Free Article Indicators on PubMed® Summary Display
The PubMed Summary display format has changed to include information about the availability of free articles from publishers. In addition to the existing link on citations showing what is free in PubMed Central® (PMC), a new link indicates if the article is freely available at the journal's Web site. Some citations have a link indicating the article is free from both PMC and the journal. The links all go to the AbstractPlus display where icon links to PMC and journal sites display.
For some LinkOut library participants, their subscriptions to journals that provide online access can greatly increase the number of "free" articles available to patrons as compared to what is shown by free indicators on the Summary display. Patrons can use My NCBI to create a filter for their library in order to easily determine what additional articles they can view. Instructions for creating filters can be found in the PubMed Help.
Alternatively, LinkOut libraries can create a My NCBI shared account that includes a filter for holdings. Patrons who use a library's customized URL to PubMed will automatically have the filter activated. The My NCBI Institutional Account feature for LinkOut has been revamped as the Shared Settings feature. See the article Shared Settings in My NCBI for more information.
