I usually use the academic database that my public library subscribes to. I just have to put in my library card number, and get access to all the same journals, newspapers, and more that I had when I was at university.

Librarian answer- it depends on what you are looking for. Different databases for different purposes. +1 Heather. See what your library can give you access to. The good ones are $$$$.

Also State Library of Vic and Nat Lib Oz both give access to good list of databases after registration.

From Life scientist's room: Scopus (Elsevier) is said to be covering more of the informal literature, and is free for a limited time - I am afraid I don't know for how long. It is pretty good on the formal (published) literature

ISI Web of Knowledge, ScienceDirect, EBSCOhost are all rather extensive (commercial though). If you are looking for free search engines/ material then perhaps you can try BASE http://www.base-search.net/ and OAIster http://www.oaister.org/

Disclaimer that I work at Elsevier, but I would suggest Scirus.com, it is Elsevier's free science-specific search engine. If you have access to Scopus, that is the way to go, because it has Scirus search built in.
