From the CDC: "Welcome to the Smoking & Health Resource Library. The database contains abstracts of articles from medical and professional journals; books and book chapters; dissertations; reports; conference proceedings and conference papers; government documents from federal, state, local, and foreign entities; fact sheets and policy documents from U.S. and international nonprofit organizations; and other documents. New Citations added to the database in the last eight weeks are also available. New Citations include recently published tobacco-related articles from peer-reviewed journals of behavioral, scientific, and medical literature."

"The Smoking & Health Resource Library includes nearly 76,000 abstracts of journal articles, books, dissertations, reports, conferences, government documents, fact sheets, and policy documents from nonprofit organizations. It is a useful site, but the search function has an unfinished quality. Background information on the Library is part of the Overview and FAQ pages, located, somewhat confusingly, under Search Tips. Help is located under both Search Tips and Overview. Quick Search looks for keywords and author, and Advanced Search for keywords, author, article title, journal title, and years. No option, including keywords, will search the document type, language, or audience fields. The thesaurus is not searchable, and the search mechanism for nonjournal publications is not clear.

In Quick Search, users may retrieve all records by clicking on the search button without entering any terms, and sort results by year or alphabetically by title. Sorting via Oldest to Newest produces some inaccurate results; the first record listed with a date is from 1956, but limiting to records between 1800 and 1900 in Advanced Search retrieves two documents. In general, the results page for older, finished citations displays the authors, article title, year, and a fragment of the library-generated abstract. Some records display the journal title on the results page, and some must be opened to reveal the source. New Citations, added at a rate of 1,800 annually, are the only ones that link to PubMed; unfortunately this link disappears when the records are finished, so that users lose PubMed's linkages to abstracts and full text. All in all, this is a good, free resource that will be even better if the search function improves. The site's audience ranges from researchers and librarians to health professionals, educators, and students." from Choice, March 2009
