The NLM Catalog provides bibliographic data for almost 1.4 million NLM holdings including journals, books, manuscripts, computer software, audio recordings and other electronic resources. Each record is linked to the NLM LocatorPlus service as well as related catalog records with similar title words or associated MeSH terms. The Journals database contains all journals referenced in any Entrez database. Currently holding almost 24 000 records, the database indexes for each journal the title abbreviation, the International Organization for Standardization abbreviation, publication data and links to the NLM catalog and all Entrez records associated with articles from that journal.
