Why does PubMed have multiple icons to get the full-text of an article?
There are three possible button icons. The Full-Text Article button indicates that we have a subscription to the journal electronically, and you can get an electronic full-text version of the article. The white Print Collection button indicates that the library subscribes to the journal in print only. It will provide information about how far back the issues the library owns and its location in the library. For more information on using the PubMed LinkOut features, please see our LinkOut page.
The Full-Text Locator button comes from another source and indicates whether we subscribe to the journal. If we do subscribe to the journal, it will link to the journal for you to get full-text of the article. If the journal is not available from us electronically or the library does not subscribe to the journal, the web page provides links to the catalog to search for print issues, a link to our Interlibrary Loan/Document Delivery form, and a link to contact us if you have any questions regarding access.
