Another instalment in my continuing not-very-subtle campaign to bankrupt my readers by recommending unmissable books! I’ve just picked up from the CUP Bookshop a copy of John P. Burgess’s new Mathematics, Models and Modality. It collects fourteen of his papers (mostly published before, though in very scattered places), with a useful introduction. Well worth having, and certainly your library should get a copy.
(But, having whet your appetite, I can perhaps save you some cash by noting that the new introduction and several papers are actually downloadable from Burgess’s website, and most other papers you should be able to get online via your university’s subscription to JSTOR.)
