I don't believe the Bible is a historical work. It has its place in history, certainly, but a lot of material has been compiled from other sources that, while probably having their own agendas as much as the Bible, are not steeped in religious intent. Furthermore, not one of the canonized gospels was written prior to a generation after the death/disappearance of Jesus, and each was written in order to make a religious statement, not a historical one.
With the exception of a few of the Greek and Roman writers, and of course modern historians, that's pretty much always been the case. That doesn't mean that we don't consider heiroglyphics on the walls of Egyptian tombs historical, or the "national archives" of Hattusas historical, or any number of other works that were, in many cases, composed under even more dubious historical circumstances than the Bible.
As I said earlier, regardless of one's opinion of it, the Bible is, and likely always will be, the best and most detailed historical document of the area and the time period.
As barsoomcore said, that doesn't mean it necessarily jives completely with other sources we do have, but nobody's denying that the various sections of the Bible were written with an agenda. Also, as you point out, the Bible isn't so much a "book" as it is a latter compendium of other writings, many of which the time of writing and the author are not well known. In addition to that, the influence of later editors is difficult to determine.
None of that changes the fact that the Bible is, and likely always will be, the best and most detailed historical document of the area and the time period. You just have to go into things with your eyes wide open about the limitations inherent in it as a historical work. But, as I said, they aren't really unique or even overpowering limitations compared to many other historical works that are also widely accepted.
