You have to enter "Petrucci Music Library".

I've found this amazing site a long time ago and the other day I thought that it was a great idea to share with you all if you didn't knew it before.

I hope you enjoy it!

Wow! That's the mother load. Great link, Ramiro!

In the IMSLP there's a link to this site when you enter the Mozart part I think, but anyway I posted it because it's Mozart haha he deserves a whole post.

Wow, awesome, thanks for sharing this!

I was just about to post this link
To save on redundancy I'll just post here to bring this back into topic.
This music library is such an amazing resource. I'm currently looking at various piano transcriptions for a multitude of composers and this place has a great collection - it's save me a job from going to the library and placing orders at music shops.
Not sure how much guitar music there is but if it's sheet music you're after, look here first.

wow that is a great archive man! Thanks for sharing the link!

Hahaha it sure is a great place!!!

They tried to close it in the past and they did but now's back
