Does anyone know a website of like, all authors, like a library of authors basically, I'm having a hard time finding one.

There are two sources at the links below. The first one if for American authors,
And the second is for international ones:

Alphabetical Listing of American Authors (http://www.nagasaki-gaigo.ac.jp/ishikawa/amlit/authorlist/listauthors.htm)

Lists of writers - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Lists_of_authors)

I've found this one to be useful:

Fantastic Fiction (http://www.fantasticfiction.co.uk/)
