Hi, Thomas.

I am talking about publishing for e-readers. In the USA, college students are using e-readers for most readings. Therefore, it would be interesting to have a Visual Prolog book for e-readers. I am thinking in something like Haskell for the Real World, Kindle edition. There is also a Kindle edition of Elizabeth Castro's books. I would like to write a Kindle edition of a Visual Prolog book. Of course, we would need a Nook edition too.

Hi, Eduardo.

My comment was related to your first sentence:
Eduardo Costa wrote:Visual Prolog users need at least one book published through normal channels, i.e., publishers like IGI, Prentice Hall, Amazon, etc.
I did realize that you also talk about e-books. I do how ever not have very limited knowledge about e-books and none about e-book publishing.

For what it's worth, my publisher supports the E-Book option and I tried that with my first book on Golf Etiquette (, which is available as a Paperback as well as E-Book. I have mixed emotions about the E-Book option though, as they are created with Adobe Acrobat with permissions set so they can not be modified or printed; however, I couldn't find any protections against coping, which seems like a big open door for what some refer to as bootleg copies. Maybe E-Readers or Kindleware are different. Good luck if you go down that path.

Note: I liked your 'Visual Prolog for Tyros'. Maybe you'll like my 'A Guide to Artificial Intelligence with Visual Prolog'.

Best Wishes,
Randall Scott

Hi Eduardo, Thomas and Randy,

I happened to buy a Kindle and did some research on getting free books for it. The Kindle can be used to read PDF-files, but the quality is not great (to be friendly) A second option is to translate a book into Mobi-pocket format. The Kindle format seems to be slightly different, but it reads Mobi-format without trouble. There is a free program, Calibre, that can be used to transform different e-book formats.

There is also a (free) Amazon service to translate some formats into Kindle format. But as the Kindle is capable of reading PDF, they no longer translate PDF into Kindle format.

When using Calibre, the result is fairly good. I think it is possible to write a Prolog book and publish it as an ebook. To see how figures are processed, I had my Beginner's Guide reformatted by Amazon and it turned out to be readable. Some figures went wrong, but I guess that with some editing, these problems can be overcome.

And I think that if we refrain from royalties, then Amazon will be willing to publish the book for free. If necessary I'll get an ISBN and we'll publish it via several internet bookshops.

Kind regards,
Thomas de Boer

In my previous message I used words like "transform"and "translate". I think I should have used "convert".
