We have recently merged another troop into ours and therefore inherited a number of binders full of old material, and I think this only goes back about ten years. Our parent committee has wisely granted permission to transfer all of this data to a .PDF format to allow for storage on computer disk.
Granted, the parent that indicated my suggestion of saving storage space by keeping them on disk would not be practical would have been given the practical pleasure of finding a place in their own home for storing all of these binders
I definately see the need for keeping old data, even for a long period of time, but I can't see keeping hard copies of every bottle drive flier since 1994 (the only change each year is the date

) Advancement records, on the other hand will be stored electronically, but also maintain a hard copy during the entire time that any boy listed on that form is still under age 18.
Just my two cents
