Small Library Organizer Pro v1.8 includes separate Check In/Out module.

Check In/Out module is a stand-alone application. Check In/Out Transaction module allows to process loan / return transactions without launching library software. Your library databases are protected from unwanted modifications and users.

If you have older version of the Small Library Software you can download the following file:
checkinout.zip
Decompress the file in the library main folder.
