The Dewey Decimal Classification System, popularly known as DC or DDC, was created by Melvil Dewey more than a century ago. Since then it has gone through constant changes and has grown from a 44 page booklet to four volumes. But its basic plan, notation and desire to serve librarianship has remained stable.
"The Encyclopedia of Library and Information Science provides an outstanding resource in 33 published volumes with 2 helpful indexes. This thorough reference set--written by 1300 eminent, international experts--offers librarians, information/computer scientists, bibliographers, documentalists, systems analysts, and students, convenient access to the techniques and tools of both library and information science. Impeccably researched, cross referenced, alphabetized by subject, and generously illustrated, the Encyclopedia of Library and Information Science integrates the essential theoretical and practical information accumulating in this rapidly growing field."
