BeOS related books - developers book too

Hello,

I think it worth a new topic stating what BeOS books are available and how usefull are they. I know that in the Haiku website one can find in the DEVELOP/RESOURCES http://haiku-os.org/develop.php section a lot of usefull information and some books on-line version. So for example : if anybody wanted to buy the "Programming the Be Operatin System" book here also can find a free full version. I think it is a good start to anyone who would like to write an application to Haiku/BeOS.

So if you have anything to report regarding an older BeOS related book or if there will be something new regarding Haiku I think this topic will be a good place to report and talk about.

I would also have a question to those people who have the original "Be Developer's Guide" and/or "Be Advanced Topics" books. How usefull nowdays these books. Is the "Be Book" covers everything from these older book or do they contains still useable things? Are they for beginners or for "real programmers"? I am considering to buying them but if they are not anymore relevant to BeOS 5 then I will try to manage with the Be Book. Thank you for your comments.
