During periods of unusually high usage, Google Scholar may begin asking Cleveland State University patrons to fill out a reCAPTCHA widget to prove they're not robots.  Unfortunately, there is a security bug in this widget that may result in "Invalid domain for site key" errors for patrons who are using the Library's off-campus proxy server.

Please show you're not a robot; ERROR for site owner: Invalid domain for site key

If you run into this error when trying to access full text articles in Google Scholar, there are two ways to work around it:

Workaround #1:  If you have your own personal Google Account, link it to the Library:

  1. Go directly to the un-proxied version of Google Scholar at .
  2. Click the "Sign In" button and log in with your Google account.
  3. From the menu icon (three bars at top left), select "Settings", then "Library Links".
  4. In the Library Links section of the Settings menu, search for "Cleveland State". Select the checkbox next to "Cleveland State Univ - Full text from CSU" then click the "Save" button in the lower right.
  5. Save and return to the GoogleScholar homepage. You now should be able to search Google Scholar without using CSU's off-campus proxy, but still see the "Full text from CSU" links that lead you to our full-text databases.

Workaround #2:  If you don't have a personal Google account, use the Library's temporary search page to bypass the broken reCAPTCHA widget: .

If neither of the above workarounds fixes your Google Scholar access, please contact us at .  Google also usually resets the problematic reCAPTCHA requirement after about 24 hours.
