Our project is work in progress, if only because private museums keep opening up and closing as well. We moreover see our project as a collaborative enterprise: on our own, it is difficult to keep track of all developments across the globe. Therefore, your participation in and contribution to this project are more than welcome. If you happen to know of a private museum which does not appear on the map, or if you have reasons to believe that any of the information regarding museums on the map is incorrect or out of date, please let us know through the contact form below, or mail us directly on email@example.com. If you want to understand better how we define what a private museum is, please check the appendix of our report.
