Referencing for the financially challenged
Rich students/scholars and those in institutions with the clout to get a good deal use Endnote (or some similar full featured expensive) bibliography and referencing tool. The rest of us use
Zotero, which is a brilliant free Firefox addin. That I have mentioned before but has got even better with version 1.0. Zotrero is great for taking the info from webpages, and often Library catalogues. It would extract the data from the University catalogue, but I'm no longer teaching at the Uni, and the College catalogue is not Zotero compatible. My workaround has been to search Google and click the Amazon link - Amazon is Zotero compatible - but that only works for recent books, enter
a tip from Judy Redman, that I bookmarked long ago, but only really tried today: use
WorldCat you can even get a Firefox tool to add WorldCat to your search box in the tool bar (I know the first one works, but do try the second):

OCLC WorldCat Catalog worldcat.org and away you go, fast, free and accurate referencing, now just click and paste into your essay/article/book...


Type in a search term (left) and you go to a page (right) from which you can select the book you need and from the page that appears (below)


and for a moment watch in wonder the Zotero "Saving Bibliography Item" message before right clicking the new entry, and presto you are ready to enter the item in your document!
Maybe I should do an instructional video for students...
