Early in the 1990s I registered with the ISBN authority to become a publisher and was allocated a block of hundred numbers for my exclusive use. I am still working through these, any that I allocate are registered and become fully available to any bookseller in the world. I publish as The Millind Press.
For some years now I have had a large number of my publications hosted by the very good offices of ISSUU.COM.
This useful website not only carries details of my books but also, without charge, turn them into very readable computer flip books, these may be freely read by anyone going to their website.
