Dominic Giampaolo has posted on his website that since his book, "Practical File System Design with the Be File System" is now out of print, he is making it available to anyone as a downloadable PDF document.

I haven't been able to reach Dominic yet so as to ask why he chose to release the PDF but rest assured, I will try to learn more details about it and let everyone know here.

For anyone who has not purchased a copy of the printed book, and still wishes to read it, download the PDF verson and enjoy.
