I have an idea for a project but it will require being able to create Kindle books on the fly on the server and preferably in .net.
I haven\'t found any libraries to do
You can try with Calibre. It has support for .mobi file format.
If you are already able to create an EPUB file, use the Calibre command line tool ebook-convert.exe:
ebook-convert.exe c:\file.epub c:\file.mobi --output-profile=kindle
As an alternative, you can produce PDF files, as they are supported by Kindle.
I am doing something similar. One way to go about it is:
As far as creating things like the Table of Contents, starting chapters on a new page, and other things that can be accomplished in a Kindle eBook, you may want to read a kindle formatting guide, such as the Amazon Kindle Publishing Guidelines.
Also, you may want to read a book by a third party on the subject. I have personally read Kindle Formatting by Joshua Tallent and How to Format Perfect Kindle Books by Steven Lewis and they both contain the information needed for properly formatting a kindle book using an HTML file. You can obtain both books from Amazon. The Tallent and Lewis books are aimed at authors that may have never created an HTML file by hand and guide you thru the process.
