What it does

Written by AI from the README

Adds journal-ranking columns from easyScholar: JCR quartile, CAS partition, impact factor, EI, and Chinese core lists such as CSCD and the Peking and Nanjing lists. Also journal abbreviations, metadata refresh and author/title fix-ups. Needs a free easyScholar key.

Researchers in China constantly need a journal's tier when choosing what to read or where to publish. Green Frog shows it for every item instead of requiring a separate lookup.

What you'll need

We haven't detected any setup requirements. That isn't the same as none: check the developer's README.

Forks and alternatives

1 other plugin uses the same ID as this one. Every Zotero plugin carries an ID, a name tag Zotero uses to tell plugins apart. These 2 plugins carry the same one, because people copied Green Frog to make their own versions and kept its ID.Show what this means
  • You can only have one. Zotero sees them as the same plugin.
  • Installing another replaces it. If you install one of the others, it takes this one's place.
  • Check what you install. Several share this plugin's name, so make sure the file comes from the one you meant.
