BCIN, the Bibliographic Database of the Conservation Information Network, is the web's most complete bibliographic resource for the conservation, preservation and restoration of cultural property. A worldwide network of libraries and documentation centres contribute data on their combined holdings, including previously unavailable material from private sources, to the BCIN database. Cited literature includes: books, published and unpublished monographs and serials, journal articles, conference proceedings, technical reports and theses, audiovisual materials, software and machine-readable files. Available online since 1987, BCIN is a trusted resource for professionals, museums and other heritage organizations. It now contains nearly 200,000 citations, including the first 34 volumes of the Art and Archaeology Technical Abstracts (AATA), published between 1955 and 1997.
