BASE (Bielefeld Academic Search Engine,
indexes OAI metadata and you can search OAI repositories from many
countries (check collections in "advanced search" and the list of content

 In the very recently published 3rd release, BASE also links directly from
single hit records to Google Scholar, in order to re-use the "article citation"
and "versions" functionalities.
