You can check on Youtube (or here) for some tutorials...They also give the notes in them. And I think it's a very easy way to learn!

But if you want to sheet music, you'll have to search for yourself on google or something. It's pretty easy to find. Just type the name of the song + artist and put sheet music behind it. It should give some results.

Otherwise take my first advice.

Is there anything in particular that you are looking for? I have a modest collection of sheet music, with a bit of modern stuff in there.
