Interestingly enough, the day the FAQ about registering copyrights in groups posted to my blog, I received a letter from the Library of Congress about my most recent group registration. (Funny how things happen like that sometimes.) It is a form letter explaining a few particulars and referencing some rules that pertain to registering in groups.
I believe the “work not covered by copyrights” that might have prompted me to receive this letter is the inclusion of word art with my images. Words and text aren’t covered by copyrights but need to be trademarked. I admit to not always taking the time to take them out of my registrations. 🙂
If you want to see the referenced regulations, I’m sure you can find them at www.copyright.gov
Hope this helps!
