The National Library of Medicine Technical Bulletin is a public domain information newsletter of the Office of Engagement and Training, United States National Library of Medicine (NLM).

[1][2] The newsletter contains current news and information for NLM products and services, listings for NLM events,[3] and update notes for NLM offerings,[4] including PubMed,[5] MEDLINE,[6] and MeSH.

It was published on a monthly schedule until 1990, after which point it was switched to bimonthly.

[8] The newsletter's first issue appeared in 1969 as the MEDLARS/Network Technical Bulletin; it was changed after six issues to Library Network/MEDLARS Technical Bulletin.

After the 1998 transition to an online-only publication, printable versions of each issue were offered on the website.
