Гледам, че неща като лицензи май не те притесняват 
Това е от сайта на Брус Екел (за TIJ и TICPP):
The electronic version of the book will continue to be free. You have permission to print a copy of the book for your own use, and to distribute the unmodified electronic version(s).
If you like the book, please:
1. Recommend it to your friends.
2. Create links to this site from your web page or mirror this page.
3. Report any errors or problems you find.
4. Consider buying a copy of the printed book - it's probably cheaper than the toner cartridge you'll use up printing it yourself. However, if it works well enough for you as an electronic document, great!
5. Consider buying a CD Rom or coming to one of my seminars.
