Breaking news: David Hume and I just managed to make sure that our paper will be in the public domain when published (by Proceedings of the AMS).
We have been inspired by Saul Schleimer, who has been consistently dedicating his papers to the public domain for quite a while.
And it hasn’t been that difficult! All it took was amending the consent to publish form and replying to an email saying that yes, we really want this.
Apparently “this issue is coming up more frequently”, which is very good.
The reasons why I (we) wanted to do this is explained in the brand new page Science is too valuable not be free.
