There is talk about roots and branches in Covenants, there are book stats given, e.g. in L&L or RoP: Divine - but is there a file or forum entry that provides a full list of these works?
If not, do the forum gods (Michelle) allow such a collection (as a forum thread or - even better - a pdf on the Atlas Games site - or does such a project infringe on something copy-rightish?
I do not myself have all the Ars Magica supplements, but I'd be willing to participate in such a project.
