I read the message you posted. I believe Librarians & Teachers
do like to receive mailings - one major proviso - the subject matter
must fit their needs. I also think a small listing of your web
address would work, albeit, you must run in at least six issues - I'd
suggest Video Librarian; Library Journal and School Library Journal.
In summary and in the words of a person I admire (a nickel to
anyone that can tell me who said it:
"If you have something everybody wants, the world will beat a
path to your door - advertising helps."
