Volunteer-generated errata pages

I picked up a used copy of Quaternions and Rotation Sequences by Jack B. Kuipers for a project I'm starting to work on. The feedback I've seen on the book says it has good content but also has lots of typos. My copy has a fair number of corrections that someone penciled in. Someone on Amazon alluded to an errata page for the book but I've been unable to find it.

This made me wonder more generally: Is there a project to create errata pages? I'm thinking especially of mathematical reference books. I'm not concerned with spelling errors and such, but rather errors in equations that could lead to hours of debugging.

I would be willing to curate and host errata pages for a few books I care about, but it would be better if this were its own site, maybe a Wiki.

I don't want to duplicate someone else's effort. So if there's already a site for community-generated errata pages, I could add a little content there. But if there isn't such a project out there already, maybe someone would like to start one.

[1] Update: Jan Van lent found the errata page. See the first comment. Apparently the changes that were penciled into my book were copied from the author's errata list.
