Best Sources for Collecting Citations

What would experienced users recommend as the best sources for collecting citations for books, multi-authored books (assay collections, etc.), essays, etc?

By "best" I mean sources that give us the least citation formatting and content errors. For example, I take it Worldcat is probably one of the least accurate since there tend to be multiple entries to the same item and the info on items are often entered wrong. Amazon.com is another such source. As far as I can tell, the best sources would be the websites of our educational institutions, but even here I see some issues.

Also, if there are best sources depending on the particular type of work, please specify: Ebscohost databases for essays, university library website for books, etc.

Thank you very much,
José
