They differ in one white space at the ending at the end of the last_name as described in the old forum article. Both links lead to the very same page listing the same articles. Other than described in the old thread, I can not repair this by removing the white space in the article metadata because there is none. I have no idea where to find this white space actually, not even in the database:
select concat('|', last_name, '|') from authors where last_name like 'Eck%';
The authors table has an entry per author per article – if an author is credited for two different articles, they’ll have two different entries. This allows author metadata to be unique per article, so e.g. authors whose names, institutions, etc. change won’t causes to already-published metadata.
That makes it hard to disambiguate and properly list articles with their holdings. Our plans for this are primarily focused on ORCIDs, and we’ll be working in OJS 3.x to refine the connectivity with ORCID. However, we’re unlikely to make major changes to OJS 2.4.x at this point.

Thank you Alec for the reply. I understand that. But as you can see in the query results above, there is no version of the name which includes a whitespace at the end (to make this visible I put pipes in the and and beginning) - so why does it still produce two author links, one with withe space and one without?
