THAT is looking in the right direction. If you want to "freeze" the 
books as of a certain state make a copy of the file that is "read only". 
You could use the Julian date in the name you give this file so you can 
tell it apart from "freezes" made at other times.

Can be done with permissions (but that CAN be overridden) or making that 
copy to medium that is "write once/read many" like burning to a DVD..
