Hello everyone, I've been having some trouble trying to use the 'library lookup' button for searches using Open Worldcat. I used to be able to do this, as far as I can recall, by default. Recently, however, Zotero has been prompting me to select an OpenURL resolver from the menu for the 'library lookup' button to use [popup saying: You must choose an OpenURL resolver from the Advanced pane of the Zotero preferences.].
Convenient though this may be, for my work I simply want Zotero to search all of Worldcat (as one would do by going to https://worldcat.org/ and entering the search terms there), rather than through a specific institutional proxy. Is this still possible? I couldn't figure it out. Leaving the OpenURL field in preferences empty results in the prompt to select one, and I couldn't find any URL to enter for 'Open Worldcat'.
I'm sorry if it's already posted somewhere, I've been looking through forums and the web, but can't seem to find a solution anywhere. I'll appreciate any advice!
