Free eBooks and interesting ways to use text

Many books are in the public domain now and can be found online for free. Here's a good site that even has books in different formats like Kindle as well as plain text:

Apart from reading a good story you can also use such text in other ways. For example, once I was writing a guide to creating newsletters in MS Publisher and needed to show a page with text flowing through columns. Typing lots of blah blah blah would've been possible by copy/paste but it would've looked boring. Instead I pasted in a few paragraphs of text from The Hound of the Baskervilles!

Recently I've done some software testing and having large amounts of text available to copy/paste has been useful too. If you want to count text characters I would recommend using Notepad++ as it is accurate, MS Word isn't for example.
