Not necessarily. Publishers frequently require authors
to assign copyright to them on
publications. Check the terms of your contract or agreement. Even if you have assigned or
exclusively licensed your copyright to the publisher, such contract often reserve for the author
some rights. For example, most major publishers allow the author to continue to use their works
freely for research and teaching purposes including, sometimes, intranet or even Internet postings
(provided sufficient acknowledgment of the publisher is included).
