The possible licenses that are permissible on IMSLP:
- Scans of old printed or manuscript music: NONE - public domain only.
- Manuscript scans (composers dead over 70 years): NONE - public domain only. (unless first published less than 25 years ago)

The Six Creative Commons Licenses
The Creative Commons licenses use 4 types of restrictions:
- Attribution (by) -- Users must attribute the work to the creator of the work.
- ShareAlike (sa) -- Users must license derivative works under the same, similar or a compatible license.
- NonCommercial (nc) -- Users may not use the work for commercial purposes.
- NoDerivs (nd) -- Users may not create derivations of the work or give non-verbatim performances.
*(See the license for definitions of "derivative" and "adaptation")
Combinations produce the six licenses in increasing restrictiveness:
Performance Restricted Licenses
The Performance Restricted licenses are usually used when a composer uses a Performing Rights Organization (PRO) (e.g. ASCAP, BMI) to collect performance royalties. These licenses do not allow free live, broadcast or transmitted public performances, or recordings except as exempted under the copyright statutes of various countries. All performances, whether live, broadcasted or transmitted, are subject to payment of performance royalties to the PRO.
There are six Performance Restricted licenses, mirroring the six flavors of Creative Commons licenses. The only major difference between a Performance Restricted license and its Creative Commons counterpart is the performance restriction.
