This is more of an MPSIMS, but it deals with “literature.”
When I was in high school a quarter century ago, a classmate lent me a book of his called “Sir MacHinery” (or “Sir Machinery”) by a chap named McGowan.
I seem to recall it as having been written for a younger audience, but found it enhoyable all the same.
A quarter century later. . .
I thought this would be a good book for my growing number of nieces and nephews, and sought a copy. Alas, it is long out of print.
But that was not the discouraging part. . .
I took a quick look at Ebay, and one had shown up there in the past month or so–selling for about $100!
YIKES!
So I checked out some used book search engines (Bibliofind, Advanced Book Exchange, etc.)–The Ebay price was a bargain in comparison!
Makes me wish I had purchased a dozen or so copies back then–even though I would not have had the money for even one.
