- Library Music Source
This seems a good opportunity to mention other resources available on the internet. Some of these are free, others have to be paid for:-
- IMSLP/Petrucci Music Library - Free Public Domain Sheet Music; an online database with a lot of historic collections, free to download.
- Sheet Music Direct: Download and Print Sheet Music for Piano, Choir, Guitar Tabs and More
- CD Sheet Music Online
- Sheet Music Plus - For Piano, Guitar And Choral Music
- National Library of Scotland - Digital Gallery (hundreds of early Scottish music scores, free to access and download.)
- The Internet Archive at Archive.org offers old music and old recordings, besides the more expected old books - well worth a look!
