Lubetzky published three books that influenced the discipline of cataloging, and that are still influential in area of
information technology.
Librarianship in particular and
information science in general had not been revolutionized as much since the likes of
Antonio Panizzi,
Charles Ammi Cutter or
Paul Otlet.
Cataloging Rules and Principles and
Principles of Cataloging, as well as several periodical articles, solidified Lubetzky as one of the most significant influences in his field. He developed a rationalized approach to catalog code design, one that is even more relevant today as current cataloging principles are revisited and revised for a digital environment. His unfinished book,
Code of Cataloging Rules... unfinished draft (1960), was the basis for modern cataloging adopted by the first
International Conference on Cataloguing Principles (CCP) (1961) held in
Paris,
France, called the "
Paris Principles" (PP). The code which eventually emerged from the conference became the basis for cataloging practice in the 20th century. In 1967 these concepts were encoded in the
Anglo-American Cataloging Rules, which were used in
US,
Canadian and
UK libraries. Lubetzky is credited with renewing an emphasis on the "work" in library catalogs. This had been a feature of book catalogs of the early 19th century, but was not carried through to the card catalog. Whereas
Charles Ammi Cutter, a late 19th century influence on cataloging, had not distinguished between the idea of a "book" and the idea of the "work" in formulating his objectives, Lubetzky contrasts the two ideas, bringing back into play
Anthony Panizzi's original emphasis on the relationship between a title and all of the different editions of that title that might exist. Lubetzky's idea was that relationships among all the editions and variations of a given work and the author of that work, in all variations of the author's name, must be established and brought together so they can be found in one place. All the works of a given author, in all their editions, should be linked together. As Lubetzky said at a 1977 Los Angeles conference, "The Catalog in the Age of Technological Change": The catalogue has to tell you more than what you ask for…. The answer of a good catalogue is not to say yes or no, but … to tell [the user] that the library has [the item] in so many editions and translations, and you have your choice. ==Legacy==
