A product of the National Library of Medicine for the arrangement of library materials in the field of medicine and related sciences used internationally. The NLM Classification is updated twice a year with the winter edition published in January and the summer edition published in August. Publication of printed editions ceased with the 5th revised edition, 1999. Beginning with the 2006 edition, the NLM Classification is also available in PDF (Portable Document Format) at https://www.nlm.nih.gov/class/terms_cond.html

The National Library of Medicine's (NLM) Digital Collections offers a search-based Web service that provides access to the Dublin Core metadata and full-text OCR of every resource in the repository in XML format. Developers can use the Web service to build applications that query and link to these resources.

NLM History of Medicine Division's XML-encoded online oral histories provide access to a wealth of digitized transcripts, and audio when available.

Yearly citation totals from each year of the MEDLINE/PubMed Baseline referencing citations back to year 1781. These totals may increase over time for a particular year as new citations are added. For example, 25 citations were listed for the year 1800 in the 2018 MEDLINE/PubMed Baseline, while the 2019 Baseline includes 387 citations for that year.

This chart lists the major biomedical research reporting guidelines that provide advice for reporting research methods and findings. They usually "specify a minimum set of items required for a clear and transparent account of what was done and what was found in a research study, reflecting, in particular, issues that might introduce bias into the research" (Adapted from the EQUATOR Network Resource Centre). The chart also includes editorial style guides for writing research reports or other publications. https://www.equator-network.org/
