Searching the ideal unit of description.

The article discusses changes, which were observed in the isolation and attendance of unit of the description in the information-retrieval processes. The traditional unit of the description is too much connected with its carrier. The article is related to vision of the Tim Berners-Lee's Semantic Web and discusses some terms, e.g. information object, entity. It also presents definitions and interpretations of kinds of sources functioning in modern models of description like DC (Dublin Core), FRBR (Functional Requirements for Bibliographic Records) and also OAIS (Open Archival Information System) protocols and OAI-PMH (Open Archives Initiative Protocol for Metadata Harvesting). The metadata is easy to navigate (i.e. every kind of source without no regard to its form) by those new models. This new unit of the description should be introduced to librarianship and bibliographic practice.

Neighborly collaboration - a thing worth trying.

Part 1. Czech libraries as presented by Internet sources.
The first part of this article presents more significant and generally accessible Internet information sources that bring about better understanding of the organization, function and development of libraries in the Czech Republic. Both web addresses, and short presentation of websites and information services destined for libraries, library staff and library users have been supplied. Electronic periodicals with library content and other web sources related to more specific issues, such as big yearly domestic and international meetings/functions (during which current problems and latest achievements of the Czech librarianship are discussed) were also mentioned. It was also pointed out that Czech library sources are closely interrelated, and provide comprehensive information on domestic and international cooperation of libraries and their participation in various programs and projects.
Part 2. Assorted strategies, ideas, programs and projects in the development of Czech libraries. The second part of the article presents a number of conceptual and strategic documents containing various programs and projects that precipitated the dynamic development of Czech libraries and their co-operation of recent years. It was noted that some of those long-range projects, especially those involving the use of modern technologies, can be of great interest to potential followers, or to those who would wish for and expansion of inter-library co-operation in the Central-European region. A successful track record of Czech librarians' professional accomplishments was acknowledged, and Czech libraries' collaboration mechanisms along with project funding limitations was noted. This article presents The European Library - a multilingual website initiated under the auspices of the Head Librarians' conference of European National Libraries (2005). The main goal was to create common access to catalogs and digital resources of European national libraries. At present, the European Library consists of 23 national libraries, however, in the next three years, it is to be expanded by national archives and museums. The European Library is funded mainly by the European Union. There are predictions that by the year 2010, the European Library will contain about 6 million digital documents from all over Europe. Such content will thus become a part of the common European cultural heritage.
