Where does the peer review indicator come from?
Answer
According to Ex Libris documentation:
"The relevant Alma CZ records for journals have been enriched with a peer review indicator, which is based on Ulrich's (500 $a Refereed/Peer-reviewed) setting."
The Open Access indicator is also coming from Ulrich's.
There's an August 2019 Idea Exchange entry about making the peer review indicator more accurate:
https://ideas.exlibrisgroup.com/forums/308176-primo/suggestions/38315248-making-the-peer-reviewed-icon-more-accurate The problem with the current peer review notation is that it's applying to anything from the peer reviewed journal, including book reviews, editorials, etc.
Another problem reported on the Primo-L listserv, is that journals that are not "refereed/peer-reviewed" are getting the indicator. For example, one title mentioned is: The journal of housing and community development. In Primo, the journal has the peer-reviewed indicator. However, in Ulrich's there is no indication this title is peer-reviewed.
Ex Libris is relying on the vendor to let them know whether to include the Ulrich's (500 $a Refereed/Peer-reviewed) setting. This information may not always be accurate.
Also, some people are annoyed that Ex Libris wants libraries to report each time they come across a title that has an inaccurate indicator (vs. fixing the problem system wide).
