This classic cataloging tool has been updated to include the 22nd edition of the Dewey Decimal Classification, as well as almost 1,000 additional sets of class numbers and corresponding Library of Congress subject headings. As with the previous edition, it is arranged in three volumes: LC to Dewey, Dewey to LC, and LC subject headings to both. Each volume of the three-volume set contains the same list of classifications in the two systems and corresponding subject headings, but arranged differently. Scott is affiliated with Federal Libraries. Annotation ©2006 Book News, Inc., Portland, OR (booknews.com)
