This is a fairly incomplete post about the work that’s going on regarding adding BHL bibliography metadata to Wikidata. I hope to have several more of these posts before the end of the year!
Following some productive conversations on donating BHL bibliographic metadata to Wikidata, it was discovered almost immediately that BHL’s data is not terribly useful without some serious munging. One of the biggest problems with BHL bibliographic metadata is that it comes from lots of different libraries and museums, legacy cataloging systems, and various types of authority work. For example: BHL attaches Creator IDs to Author names, which is useful for identification and connecting titles and items to their Authors, but they are assigned automatically according to the character strings imported from specific fields in a library catalog’s MARC record. Despite (and perhaps because of) the use of varying authority files to control Author name strings in institutional catalog records, different libraries have contributed items by the same author whose names are are spelled, punctuated, and identified differently. BHL does not conduct authority control on BHL metadata, choosing instead to focus on improving access to items based on content rather than metadata. Fortunately, there are several different ways to go about reconciling and disambiguating data, and one of them is crowdsourcing. Continue reading “Wikidata and BHL Update: Part 1”
