Thought that this could potentially prove useful to someone someday. Person obviously seems to have done a lot of work.

Hi Project Gutenberg Activist,

I am a student in www.townshend.cz and downloaded your 10K Gutenberg-4.2GB-DVD.iso (http://www.gutenberg.org/dirs/1/0/8/0/10802/10802-rar/) and wanted to

thank you very much for this wonderful organized job!

All the old books that might have been lost are digitized and free for everyone! (I am still waiting for Aldous Huxley's - "brave new world" though ;-)) Currently I try to make my own ebook-library. got 2 DVDs full of ebooks!!!! WAHOOO! ;-)

I hand them around as much as I can to distribute the wealth of knowledge.

The Human Genome Project was included in the .iso although the homepage said it was not. (it's an extry 400MB of text not really interesting TCGAAGTCA-

Sequences)

Anyways... managed to re-pack the textfiles (without HGP) from 7.28GB to 2,36 GB (32%). (with 1% CRC) (Still 4CDs! ;-() Packed every folder in one .rar (so you have ETEXT00.rar ETEXT01.rar...)

Even thighter was packing the whole thing into 4x 700MB.rar and 1x200MB file 2.25GB (30%). (without CRC but including human genome project!)

Thought that is interesting for you. (webspace, download-traffic and all)

Know why? Packing a iso does not compress well, nor does packing .zip files with .rar.

What I did is the following:
