search polyglot chess books for chess frontend (blind user)

[qwertologe]

Hello,

i develop a chess frontend for blind people under Linux.
It has an optimized character interface and can speak.
Minimum requirement is a normal console/terminal.
Supported are UCI-engines, since i use the polyglot adapter.
It is developed as a Ruby gem and will be released under GPL v3.

I search polyglot opening books and like to ask you, if you can send me
one or the download link together with a few words which confirm that you
own the rights and that you give me the permission to release it together with
my gem.
If you send a book/link, i will put your answer into the gem for
documentation purposes.

It would be nice if you can give me some information about the book(s):

- author name
- year
- average ELO
- average halfmoves
- halfmoves
- purpose of the book
- best used with which engine(s)
- recommended name
- recommended short name

I will shorten the information to about one line for each book.
The information will be available in the frontend.

Thank you for your effort.

Kind regards
Michael Arlt
