The Year of Living Philosophically — previously available only as a Kindle eBook — will be available in paperback on Amazon from Jan 1 next year, published by MTP (Michael Terence Publishing). The eBook version has already been updated with the new cover and revised text.
Publishing a book on Kindle is easy, publishing it as a paperback far less so. As a postscript to the above, I would urge any budding authors who are considering this route to check out MTP. For a very modest sum (and zero royalties) they will liaise with you to produce a professional cover design and fully-formatted interior so that your book is basically indistinguishable from any book produced by a mainstream publisher. They also help with promotion and much else besides. They really are very good.
