From here:

Copyright protects the particular way authors have expressed themselves. It does not extend to any ideas, systems, or factual information conveyed in a work.

The safest course is always to get permission from the copyright owner before using copyrighted material. The Copyright Office cannot give this permission.

When it is impracticable to obtain permission, use of copyrighted material should be avoided unless the doctrine of fair use would clearly apply to the situation. The Copyright Office can neither determine if a certain use may be considered fair nor advise on possible copyright violations. If there is any doubt, it is advisable to consult an attorney.
