Repozitar is a unified search tool for Czech open repositories. By default their keyword search only returns records which offer full-text. A nice touch, and it makes one wonder why the English-speaking world’s repository search tools seem to have such trouble offering this simple useful feature.
Repozitar is associated with a searchable nationwide registry of Czech theses, seemingly part of a Masaryk University project to help detect plagiarism in theses and student papers. English abstracts appear to be common in the very detailed record pages.
