"""An essential volume for any library's professional reference shelf-- even if the library does not use the DDC as its main classification scheme. It also serves as a great instructional primer for newly-minted technical services librarians seeking succinct, easy-to-access information about how the DDC's tables, charts, and indexes are arranged, governed, and function ... [It] has the potential to serve as the primary DDC handbook for years to come."" -- Technicalities"
