Philosophy is also a belief system, but one that is not necessarily predicated on belief in the supernatural.
Some belief systems have books, some do not, but they have in common the fact that they are unprovable, thus belief based.

So we have competing belief systems in the atheism vs religion debate. That there is no codified, official belief save for the various books written by the various "professional atheists" allows you to insist to yourself that atheism is not a philosophy.
But if we use this definition of philosophy:

It seems to me that you are confusing terms here.
