I'm not sure, but if pressed, Linder could always claim he wasn't doing it for monetary gain,
and thus tie you up in court for years.
Once again, I did some Internet research, perusing various legal sites. If I understood correctly, it is still not legal to record copyrighted books even if you are not doing it for profit. Permission must first be granted by the copyright owner. So unless the National Alliance has done so, it appears to be illegal. By all accounts, Alex Linder is violating the law.
