HA
Not much help now I am sorry but.
I keep several copies of my log books.
1 Normal copy. However they are a touch out of date. Only a couple of yrs.
2 Command Log Book on my computer.
3 a print out of the computer records and a back up disk of the computer records.
The original log books are like has been said, a personal diary/photo album. The computer version is great for searching hours on type, IF hours all those sort of things and the printed copy is good when you turn up at an interview, nice and neat.
I didn't start keeping a computer record until a couple of yrs back and it took a while to enter, I think around 11,000 hrs but was definitely worth it.
If you have a record of your past flying in any fashion I would get some one in the office to start entering them tomorrow.
I hope they turn up.
Good Luck
