The Library of Congress SCIENCE TRACER BULLET SERIES contains research guides that help you locate information on science and technology subjects. With brief introductions to the topics, lists of resources and strategies for finding more, they help you to stay "on target."
These pathfinders from the Library of Congress Science Reference Services have been for quite awhile -- as far back as 1972, according to Reference Services Review -- but in our humble opinion, they don't get enough love. Covering a wide range of subjects in the natural and physical sciences as well as technology, they are updated from time to time, and the collection keeps getting larger and larger. Those available online date back to about 1990.
Each bibliographic-style guide focuses on a specific topic and includes such resources as introductory material, pertinent LoC subject headings, basic texts/other books/specialized titles, handbooks/encyclopedia/dictionaries, conference proceedings, government publications, technical reports, dissertations, abstracting/indexing services, journals and specific journal articles, vetted internet resources and additional information sources, including contact info for relevant organizations. New guides are announced on the What's NEW on the Science Reference Service Web Site page, which is also available as an RSS feed.
While you're visiting this section of the ginormous LC website, be sure and taker a look at some of the other resources available here, such as:
+ Science Reference Guides (bibliographies)
+ Selected Internet Resources in Science and Technology (vetted webliiographies)
