Pac non peano

Something being written that these references are for: a paper, a thesis, a course.

Sources for a project on arithmetic without Peano's axioms: Grassmann's 1861 Lehrbuch which preceded them, commentary on Peano and his school rather than his own papers, the consistency literature, and the parallel-postulate and non-Euclidean writings as the older case of doing without an axiom. Membership is by citation, so a work here is one the project uses and not necessarily one it agrees with.
