ABSTRACT
This inventory study shows that a new type of repository is emerging. It is non-institutional and only to a certain degree research based. These thematic repositories need further analysis as a kind-of-their-own in order to establish the nature of their content and relationship and the specific place they may have in the repository landscape. In this chapter a preliminary inventory is made to get a first impression. In the years to come this type of repository undoubtedly will need more attention.
