Using PubMed through the proxy server is currently causing searches to fail (i.e. you click the Search button and nothing happens). The National Library of Medicine is aware of the problem and working on a fix. In the meantime, there are two workarounds:
1. Use the standard PubMed address: http://www.ncbi.nlm.nih.gov/pubmed/. This disables the Find It button, which links citations to full text.
2. Use the UChicago-specific PubMed address and:
–First, select the Advanced link (directly below search box).
–Run your search.
If you have already tried to do a search before selecting Advanced, close PubMed, re-open it, select Advanced, and then run your search.
