Describe the bug
The problem results from articles being published in more than one venue, e.g. a journal or preprint server and in a proceedings, published in the journal or preprint server.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://scholia.toolforge.org/cito/
2. Scroll down to Recent articles with explicit CiTO-annotation
3. See duplicated articles:

Expected behavior
It would be nicer if the articles are shown only once. For example, it could show just one venue it was published in. When people go to the Scholia page for the article, they get to see all venues anyway.
