The Zotero Connector does not detect specific types of legal documents in Westlaw Edge or in Lexis+.
For example, let's say you wanted to add the case R v Chaulk to your Zotero Library from Westlaw Edge. The image below demonstrates how the Zotero Connector grabs a snapshot of the Westlaw Edge webpage, but it does not recognize that the webpage contains a case, nor does it pick up the citation information for the case.
You can fix this by going into the record in your Zotero library and changing the Item Type from 'Web Page' to 'Case', as shown below.
Next, you will need to manually fill in the required fields with the correct case citation information.
