Some recently established national programs for serials automation are evaluated from the point of view of the practicing librarian. (Author/PF)

A model to calculate the costs of automated cataloging systems based on cataloging copy in a system's data base is developed. The costs derived by the model for two systems, OCLC and BALLOTS, are compared to the costs of an existing manual system. (Author/KP)

Four categories of automated network catalog products and services are examined. The advantages and disadvantages of (1) the on-line cathode-ray-tube (CRT) display, (2) the line-printer produced card, (3) the photo-composed book catalog or catalog card, and (4) computer-based microforms are all reviewed.
