Step 3: Get better results

  • For best results, ensure you are visiting reputable journal websites or databases. Unpaywall works best with common publishers.
  • If you encounter a paper that is not available, try searching for the title in Google Scholar to see if other open access options exist.
  • Make sure your browser is up to date to avoid compatibility issues with the extension.

Pro tip

To save time, use the Unpaywall icon as a bookmarklet in your bookmarks bar. This allows you to quickly check for open access versions without needing to navigate away from your current page.

Common mistake to avoid

Don't forget to check the icon's colour. If it’s grey, it means there’s no open access version found. Always look for the green icon for free access.
