This paper is a baseline document to review the latest technologies, algorithms and available hardware that can be used to build and automate a library system using Radio Frequency Identification technology as the infrastructure, allowing the librarian to track and manage real-life objects. The purpose is to review the current research that have been accomplished around this area in order to produce the best possible design, and implementation of a robust solution with maximum efficiency to automate a library system. The article first provides an overview of the radio frequency identification technology, its history, radio frequency principle, and how distance and frequency can affect the signal coverage distance. Then radio frequency identification structure and types are explained, after that the paper evaluates the latest researches in the radio frequency identification infrastructure and middleware. Finally the issue of radio signal collision is discussed, and corresponding anti-collision algorithms are briefly explained.
