Hi,
I am at an academic library and at this time our games are in-house use only for students. We also let official campus groups use the games for teaching and events. Our concern is that our students might use our games as a way to replace any of their lost pieces if they are allowed to take them home. We don't count pieces each time a game is returned.
Participating in International Games Day is a great way to start a collection! Plus, I have had great success each year just asking for donations from video and board game companies. If you have a program, many companies are happy to donate demo games for play.
We have just started partnering with a few board game groups as well. We provide a space and they bring boxes of their games. This is a good way to learn new games and see what would be worth buying for your library.
GameRT does not lend its games through ILL at this time. If you do find a library that lends games, please let us know.
