PubMed is now available only in a redesigned format. Please see the following article which describes changes to PubMed: http://www.nlm.nih.gov/pubs/techbull/so09/so09_pm_redesign.html.
The goals of the redesign are to make PubMed easier to use, simplify the interface, refresh the look, better organize the text on the screen, and promote scientific discovery.
We recognize that this new look for PubMed is a significant departure for all of our users, and we are committed to assisting you in making as seamless a transition as possible. If you have any questions about these changes or would like to schedule a research consultation or instructional session, please don’t hesitate to call email us firstname.lastname@example.org, or contact a liaison librarian directly, via http://ebling.library.wisc.edu/liaison/
In addition, we will be offering drop-in sessions later this semester. Check our class schedule http://ebling.library.wisc.edu/classes_tutorials/ for dates.
