Literature databases, scientific journals and communication between researchers on the electronic level are rapidly developing tools in mathematics having high impact on the daily work of mathematicians. They improve the availability of information on all important achievements in mathematics, speed up the publication and communication procedures and lead to enhanced facilities for the preparation and presentation of research in mathematics. The European Mathematical Information Service (EMIS) tries to bundle several of these facilities in a joint offer, to extend them by innovative components and to distribute them in a system of replicators for the benefit of mathematicians worldwide. EMIS has been founded by the European Mathematical Society (EMS) and is run under their supervision with support from the office of Zentralblatt MATH in Berlin. It is based on the voluntary supply of input from sources distributed worldwide. The aim of the lecture is to introduce to the different offers collected in EMIS. A more detailed description will be given for the Electronic Library, offering a variety of freely accessible electronic journals and other electronic publications in mathematics. Another important subject will be the series of RTD projects in mathematics supported by EMS. The descriptions will be complemented by a demonstration of the functionalities of these offers.
