PubMed is a free database including primarily the MEDLINE database of references and abstracts on life sciences and biomedical topics. The United States National Library of Medicine (NLM) at the National Institutes of Health maintains the database as part of the Entrez system of information retrieval.
Entrez Global Query is an integrated search and retrieval system that provides access to all databases simultaneously with a single query string and user interface. Entrez can efficiently retrieve related sequences, structures, and references. The Entrez system can provide views of gene and protein sequences and chromosome maps. Some textbooks ...
PubMed Central is a free digital archive of full articles, accessible to anyone from anywhere via a web browser (with varying provisions for reuse). Conversely, although PubMed is a searchable database of biomedical citations and abstracts, the full-text article resides elsewhere (in print or online, free or behind a subscriber paywall).
The Journals Database (one of the Entrez databases) contains information, such as its name abbreviation and publisher, about all journals included in Entrez, including PubMed. [17] Journals that no longer meet the criteria are removed. [18] Being indexed in MEDLINE gives a non-predatory identity to a journal. [19] [20] [21]
The Entrez Global Query Cross-Database Search System is used at NCBI for all the major databases such as Nucleotide and Protein Sequences, Protein Structures, PubMed, Taxonomy, Complete Genomes, OMIM, and several others. [9] Entrez is both an indexing and retrieval system having data from various sources for biomedical research.

The abridged edition is a subset of the journals covered by PubMed ("core clinical journals"). [12] The last issue of Index Medicus was published in December 2004 (Volume 45). The stated reason for discontinuing the printed publication was that online resources had supplanted it, [ 13 ] most especially PubMed , which continues to include the ...
The broad goals of the projects are to: Provide widespread access to a broad range of powerful statistical and graphical methods for the analysis of genomic data.; Facilitate the inclusion of biological metadata in the analysis of genomic data, e.g. literature data from PubMed, annotation data from LocusLink/Entrez.
