This is an excellent textbook. It is well organized and clearly written, explaining difficult concepts in understandable language for students. It covers the history of information organization in libraries, archives, and museums, as well as tools such as inventories, bibliographies, catalogs and indexes, and methods and standards of codification; reviews the history and development of the internet; describes different kinds of databases; and discusses metadata as a theoretical and practical concept, reviewing different kinds of metadata schemes. I highly recommend it.
