**Steps to reproduce**
# Open WorldCat or Zotero
# Search for ISBN 9780198029359
# Open https://cs.wikipedia.org/api/rest_v1/#!/Citation/getCitation (or use Citoid in VE)
# Search for ISBN 9780198029359
**Expected behavior**
The records from WorldCat or Zotero should match what REST or Citoid outputs, right? The records in Zotero seems to be correct, the result from WorldCat has some issues.
**Current behavior**
The REST output (Citoid output) is a mess. There is year in author last name field, there is WorldCat url in e-book url field, there is some english text in numPages field (bad on non-english Wikipedia). What is wrong with this?
**Configuration**
cswiki
**Issue**
I'm not sure what version of Zotero you're using, but unfortunately in translation-server which is what we use, this feature seems to be broken, filed here: https://github.com/zotero/translation-server/issues/79
We currently use worldcat's open search API for this metadata and the results we get are only available in marcxml which is probably where that junk is come from and dublincore which is also pretty messy and not too structured. The results on their website come from a database we don't have access to. I could probably improve it a bit on our end but it might worth working towards fixing zotero instead because they query more databases, or merging the results from both somehow.
