The 1999 American Society for Information Science (ASIS) conference explored current knowledge creation, acquisition, navigation, correlation, retrieval, management, and dissemination practicalities and potentialities, their implementation and impact, and the theories behind the developments. Speakers reviewed processes, technologies, and tools, such as rights tracking, interfaces and visualization, search engine design and capabilities, and automated indexing and classification. They also described the appropriate or necessary operational policies, relevant legal issues (laws, legislation, and the European Union Directive), and possible international and domestic policies and regulations. This proceedings is organized into three parts. Part 1 contains the full text of 69 contributed papers organized under the following broad topics: how we search--the World Wide Web; digital IDs and codes; digital libraries; studying students' searching; knowledge management; rule learning, text mining, and virtual communities; metadata; electronic publications; interaction, navigation, and visualization, Web policies; knowledge capture and re-use; analysis and visualization; interaction, relevance, and design; digital library evaluation; information dissemination tools; special populations; domain specific applications; digital library searching; knowledge organization; work environments; digital libraries; representing users; image processing and retrieval; theory; and investigating information. Part 2 contains abstracts of special interest group (SIG) sessions and panels, and Part 3 contains abstracts of the plenary sessions. Author and SIG/Panel indexes are included. (MES)
