Lubetzky's Work Principle
Discusses Lubetzky's insight that book and work coincide only when a work has been published in only one edition. Discusses the kinds of changes that create new manifestations, new expressions and new works, with specific discussion of works of photography, works intended for performance (music, dramatico-musical works, musical performances involving improvisation, and dance), texts with illustrations, music with words, works produced in stages (moving image works), revised editions, spatial data, serials, and interactive multimedia. Suggests that it might be possible to analyze pure categories of content such that a change from one category to another automatically results in the creation of a new work. Discusses the problem of how to name a work with a demonstration of how valuable it can be to name a work using author and title in conjunction (main entry). Discusses why Lubetzky's principles have not so far been carried out in our catalogs, including the delusion that artificial intelligence can replace human intervention, poor OPAC system design, and our complex system of shared cataloging.
