Lately, I've noticed that wikipedia is becoming a valuable source of information regarding authors and books.  Anyone here have any experience with it, or made contributions?

Other than that, I use amazon and fantasticfiction.

i use wikipedia to look up info on all kinds of things. on some authors they have a huge page and on others the pages are not so big,but it has a lot of good info on it as far as i am concerned.

I LOVE wikipedia!!!  I use Amazon and FantasticFiction when looking for book covers or specific publishing details, but when it comes to the substance of the book wikipedia is great!  The best is that even if wikipedia is lacking each page is usually linked to relevant subjects both within wikipedia and elsewhere on the web.  Even the resources cited can be found most of the time.  It's like an information gateway.
