NLM Resources

ClinicalTrials.gov is the openly available federal registry and results database of publicly and privately funded clinical studies conducted in the United States and around the world. ClinicalTrials.gov is a vital resource for researchers, healthcare providers, patients and their families, and health sciences librarians who wish to consult the entire body of evidence on any particular topic.

This 14-week online class addresses increasing health information access and use by highlighting information about the National Library of Medicine’s NCBI Molecular Biology Databases. 

Learn how to use NLM resources to find drug and chemical information through a suite of on-demand classes. Complete all 3 classes for an in-depth introduction to NLM drug and chemical information resources, or complete the class that meets your needs for a specific population or commonly received questions.

This 1 credit-hour on-demand class introduces you to the basic concepts of medical terminologies (including what they are and why they are important), followed by a deep dive into RxNorm, an NLM-authored medical terminology specializing in drug information. Designed for health sciences librarians and other health information specialists seeking to serve more active roles in their health IT team and better support researchers. Expect to spend 1 hour learning through videos and exercises.

This work-at-your-own-pace class takes place over 3 weeks and will be available to you 24/7 in Moodle, our online learning management system. There are no set hours to be online each week. It should take you about 2 hours each week.

Join NLM staff for a highlight tour summarizing the annual updates for Medical Subject Headings (MeSH).

Every year, updates are made to MeSH, the NLM controlled vocabulary thesaurus used for indexing articles for PubMed and for cataloging books and other resources. This annual webinar aims to introduce those changes and provide examples of how the changes may affect you as a PubMed searcher. For more information about MeSH, see the MeSH homepage.

The National Library of Medicine (NLM) employs an authorized classification scheme called the NLM Classification. Designed for librarians who are creating or using a bibliographic record, this course will provide a basic overview of the NLM Classification, including how to apply Classification numbers, how to interpret NLM Call numbers, how to use the online NLM Classification system and where to go for more information for specific issues.
