Library services to businesses: Hungarian electronic information sources

During the last 15 years, the number of business ventures has significantly increased in Hungary, while the quantity of information sources has simultaneously increased too. These changes have brought many advantages, but also a few challenges in the library reference services. Using the electronic format of documents represents the most effective way of delivering customised services rapidly and accurately. The study gives an overview of the most general factors influencing the operational environment of businesses, showing how they are connected to libraries. The second part of the study deals with the content types of the e-documents as information sources, illustrated with a few examples.
