This document summarizes a study on library automation software usage in university and special libraries in Sri Lanka. The study found that KOHA and Libsys were the most commonly used software in university libraries, with KOHA being the top priority, while WinISIS and Purna were most used in special libraries, with WinISIS as the top priority. The study also identified problems with insufficient funding, training, and support for library automation software. It recommends allocating more finances, conducting feasibility studies before purchasing software, providing training workshops, organizing user groups, and shifting to open source software.
