This paper considers the ways in which information finding is changing in a world of digital information and associated search systems, with particular focus on methods of locating information that are distinct from, but complementary to, established practices of bibliographic description. The following three general approaches to identifying potentially relevant information are described: through bibliographic surrogates that represent an intellectual analysis and description of aspects and attributes of a work; through computational, content-based techniques that compare queries to parts of the actual works; and through social processes that exploit the opinions and actions of communities that author, read, and evaluate works, as well as the information seeker's view of those communities. Ways that computational content-based retrieval can help information seekers and techniques for making non-textual materials available are discussed. Three areas are explored as part of the context for the new bibliographic control: (1) bibliographic control is not just about rules and practices, it also depends upon a complex infrastructure of authority files and classification structures; (2) the networked information environment has a democratizing and empowering character; and (3) as part of the massive migration of content to digital form, we are approaching a crucial point in standards-setting.
