Storage Housings for Cased Photographs

Introduction


The Iconography Collection, which I have been working with this year, includes many non-traditional items, such as paintings and three dimensional objects, as well as items of various sizes. As this is a library, most of our storage spaces are divided into typical library shelving, and it can sometimes be a challenge with this type of collection to keep items in the desired order while using the available space efficiently and providing proper protection for the objects. This subject was also addressed in the recent Northwestern University "Beyond the Book" Blog Post by Stephanie Growler, entitled "Fitting In: Storing Objects in Library Stacks" .

I was inspired by this blog post to create a folder structure, similar to the one depicted for petri dishes, during my rehousing project for a collection of cased photographs within the Iconography Collection. While this group of cased photographs is considered a single item, as it is cataloged under one item number, Iconography 1507, it includes over 75 cased photographs, mainly daguerreotypes and ambrotypes and a few tintypes.

I wanted to improve the housing because the cased photographs were placed haphazardly in two boxes and were housed in poor quality envelopes. They were not properly enclosed or protected and were poorly organized, which increased the risk of damage and dissociation.

The Challenges


- Utilize the same exterior boxes so that the objects will occupy the same space on the shelves.

- Objects needed to be stored vertically. Housing objects horizontally was not the best option for the space, given the large number of small items, and the objects needed to stay in the same place on the shelves in order to maintain chronological order.

- Housing items individually on the shelves was not ideal because this would have resulted in many small, loose items, as well as inefficient use of the space.

- Standardize the housing for a majority of the objects. Most objects were 3 3/4" x 4 3/4" or smaller, but several were larger.

- Keep the objects in alphabetical order within the boxes while meeting other goals.

- Create secure, durable enclosures with archival (non-damaging) materials.

Solution

-Decided to modify pre-made folders to fit approximately 2 cased photographs per folder, with two folders fitting next to each other inside of the box. This allows for enough protection while taking up less space than pre-made standardized boxes. Using pre-made folders also saves time and expense.

        - Bonus: Only 3 items did not fit inside the chosen folder size, which meant the folders could be           mostly standardized. Out of 35 folders, only 3 required larger dimensions.

-Used blue corrugated board scraps for the walls of the boxes. This gave me the opportunity
to use up many scraps, while providing added protection for the objects.

-Added Volara on lids, custom fit to the individual compartments, to create added support and pressure.

-Added Mylar strips to lift cased photographs up and out of compartments, or thumb-slots if possible.

-Embedded Velcro in walls of folder. This allows the folder to be flush on all sides and does not
take up more space. However, the Velcro is time-consuming to attach. We used PVA which took a long time to dry, and was not always immediately successful if not enough PVA was used.

Once I had completed a prototype and determined a workflow, Deborah Howe and Stephanie Wolff helped to make many folders, which made the project go quickly!

Tips for batch construction of folders


1. First group the cased photographs in pairs according to alphabetical order and size to determine the      number and size of folders needed.

2. If trimming the folders so that two will fit adjacent in the box, do not use the spine to square the         edge! The spines are cloth and are irregular. Use the boards only, otherwise you can end up with off-square, irregular folders.

3. Calculate the number of strips of corrugated board you will need in which sizes, then cut these
    standardized pieces accordingly. This takes time, but it is worth it. Extras are also good idea.
 
         a. In general, avoid making strips thinner than 1 inch. If walls need to be thinner than this,                        then turn on their sides.
         b. Avoid leaving space in the joints between the walls, and make sure the walls are as flush as                  possible.

4. Use a tape gun or double-sided tape to build walls from corrugated wall pieces.

5. When attaching the walls to the folder use PVA. At first I attached to the bottom of the folder            using double-sided tape, but found this resulted in an unstable structure. PVA in the joints between     the walls is also key.

6. Cut space on top of a wall for Velcro, and use sandpaper on lid to make slightly rougher surface.         Attach with PVA and weight. This will likely need about 8 hours to dry, but longer is always               better.

7. It is recommended that you allow the Volara to dry under a good amount of weight, then close the       box and weight more. Otherwise, you can may get a lot of warping of the lid.

The design may be modified slightly (and easily) to accommodate cased photographs of different sizes:






In the end, we made 35 folders. Of these, 16 folders were exactly the same inside and out, 32 have the same exterior dimensions. Only 3 needed larger folders, which are oriented horizontally.

Space Oddity: Dartmouth Canes

The American Library Association annual conference concluded in early July and while at the conference I gave a presentation to the Book and Paper Interest Group of the Preservation and Reformatting Section of the Association for Library Collections & Technical Services. The theme was "Space Oddity" and the presentation had to be given in an Ignite Talk style, in our case 15 slides at 20 seconds each for a total of 5 minutes.

What follows are the slides and my comments for each.

Canes of Dartmouth College
1800-2008






This storage solution for Dartmouth's collection of canes was created by North Bennet Street School summer interns, Becky Koch and Laren Schott, with oversight from Deborah Howe, the Collections Conservator.












The problem was how to store these wooden canes. The bulk of the collection were canes hand carved by Dartmouth students during their senior year. The most common embellishment of the cane head is what is know as the "Indian Head Cane".


Here Deborah and the interns are arranging the canes by size.

Prior to this treatment the canes were stored in a type of umbrella stand with open sides and very little protection. The canes were not stable and would slip and slide within the stand. The enclosure solution used both pre-made boxes and custom fit inserts. To begin, the canes were sorted by size. Most of the canes were a standard length. 




The canes were surfaced cleaned prior to rehousing them. To surface clean them our interns took dry and sometimes slightly moistened (with water) cotton swabs and wiped away soot and dust. No repairs were necessary. All of the canes were in generally good shape.




The housing solution consisted of adapting a pre-made box to hold an insert tray, and thus created two layers for storage: a bottom layer and the insert tray forming the second layer.

Pre-made box.
The pre-made box was purchased from Gaylord. It was made of polypropylene measuring 
38 inches x 24 inches, and about 6 inches deep.


Using heavy, natural cotton webbing, handles for the pre-made box were created and reinforded with Vyvek to help support the weight. The Vyvek is shown inside the box, where the cloth webbing is threaded through. Deborah suggests that in the next iteration of this box she would improve it by adding support stops for the insert tray to the pre-made box.



The insert tray was fabricated from 2 pieces of blue, acid free corrugated board. Adaptations were made because a single sheet was not large enough to build the walls up.

     





For the insert box special attention was also paid in building handles that could withstand the weight of the canes. To do this the cotton webbing was threaded through the bottom of the tray that had been reinforced with a layer of 40pt board for extra support.
                       































In order to separate the canes from each other dividers were made from 10 point map folder stock. The folder stock was creased and folded to create a pocket. Each pocket was about 2 inches deep and 3 inches wide. Two pieces of folder stock were needed to create each divider layer.


To construct the dividers score lines were determined and a pattern was made from a strip of paper. These marks were transferred to the 10 point folder stock.


Both short edges of the 10 point were marked, then the pencil marks were lined up on the edge of the table. The 10 point was creased cross grain to maximize length and to improve rigidity in the walls of the dividers. Because of the length creasing on the board shear was not possible.



The dividers were placed on both the bottom layer and the insert tray. They were not attached in any way – although they could be if desired. Deborah suggests sliding in 40 point strips inside the divider walls to give additional support and rigidity.






With the dividers in place the canes were arranged on each layer and the insert tray placed on top. Each box can hold 16 canes: 2 layers of 8 canes each. When each box set was constructed it was bar coded and labeled with the archival series number.

There were also canes of irregular size: longer than the rest or with heads that made it difficult to apply a standard approach. For these canes the divider was placed diagonally in the box and the canes arranged accordingly.




By the end of the project over 100 canes were cleaned and stored in 8 custom boxes for 24 linear feet, and shelved in the Special Collections remote storage facility. A finding aid for the cane collection now lists the canes by individual box number thus improving not only the storage but also making it easier to retrieve a single cane. By this single conservation treatment both storage and retrieval have been improved.



Thanks to Deborah Howe for collaborating with me to create this Ignite Talk and to Becky Koch and Lauren Schott who designed this storage solution.
