The following is a series written by archivists, academics, activists, and educators making available primary source material, providing pedagogical support, and furthering the understanding of Boston Public School’s Desegregation history. This post explains the technical underpinnings of the BPS Desegregation Project’s collaborative collection.
The simplest way to collocate our materials in a shared portal like Digital Commonwealth or DPLA is to consistently apply an agreed upon subject heading. There are numerous Library of Congress Subject Headings (LCSH) and Thesaurus of Graphic Materials (TGM) topical terms that could be applied to desegregation materials, including:
- Busing for school integration [LCSH]
- Busing (School integration) [TGM]
- Segregation in education [LCSH]
- School integration [LCSH and TGM]
- Segregation [LCSH and TGM]
Working in a vacuum, one institution could decide to apply the term “Segregation in education” to all desegregation materials, while another could decide to apply “School integration,” making it more difficult to connect these materials in a shared system. As a collaborative, we chose to apply “Segregation in education — Massachusetts — Boston — History” as an umbrella heading that can be used to collocate items related to desegregation and busing across institutions.
Recognizing that relying on a single subject heading may be too simplistic an approach for some collaborative collections, we’re also planning to explore the possibility of creating a DPLA App that would allow us to pull together a result set that combines multiple subject terms, which DPLA’s search functionality does not currently support.
Locally controlled list of names
Participating libraries agreed to apply name authorities from LCNAF whenever possible; however, many of the key local players in the desegregation movement do not have authority files with the Library of Congress. To ensure that we are expressing these names consistently, we created a shared document where we can list new non-LCNAF names used in our digital collections as they come up. In these cases, names are formed according to RDA rules.
Desegregation in the city of Boston is a particularly place-oriented topic; the issues, experiences, and reactions to busing differed greatly from one neighborhood to another. For this reason, we felt that adding geographic information, at least at the neighborhood-level, would be an especially valuable enhancement to our metadata records. We chose to express geographic data using TGN codes because it easily allowed us to apply values at the neighborhood level that would be automatically displayed in a linked, hierarchical form in Digital Commonwealth.
For example, applying the TGN code for the West Roxbury neighborhood of Boston (7015008) to this record results in the following linked, hierarchical display on the user end:
This geographic data will also allow users to visually explore items plotted on a map.
