Please note: following the release of the new version of PubMed, the results returned by E-utilities queries of PubMed may differ slightly from those returned in the web version of PubMed. A new PubMed API is currently under development: more information will be announced when available.

As new Insider's Guide classes are no longer being offered, this site is not currently being updated. Please refer to NCBI's E-utilities documentation for more up-to-date information.

Stay up to date with E-utilities

All new Insider’s Guide classes, as well as updates about the NCBI APIs, are posted to the NCBI utilities-announce mailing list. If you are interested in E-utilities or the Insider’s Guide, we encourage you to subscribe!

In addition to new course offerings, NCBI also posts general announcements and updates about the E-utilities API. This mailing list is an announcement list only; individual subscribers may not send mail to the list. Also, the list of subscribers is private and is not shared or used in any other way except for providing announcements to list members. The list generally receives less than one posting per month.

Additional NLM news and training opportunities are published in the NLM Technical Bulletin. You can stay informed of the latest updates by subscribing to RSS or email updates via the Technical Bulletin “Stay Current” page.
