These Web pages are a resource for students enrolled in
LIBR 202, Information Retrieval. The outline below lists
the major topics covered in the class; the material may be
used by your instructor as required reading for a specific
topic, as an introduction, as a review, or as an optional
supplement to the material presented in class.
The outline is linked to overviews of each topic with a list of key concepts; tutorials, PowerPoint slides, handouts, and other materials may also be present. The "More" link may lead you to examples and other information. This Web site is always under construction, with contributions from all of the 202 instructors; some parts will be richer than other parts. If you find broken links or other outdated material, please let a 202 instructor know so that we can fix it. We'll also welcome information about other useful resources on these topics.
