One of the goals of the MeDoc project is to make computer science literature, e.g. Technical Reports and project and master theses of different authors and institutions available online through a single user interface. Therefore, we evaluated existing Technical Report servers as to their suitability as a basis for an electronic library and chose NCSTRL. The Networked Computer Science Technical Reports Library (NCSTRL) is a world-wide, distributed collection of computer science Technical Reports and other relevant materials. It is a well established system, but there are some deficiencies that need to be taken into account. This paper presents two different enhancements to the NCSTRL system to overcome those deficiencies. The first adapts NCSTRL to support not only the publication of Technical Reports but of other grey literature like course materials and theses as well. The second extension allows for the utilization of NCSTRL as a general tool for the online-publication of and search for electronic documents in multiple collections.
