I just got an email from Barnes & Noble. They're running their free classics promotion again, and this time B&N Members can get 100 free public domain titles if you buy a Nook. Last time they had a promotion like this I ridiculed B&N for giving away books they didn't own. TBF, that's nnot what they're doing.
I have a couple of B&N's pd titles on my various Nook apps, and I looked them over before posting. The ebooks that they give away are not your ordinary grab-from-Gutenberg ebooks. They've been enhanced with endnotes, footnotes, introductions, and related readings.
The problem here is that B&N keep failing to convey the value they've added to these titles. Even when they did mention it in the press release, the details were buried near the end. Few read that far into a press release; I don't because I have trouble controlling the urge to vomit (after you read your 40th or so press release you'll understand how I feel).
Anyway, i think you should try one of the B&N freebies before you disregard them.
