    Footnote
    Rez. in: Knowledge organization 28(2001) no.4, S.206-208 (C. Arsenault):"Overall, this is an excellent work, on an ever increasingly pertinent topic. This long-awaited second edition provides a thorough and comprehensive update of an already important text. I very highly recommend it to professionals and academics alike ; both neophytes and veterans will find it valuable. It is a fundamental work that cannot be ignored in the field of subject analysis and retrieval for all bibliographic systems, including online catalogs."
