What a Boon!
Today we have digital images of game product, both old and new, which can be affordably printed and bound to create physical books through print on demand services. While I do make use of digital images on various electronic devices, my preferred media remains the physical book. I like to hold a book, flip through the pages and even smell the paper and ink. I am "old school". I even prefer to get my daily news by reading a printed newspaper...and get my hands dirty with ink. It seems suiting given what I frequently read in the news.
The combination of availability and price makes print on demand a nice option for the niche consumer and there are many titles available through this service that are not available in any other physical format. I have become a fan of print on demand.
