Each Zotero user is given 300 MB of free cloud Zotero File Storage. Larger storage plans are available for purchase. Visit for more information.

If you would like to use Caltech Box instead of Zotero for storage, follow these steps to set it up:

  1. Log into Caltech Box using a web browser and your access.caltech credentials:
  2. Once logged in, click your name at the top right of the screen, then click on "Account Settings".
  3. Under "Account Settings", find "Create External Password" at the bottom of the page.
  4. Click "Edit password", enter a new password and verify it, then click "Save".
  5. Log out of Caltech Box (if desired - you do not need to be logged into Caltech Box to use Zotero Sync with it).
  6. Start Zotero Desktop.
  7. Navigate to the "Preferences" menu and then the "Sync" tab.
  8. Under "File Syncing", check the box next to "Sync attachments in My Library using" and select "WebDAV" from the drop-down menu next to that.
  9. Next to "URL:", select "https://" and enter the following into the field: "".
  10. For "Username:" enter the email address that is associated with your Caltech Box account.
  11. For "Password:" enter the External Password that you created in Step 4 above.
  12. Click Enter (NOT "Verify Server").
  13. If Zotero can successfully communicate with your Caltech Box account, you should see a message saying "Server configuration verified" and "File sync is successfully set up."
  14. At this point, if you tell Zotero to sync your library, it should start uploading and syncing with your Caltech Box account.
  15. To verify that syncing is taking place, log into your Caltech Box account and look for the Zotero folder. There should be a list of files in there. Do not touch with them.
