The Z39.50 Information Retrieval Protocol is a proposed ANSI standard for the retrieval of bibliographic information that originates from the library community in the United States. Unlike previous interlibrary loan protocols designed by the library community, Z39.50 is intended to be the basis of an end-user service.This paper provides a brief introduction to Z39.50, then discusses the shortcomings of the protocol that were discovered as a result of implementation experience.
