If you have an OpenURL link resolver, such as SFX, you can create links back to your library holdings in the reference sections of Journal of Molecular Endocrinology articles. Such links help your patrons find the most appropriate copy of the article they are seeking at your institution.
You can set up your OpenURL configurations by signing in with your administrator user name and password.
For a complete explanation of what OpenURL is and why it is useful, see the article "Why OpenURL?" by Ann Apps and Ross MacIntyre, University of Manchester, in the May 2006 issue of D-Lib Magazine (Volume 12 Number 5, ISSN 1082-9873) http://www.dlib.org/dlib/may06/apps/05apps.html
