We were able to develop an add-on for libraries that would like to incorporate SEAL into their ILLiad procedures. Our Youtube video "Install ILLiad Add-on" provides step-by-step instructions on downloading and installing the add-on. The manual and additional Youtube videos detail managing SEAL borrowing and lending requests in ILLiad.
Note: in some instances, you might need to re-install the add-on files after updating to a new version of ILLiad.
