A sequel of sorts to his perennial collection, Despite Everything,  Add Toner picks up where that volume left off and collects the "highlights" (according to Aaron's introductory essay) of Cometbus issues #44 through #48 – which must be close to everything, as it's 368 pages.  It also contains, an addendum, "8 Out of 10 Days," which is "a conglomeration of books, that for one reason or another were never released," complete with an all new essay contextualizing them.
