1. Publications describing NCBI services in peer-reviewed journals:
- As a general reference, use the Database Resources of the National Center for Biotechnology Information article published in Nucleic Acids Research (NAR). Use the Citation link on the right side of the PMC view of this article to obtain the citation in the desired format.
- Check through this PubMed listing to locate citations/papers on individual NCBI services of your interest.
- For the BLAST® services, use these BLAST references.
