I cannot see the triangle from here (Germany). There are fulltext
links on the right side instead. Unfortunately most IR contents are
only in the Google websearch not in Google scholar.
Let me say first that 100+ of my publications as historian are gratis
OA, including 4 of my 5 books. Most articles are deposited in IRs
(Freiburg, Heidelberg, Frankfurt, etc.).
On the first page there are 7 articles on the right side flagging free
full texts. If you follow the links on the left side you will find
additional 18 full texts.
