 === Google Scholar (or some other site) locked me out after using Zotero to save items. What happened? ===
-Particularly zealous Zotero users will occasionally push the limits of what Google Scholar, or any other Zotero-compatible database, wants an individual to access in a given period of time, and you may see a message like the following:
+When saving multiple items, Zotero users will occasionally push the limits of what Google Scholar, or any other Zotero-compatible database (e.g., ProQuest), wants an individual to access in a given period of time. When this happens, saving to Zotero may fail, and when browsing the site you may start seeing CAPTCHAs or messages about making automated requests.
-//"Query limit reached"//
+If you need to import more than a few items at once, it's better to first save the items to Google Scholar's [[https://scholar.google.com/intl/en/scholar/help.html#library|"My Library"]] feature, export items en masse as a BibTeX file from the My Library view, and then import the BibTeX file into Zotero. Other sites may have similar features that allow exporting a collection of items. You can also simply click through to the article page and save from there rather than saving from the search results page.
-//"We're sorry but your computer or network may be sending automated queries. To protect our users, we can't process your request right now."//
+The [[https://github.com/beloglazov/zotero-scholar-citations|Google Scholar Citations for Zotero]] plugin can also send sufficient numbers of queries to cause Google Scholar to lock out Zotero.
-This tends to happen if one tries to import 50-100 items from Google Scholar either all at once or in rapid succession.
+=== How can I restore my access to the site? ===
-=== But this happened to me when I was using Zotero's [[:retrieve PDF metadata|Retrieve PDF Metadata]] function? ===
+Sometimes a site will request a CAPTCHA verification. In this case, complete the verification test to restore access. Otherwise, in general, the site will restore your access within a few hours. You may be able to access the site using a different web browser in the interim.
-The Retrieve %%PDF%% Metadata function also uses Google Scholar, so, if you want to auto-detect metadata for several dozen PDFs, try doing them in smaller batches with a few minutes in between each set.
-=== How can I restore my access to the site? ===
-In general, the site will restore your access within a few hours. You may be able to access the site using a different web browser in the interim.
+If you're still able to access the site in your browser but not able to save to Zotero, as a temporary solution you may be able to save to BibTeX or RIS, as explained above, and import the file into Zotero.
