Setup a monthly $5 donation. It's not much, but I know how valuable the archive is... they're doing the work the library of congress SHOULD be doing.
How valuable is it?
I don't remember the exact formula, but it was similar Shannon's equation. Basically, the more valuable information is, the larger the change it affects in the probably of what an organisms next behavioral state is. So, if information signaling didn't change the behavior of another organism, it wasn't considered communication.
