CheckItOut is a Google Forms add-on.

This will create one question for items that are IN and another that are OUT. Items will be moved between the questions on submit.

Used for checking in and out items, this add-on will create a question set or multiple sets. One question is for items that are IN and another for items that are OUT. Questions can be Multiple-Choice, List or Check-boxes. When someone fills out the form selected items will be moved between the two questions. This allows a for a very easy check in/out form. This is great for signing out equipment from the library, or even classroom camera’s. Other questions can be added to the question sets so that you can capture any information that you would like.
