While the best way to get to full-text of articles is to use our special link to PubMed or find the journal in our ejournal list, it is often easier just to Google the journal. If you are on-campus (ie. PWB) a lot of journal websites will recognize that and automatically give you access to full-text. From off-campus, though, this does not work.
If you have browsed to a journal and want to get to the full-text, try using our proxy bookmarklet. It will not work for all journals (some we buy from non-publisher sources), but it should work for many.
