

Join us September 15th, 2019 at 2pm as the Public Library of Cincinnati and Hamilton County unveils the newly acquired pen and India ink illustrations from Rosemary Well’s Noisy Nora in the beloved nook in the Children’s Library.  The illustrations are richly hand colored in watercolor, colored pencils, acrylic ink and gauche pigments.  With so much detail, they are a treat to see in person!
Acclaimed author and illustrator, Rosemary Wells, has written many endearing children’s books, including Noisy Nora (a story about a mischievous young mouse) and an entire series about the bunnies Max and Ruby.  As part of Ms. Well’s initiative, Real Art for Young Artists, Rosemary Wells has generously offered the Public Library of Cincinnati and Hamilton County the opportunity to exhibit more than a dozen original drawings for long-term display in the Children’s Library located in the Main building downtown.

Since the spring of 2018, the Preservation Lab has been collaborating with colleagues in the Public Library’s Programming, Digital Services, Cataloging, and Facilities departments, as well as the artist herself, on an exhibition of Wells’ Noisy Nora illustrations.  To prepare the materials for long-term exhibition each department lent their expertise to ensure a balance between preservation standards, viewer’s needs, and the artist’s vision.   This blog post highlights some behind the scenes activities leading up to the exhibition.

Above is an image of the nook in the Children’s Library selected as the exhibition space for the illustrations.  The nook is a perfect spot where the light can be controlled, preventing the artwork from fading overtime and it’s a great place to showcase the art at a height children can easily interact.  Facilities updated the nook with new paint and wall decals where the artwork will be hung.  In addition, to inspire young generations to create their own artwork, seating and tables for crafts will replace the current audio visual shelving and television.

At the Lab, approximately 16 pen and ink drawings and one booklet were received directly from the artist as a group within a folder. Many drawings were attached to illustration boards with translucent overlays wrapped around from behind, taped into place, giving the feeling as though they were just recently mocked up for production.    Graphite notes to publishers were written on the transparent papers to inform the size the images should be enlarged or reduced for printing.  While not exhibition ready, seeing the artwork in this preproduction state is a rare glimpse into the creative process of the artist!

After the drawings were carefully removed from the illustration boards, using conservation tape removal techniques, some unique features were discovered on the verso of two illustrations.  The drawings were digitized to document their condition prior to exhibition.  Digitized images of the backs of two illustrations are shown below.

Left: Verso of “And then she dropped her sister’s marbles on the floor” showing an impression of a Windsor and Newton watermark. Right: verso of “No Nora in the Mailbox, No Nora in the Shrub” with a prior sketch crossed out on the back.


To visualize how the illustrations would look in their frames, mock up window mats were created to experiment with how the drawings and captions should be arranged.  Below, the frame on the left centers both the artwork and the caption with a small margin around the art; whereas the frame on the right centers mostly the artwork with a much larger margin around the art.  Ultimately, our aesthetic preference was the extra margin around the art since the artwork itself was not square.  We also decided that no matter what option we chose, we wanted the bottom of the caption to line up throughout all of the frames, whether there was a single or double line of text.

Next, the artwork was measured to estimate material costs for matting and framing.  Following exhibition preservation standards, Rising rag museum mat board, UV filtered glazing, and wood frames were selected by the Preservation Lab.  We choose using glass over Plexiglas glazing so there would be less concern of harming the glazing surface with cleaners.  Because the artwork will be displayed a children’s height level, we also took into account how the artwork will be hung.  With the aid of security locking devices, the frames are not removable from the wall by the public, therefore there will be no danger of the frames falling.
To mimic how the artwork was mounted on the original presentation boards (preserving the artist’s intent), the work was matted with captions from the children’s book added below the art.  The artwork was mounted with Kozo (mulberry) tissue v-hinges that were pasted to the back of the artwork and then adhered to the back mat with with Zen Shofu wheat starch paste.  To maintain a 45% relative humidity environment, the matted artwork was housed within a sealed archival framing package.

Kozo hinges were adhered to the verso of the drawings with Zen Shofu wheat starch paste.


The hand colored drawings were then attached to the back mat using the kozo v-hinges, also adhered with wheat starch paste. The hinges were lightly pressed under weight to dry using pressing stacks.


Landscape window mats were hinged along the top edge with P90 Filmoplast tape.

The framing package contains:

  1. UV filtered Tru View Museum glass (purchased from our local art supply framing store).
  2. Float mounted artwork with two Usu gami hinges applied with wheat starch paste inside matting system. Window mat hinged to the left edge of back mat with P90 filmoplast tape.
  3. Blue corrugated cardboard used as a backing board to the matting package.
  4. Conservation note loosely set into place for future reference on the back of the corrugated backing board.
  5. Sheet of Polyester film added behind the corrugated board as a moisture proof barrier.
  6. To fully seal the entire package, the edges of all the materials were first sealed with pressure sensitive P90 filmoplast tape. A second foil backed framing tape from University Products (part of the Perma/Seal label line) was applied as a barrier to prevent moisture and gas exchange.
  7. A Dove Gray dust cover was attached to the back of the frames with 3M 415 double stick tape. Barcode labels and an additional conservation note were added to the dust cover.
  8. Lastly, Three security hangers were attached to the back of the frames; two at the top and one at the bottom.

With the exception of one frame, the original metal prongs were reused to secure the matting packages within the frame.  The one exception includes the booklet mounted with a sink mat, this thicker package required nailing brads secured to the inside of the frame rabbet to hold the matting package in place.

Booklet was mounted within a sink mat to account for the thickness of the object.


Before exhibit prep:During exhibition preparation:

After installation (the art is hung at children’s height!):

During Will Hillenbrand and Rosemary Wells visit on Sept. 15th, they discussed inspiration for books such and Max and Ruby (who are modeled after Ms. Well’s own children!) and delved into the subject of creating a “noisy” book. Mrs. Wells explained her process of conveying sound through illustrations – which by nature are a silent, quiet experience.
