Databases?

I use the IMDb for movies and TV. It’s simple and handy.
Are there any similar database’s for music and books?

*Mod; if this constitutes a poll feel free to move it.

Thanks Sam, precisely what I’m looking for.
Now for Books/Authors?

Well, there are a couple, but I’m not sure if they are exactly what you’re looking for.

Bibliomania

the Digital Book Index

But both of these tend to focus more on digital books available to read online.

You might also try looking at the list at [url"http://www.ipl.org/div/subject/browse/hum60.60.00/"]the internet public library and see if any of them are what you’re looking for.
