For the past few years, I've been looking now and again for Nightshade (1857), a novel by Irish anti-Catholic campaigner William Johnston. There are a scant few copies in various and sundry research libraries, the closest of them at Boston College, and I've never seen one for sale. Well, not until now, anyway. Here we have one of these anonymous-looking POD books of somewhat baffling provenance, sold by what appears to be an e-book club (also with a somewhat anonymous-looking home page). A number of these POD companies are simply scraping content from GoogleBooks, Project Gutenberg, and even Wikipedia, but Nightshade doesn't exist in full text on any free electronic archive. So where, I wonder, did the OCR come from? Does GoogleBooks sell otherwise inaccessible content to POD publishers? Are there legions of elves sneaking into research libraries to scan rare books?
ETA: Out of curiousity, I decided to see if I could download the PDF version. Because they wanted my money, right? Well, no--"Sorry, we can't provide this edition to someone in your country for copyright or other reasons." Let me see if I understand this correctly: you can't sell me a $9.99 PDF of an OOC book for copyright reasons, but you can sell me a $36+ paperback copy? How...interesting.
