Worthless books include most fiction, self-help, and business
management theory.

However, many technical books are valuable and can be sold. It can be
hard to tell which are valuable and which are not, without extensive
research.

Three years ago, I bought four crates of Hyster forklift service
manuals, at an auction of a failed Hyster dealership, for $50 for all
four crates (plus buyer premium). To date, I sold 290 of them, and got
paid $22,349. I still have 236 of them, at the asking price of
$18,961, and I surmise that most of those will never be sold due to
lack of demand.

That's 77 dollars apiece for the first batch. Are those service manuals that rare and valuable?


They are not rare. I did some research after I bought them, and found
out that they could be bought for $300 each from Hyster.

They are, however, valuable, in the sense that people needing to repair
forklifts, or some people who just buy a new forklift, want to buy a
maintenance/repair manual.

As far as I am concerned, we fix a lot of forklifts and do not use
such manuals all that much. Old forklifts are relatively simple. We
also know a gentleman named Jimmy who is a walking forklift manual.
