This brochure describes the online information services at the New York State Library, which has online access to over 250 databases covering a broad range of subject areas, including current events, law, science, medicine, public affairs, grants, business, computer technology, education, social welfare, and humanities. Many of these databases are online equivalents of well-known printed indexes and abstracts, such as ERIC and Dissertation Abstracts; others, like Robotics Information Database and ABI/INFORM, are accessible only online. This brochure covers the advantages of online searches, explains how to submit a search request, and provides a sample DIALOG printout. The 89 most frequently used databases are listed according to subject category and briefly described. An alphabetical listing of these databases is provided in the index. (KM)
