Hi, We are experiencing intermittent problems with UC-eLinks from PubMed. UC-eLinks is slow and the UC-eLinks menu window can be missing citation information and links. This is due to problems with the NCBI Entrez search tools at NLM. They are aware of the problem and are working on resolving them but at this time there isn't an ETA for when the problem will be fixed.
