The Report Series A of the Department of Computer Science is published as two versions, online (ISSN 1795-9195) and printed (ISSN 0787-6416). Until year 1999 the reports were published as printed. Since year 2000 the reports have been mostly published online only, and printed copies heve been taken just for library archives. Nevertheless, some reports like proceedings (e.g., A/2003/1) may occasionally be printed, too. Most of the reports that were printed before 2000 are also included in the online version of Report Series A.
