CHC Research Library Catalog Progress

In addition to our archival collections, the CHC is home to a research library containing over 1000 volumes pertaining to Cambridge history, architecture, and residents. While plenty of these books are widely held in other libraries, many are rare volumes not found elsewhere. To increase the usability and accessibility of our collection, both for CHC staff and outside researchers, archives assistant Emily has spent the last several months creating a library catalog. This catalog will eventually be available online through an open source online catalog platform called TinyCat, so stay tuned for the announcement and read on to learn about Emily’s progress.

This project started with a spreadsheet.

Several years ago, a previous CHC archivist started adding books to this spreadsheet. She included fields for the basic bibliographic data needed to identify a book: title, author, publisher, date of publication, etc. However, she left the CHC before this spreadsheet was complete. I took over the project in February, checking the list against the volumes on the shelves of the library, correcting or adding information as necessary, and adding volumes that had been added to the shelves in the period after the previous archivist left and before I started.

The spreadsheet has evolved since then. I added and removed fields, changed classification systems, added call numbers, removed call numbers, added subject headings, removed subject headings, changed collection headings, and color coded EVERYTHING. It’s a work in progress.

Currently, I am almost finished assigning call numbers to every volume on our shelves. (Many more will be added later, but one step at a time.) When this step is finished, it will be time for the Great Reorganization, an all-hands-on-deck event when we will be removing everything from the stacks and reordering the collection by call number. We will be making flags to place in each volume (all 1,000+!) so users can find what they’re looking for. And every volume will be added to our online catalog, available for anyone to use, from anywhere in the world. As an archivist committed to making all information as freely accessible as possible, I am really excited for this thing to go live.

*An Ode to Online Catalogs and the Library of Congress Classification System PDFs*

Many of the call numbers I’ve assigned to each volume were found in other online catalogs. The Library of Congress holds millions of volumes and must employ hordes of catalogers, so they are the definitive source for LC classification standards. WorldCat is a “global catalog of library collections” through which one can search the online catalogs of universities, public libraries, and archival collections all around the world. These sources were invaluable to me in this process. However, some of our materials are so rare they can’t be found in any other catalog. Many others were arranged in a way that didn’t make sense for our collection. For these items, I created call numbers from scratch using the Library of Congress classification schedules, basically guides to the LC Classification System, available as PDFs, that include almost any possible classification.

In the search results page, you can see the call numbers for the volumes I’ve already added. F74.C1 is the basic classification for anything about the history of Cambridge.

Are you as excited about all of this as I am? Do you want to know more about the Library of Congress Classification System and why it is vastly superior to the Dewey Decimal System? Let us know in the comments!

Preservation at CHC

Recently, the staff here at the Commission performed some summer cleaning in our archives and library storage. After relocating a few boxes, our archives assistants assessed the physical states of some of the materials. Among the collections were a collection of Civil War memorabilia, photographs, an oversize atlas, documents, and an oversize volume of architectural plans.

Many of the items had already been stabilized and were properly housed. Others were in need of repairs or other types of preservation. Two items were in need of immediate preservation work: a volume of architectural plans and a photograph.

The architectural plans are bound in a volume measuring around 24 x 20 inches. This volume represents personal collection of plans of an engineer at the Cambridge Water Board, and the plans date ca. 1860s-1870s.

Our digitization assistant, Meta, dry-cleaned the area, and repaired the tear using Japanese tissue and wheat starch paste.

The final product

The photograph, titled “Survivors of the First Company Raised in the United States for Suppression of the Rebellion” comes from the George H. Hastings Civil War Memorabilia Collection and was taken ca. 1880.

The photograph had been held to a mat frame with adhesive. Glues manufactured during this era were often made from animal products and rubber. These products are now known to congeal and harden over time.

Our archives assistant, Emily, carefully removed the hardened glue from the verso of the photograph with a micro-spatula, thus protecting this photograph from any chemical or physical damage.

In the archives field, professionals and students are always working hard to provide access to our materials, both physically and digitally. Our work here at the Cambridge Historical Commission is no different.
