I do agree with you Molly (and others), that the information in the Bible stays the same (at least nowadays, when we have the advantage of millions of copies in print, so we can ascertain if and when someone makes a change to it). But it is we who change.
A while back, I thought of "creating" my own Bible simply by taking the existing Bible and removing from it whatever I thought was either offensive or unnecessary. I stopped shortly after beginning, because I realized that I would be removing the vast majority of the book! Not that I find the majority offensive (though there's quite a large chunk of the minority that I do find offensive), but also passages such as 1 Chronicles 8, 13-27:
and Beriah ahd Shema, who were heads of fathers' households of the inhabitants of aijalon, who put to flight the inhabitants of Gath; and Ahio, Shashnak, and Jeremoth. Zebadiah, Arad, Eder. Michael, Ishpah, and Joha were the sons of Beriah. Zebadiah, Meshullam, Hizki, Heber, Ishmerai, Izliah and Jobab were the sons of Elpaal. Jakim, Zichri, Zabdi, Elienai, Zillethai, Eliel, Adaiah, Beraiah and Shimrath were the sons of Shimel, Ishpan, Eber, Elisel, Abdon, Zichri, Hanan, Hananiah, Elam, Anthothijah, Iphdeiah and Penuel were the sons of Shashak, Shamsheari, Shehariah, Athaliah.... and on it goes.
Certainly nothing offensive there, but why necessary? Why is lineage so important? Why is everything based on "sins of the father?" Why does all of mankind "fall" because Adam and Eve ate the forbidden fruit? Why do Abraham's descendants all benefit because he was a good man and, conversely, why do an evil man's children and cattle have to suffer?
The Bible certainly does make one think. And maybe that's the whole point of it. :-)
