The copyright is in the public domain because it has expired;
The copyright was injected into the public domain for other reasons, such as failure to adhere to required formalities or conditions;
SIA owns the copyright but is not interested in exercising control; or
SIA has legal rights sufficient to authorize others to use the work without restrictions.
However, restrictions may still exist. The SIA makes its content available for personal and non-commercial educational uses consistent with the principles of fair use.
