Open or free statement
Certain sites call themselves open, free, or libre (or variations thereof).
It is a different issue of whether they actually are open, or how open, since there are various ways the term is used. The actual level of openness (whether the resource is free for the user to reproduce, change, build upon, use commercially or distribute) is dependent on how the material is licensed.
