As I ordered another book recommended by an Amazon book club and entered another early Christian writings book request on Logos, it occurred to me that Logos could merge the two activities and make money. What if Logos were to offer on a monthly basis a short (think Popular Patristics series book size) book with study questions (AI generated but human reviewed) to people who signed up for the "subscription". These should be of interest across all denomination e.g. early Christian writings or historical documents. The books could be from standard publishers or from Lexham Press - the latter giving scholars in less popular fields an opportunity to share their work. I would like to think that there could be a Bible text/methods subscription as well but I am unaware of a book series that would serve as an example.
