This report, Filtering and Filter Software, was written in 2003 for the American Library Association's Library Technology Reports series. It explores the issues associated with using Internet content filters in libraries. Throughout the report, specific products are referenced and the differences discussed.

Readers who wish to understand the myriad issues at work when filters and libraries come together will benefit from reading each chapter in order. Each chapter is also designed to stand on its own and provide targeted assistance for libraries considering filtering, selecting a filter, or implementing a filter.
