Librarians should evaluate if the current bibliographic metadata is adequate to support user friendly discovery.The bibliographic metadata should be in a system that permits user searching and accommodates links to and from the digital surrogate. Cataloguing is an essential part of the creation of the collection, and it should include decision about the protocol, level and detail of the description, and the language or language of the main catalogue; translation to any other language could be added in order to participate in national and international project and to provide wider access to the material. Other multilingual tools or protocols can also enhance access to records. The length and depth of the description should be balanced: their anticipated public and dissemination will influence these decisions. If adequate metadata do not exist, it should be created before digitization occurs. (See Chapter 4 for a detailed discussion of metadata.)
