Kessinger Publishing has reprinted much of Thorndike's work: but (unless I've misinterpreted things) their modern print-on-demand reprints seem to be about £25 for 200-ish page segments, whereas copies of the original eight volumes (published in pairs in 1923, 1934, 1941, and 1958, and each volume of which is 600-700 pages) go second hand for £30 or so.
Even something like Thorndike's "History of Medieval Europe" can be picked up for £5 or less, while the Kessinger POD reprint is more than £20. Bizarre economics!
As with David Kahn, everyone namechecks Thorndike: but few have read all 6,000-odd pages of the HoMaES series. I'll admit it: though to date I've only ever read sections as required, one day I'll read the whole lot... I hope!
All in all, there really doesn't (unless you know better?) seem to be a Thorndike 2.0, a decent modern alternative to HoMaES in (say) only 1,500 pages or less. So even 50 years on from Vols VII and VIII, the new Thorndike is still Thorndike!
