Medline: Citations and abstracts to worldwide biomedical literature including research, clinical practice, administration, policy issues, and healthcare services. It includes the allied health fields and the biological and physical sciences, humanities, and information science as they relate to medicine and health care. Indexes approximately 5,400 journals from 70 countries, plus chapters and articles from selected monographs. Although coverage is worldwide, most records are derived from English-language sources or have English-language abstracts. Abstracts are included for more than 75% of the records. Sources of information in Medline include Index Medicus, Index to Dental Literature, and International Nursing, as well as other sources of coverage in the areas of communication disorders, population biology, and reproductive biology.

OldMedline: The citations in this database are for articles originally printed in hardcopy indexes published from 1946 through 1965.

Medline In-Process & Other Non-Indexed Citations: PreMEDLINE (PREM), the National Library of Medicine's (NLM) in-process database for MEDLINE, provides basic information and abstracts before a record is indexed with MeSH heading(s) and added to MEDLINE. PreMEDLINE encompasses information from Index Medicus, Index to Dental Literature, and International Nursing, as well as other sources of coverage in the areas of allied health, biological and physical sciences, humanities and information science (as they relate to medicine and health care, communication disorders, population biology, and reproductive biology). New records are added daily to PreMEDLINE, appearing when the content of the record meets the scope of the PreMEDLINE databases. After MeSH terms, publication types, GenBank accession numbers, and other indexing data are incorporated into a PreMEDLINE record, the completed citation is added to MEDLINE. Completed PreMEDLINE records are added as citations to MEDLINE on a weekly basis. Records that do not receive indexing remain in Medline In-Process & Other Non-Indexed Citations.

IndexCat: IndexCat is a digitized version of the printed Index-Catalogue of the Library of the Surgeon General's Office. It contains material dating from the 1400s through 1950 and is an important resource for researchers in the history of medicine and the history of science, as well as for clinical research.

IndexCat contains over 4.5 million online references to over 3.7 million bibliographic items. 2.5 million items are primarily journal articles; 250,000 items are monographs (books, pamphlets, and reports); approximately 300,000 items are dissertations (theses); and 16,000 are journal titles. Users may limit IndexCat searches to specific series, volumes within a series, or a combination of both. A simultaneous search across all five series is the broadest search and is the default search setting.

Series 1 and Series 2 include portraits as separate citations, but Series 3, 4, and 5 indicate portraits in descriptive notes for monographs and dissertations. As in the printed series, Series 4 of IndexCat is incomplete. It includes citations printed only in the first half of the alphabet from A-Mn. The last half was never published. Series 5 excludes journal articles; the primary coverage is monographs, dissertations, and pamphlets with 1950 imprints or earlier.
