Schirmer's Giant Book of Intermediate Classical Piano Music

This book contains 269 pieces by 3 composers, covering early intermediate and, I guess, just 'intermediate'. (There is a separate book of 'upper' intermediate pieces.) Some of these are also in the Early Intermediate book.

The links below are to scores on MuseScore.com, which you can both download and play, in most cases, so you can hear the piece while trying to learn it. The 'official scores' cannot be downloaded or printed, without payment, and cannot always be listened to, at this time, though my sense is that more and more of them can be. I've also included links, in some cases, to IMSLP.org, the Petrucci Music Library.
