Images published in journal articles deposited in PubMed Central can now be viewed and searched through the new NCBI Images Database. The database allows searches in many fields, including author, caption text, image size and date. Images may be used in accordance with the authors’ original copyright agreements with the journal articles’ publishers. So far the database includes 3 million images.
These images also appear in PubMed for those articles that have been deposited in PubMed Central. Clicking on the title for an article in PubMed brings up a record that includes an image strip. For more information, see this article from the NLM Technical Bulletin.
