Incidentally, the full-text of the Hitchhiker’s Guide to the Galaxy is available. (Note: you can’t click the links on the site. You’ll have to modify the URLs a bit.) More hitchhiking to keep you busy.
Full-text of the Hitchhikers Guide to the Galaxy
I found the full text of the Hitchhiker's Guide to the Galaxy online. You'll need to manually tweak some URLs to navigate the site, but it's a great resource alongside other Douglas Adams literary links.
