What can I say? When you quote the classics you had better be ready to give credit and provide Further Reading lists.
The title "Mostly Harmless" is from Douglas Addams' creation "The Hitch-hiker's Guide to the Galaxy" - a radio show that became a TV series, a horde of books, a computer game... and heaven knows what else..
Now, my connection to the story is only that of someone with fond memories of first hearing them, reading them, seeing them etc (and occasionally quoting them) - but some people have taken their enthusiasm a lot further.
If you want to pursue this subject more, here are some very good websites where you can immerse yourself in The Guide and follow a huge number of links.....
Apparently the entire entry in The Guide for Earth had originally been "Harmless", but in the much-enlarged next edition this was revised to.... well, I'm sure you get the point.
A HUGE links list - but also have a look at the rest of the site - it's still growing...
Welcome to the hotel. - This is the site of the nice people who built the links list above. Drop in and say hello.
