This second LARC (Library Automation Research and Consulting Association) automation survey presents a number of significant improvements over the first survey. Although the number of survey reports has not increased greatly, all of them have been updated and reflect, as nearly as it is possible to do, the current status of automation operations for the reporting libraries. The most significant change is in the provision of indexes so that the reports are accessible from a number of approaches. The survey is organized into three parts: Part I. Application of Automation in American Libraries; An Analysis of the LARC Survey Returns; Part II. Indexes to Survey; and Part III. The Survey Reports. Various aspects of the survey are dealt with in the following sections: (1) the analysis of the LARC survey returns, (2) the indexes, (3) uses of the indexes, (4) the survey reports and (5) future editions.
