And yet that need exists.
You need approval from Eugene Nalimov and Andrew Kadatch.

Books are a compilation of facts.  They are copyrightable.

The relevant copyright notices:

/*                                                                      */

They cannot be used without permission.  They cannot be sold without permission.
There are some kind souls that have allowed free access to EGTB files.  For use
with a program that already has permission, there is nothing wrong with that.
To download them and sell them is DEFINITELY illegal.

IMO-YMMV.

I'm not a lawyer either.
