Subject matter research services are often called "looseleaf" services. Many are actually published in looseleaf binders so the publisher is able to update individual pages or sections as necessary.
Subject matter research services are also available in many other formats, including bound print volumes, CD-ROMs, and internet databases.
A subject matter research service may contain some or all of the following types of information:
