The goal of this paper is to offer a selection of basic information sources of interest for the experts of the Catalan literature, available in Internet. For the selection it has been taken into account the quality of the contents of the chosen works: their completeness, rigor, updating, etc. The criteria of inclusion of the works has been quite restrictive: for example, web pages devoted to authors have not been picked up even though there are excellent information sources in this area. The person who becomes interested in identifying resources dedicated to an author in particular will find the pertinent links from the first section of the work: encyclopedic works and portals.
