Dominic Giampaolo wrote an excellent book called "Practical File System Design with the Be File System" [PDF available for free!]. This book is actually pretty easy to read and not only talks about BeFS but also about UFS and Linux ext* filesystems.
Dominic used to work at Be and nowadays he is working on Spotlight at Apple. More about Spotlight here.
