Some years ago I was asked by a fella to go look at an aircraft that was for sale. He just couldn't get there at that time. I knew the aircraft and the owner (who had passed away). First thing I went for was the logbook. There was not a single entry in it for the last 15 years and no mention of the three prop strikes I personally knew it had experienced. Two tip onto nose events, and one fence hit. The aircraft had been flying occasionally in those 15 years, and had been flown from location A to location B about a year before I saw it again. Conveyed that info to the interested buyer, he ended up buying it as a grubby and tired airframe with a worthless engine and no genuine maintenance records. He had a new engine built and professionally installed, and lots of other work done to get it up to usable level again.
Moral of the story is: Logbooks only reveal what is put into them, which may not be everything that has happened to the aircraft.
