This book was conceived in a somewhat different context. This is an attempt to present the idea of Library and the dissemination of the in-formation from antiquity to the present day. The author shares the view that past events, their accumulation and extrapolation are a bridge to the future. For over 5,000 years libraries have preserved the memory of humanity. They have passed through various metamorphoses. Today libraries are behind the wonder of internet. As a result of accumulated experience in the organization principles, search, structuring and presentation of information resources, libraries with good reason can be defined as a basis of new information technologies, where they are accumulated and extrapolated. In the first years of the new millennium libraries faced a number of challenges, changes and serious competition (Open Access. Open Sciences, Mobile Communication etc). They were a cross-point of many processes and phenomena, related with the information society and an increasingly globalizing world.
