The three papers in this collection on library statistics were presented at the 1984 IFLA general conference. In "The Management Use of Library Statistics," Geoffrey G. Allen of the Western Australian Institute of Technology discusses current uses and misuses of library statistics and illustrates some practical applications of statistics by citing real library management situations. A second paper by Allen, "The Compilation of Library Statistics: Some Problems in Definition and Collection," exemplifies, from recent experiences in Australia, the practical problems that beset the compiler of statistical data on library operations. The third paper, "Definition and Collection of Library Statistical Data: The Nigerian Experience," by J. A. Dosunmu (Nigeria), summarizes efforts by the National Library of Nigeria to collect statistical data and evolve a national system for its collection, control, and standardization. Definitions and notes, recommendations, and a questionnaire used in this effort are appended. (THC)
