The organisation of information supply systems supporting different user demands in libraries is a complex task. The services should be personalised and, in an ideal situation, independent of opening hours and the location of the user.

Spreading of digital formats, especially the Internet, has not simplified, on the contrary it makes the task more difficult, as the contents to be provided are available on a variety of media with different technologies: CD/DVD, databases, office applications, OPAC-s, Web addresses. Libraries are forced to accommodate these differences, as the user cannot be expected to be familiar with the different systems. A simple access point: "an information portal" should be established which is easy to comprehend for everybody.

It is also a requirement for libraries to develop these services economically and operate them efficiently.

The presentation aims to review the present tendencies of information supply in the libraries demonstrating the efforts and concepts of the National Szchnyi Library.
