HubMed is found at http://www.hubmed.org and serves an alternative interface to the PubMed medical literature database. Any search strategies you use in PubMed may be used in HubMed and once you have the core skills for efficient searching of PubMed, HubMed offers many options that are not found in the original PubMed:
- Daily updates of search results via web feeds.
- Export citations in RIS, BibTeX, RDF and MODS formats, or directly to RefWorks.
- Unzip HubMed's import filter into Endnote's Filters folder for direct import into Endnote, or install the RIS Export plugin for direct import into ProCite, RefMan and older versions of Endnote.
- Use the Citation Finder to convert reference lists from PDFs into search results.
- Create lists of closely related papers using Rank Relations, then visualise and browse clusters of related papers using TouchGraph (requires Java).
- Graph occurrences of keywords in published papers over time.
- Tag and store annotated metadata for articles of interest.

I saw http://lab.blogs.com/lswg/2006/01/hubmed_pubmed_r.html and wanted to mention a new site for biomedical research:
http://www.biomedsearch.com
The site is free, and perhaps the most comprehensive biomedical site on the web. It has all PubMed and MedLine documents, plus mililons more (often in full text).
It also has account features such as portfolios to save documents, the ability to share documents (and comment on them) between users, and set up automatic alerts.
