I'd already retrieved two tall stacks of mostly craft-related books (which happened to be near the door) which have been Ebayed (many of them, anyhow; some will be put up again at some point). Now we're working back through the other stacks, largely hardback book club editions of Sixties and Seventies fiction and/or mystery or horror paperbacks.
As far as I can tell, my parents must have belonged to multiple book clubs for twenty years or more and taken the Editor's Choice every month. Never mind a car boot sale; with this lot I could make inroads into stocking a smallish second-hand bookshop. I swear I didn't realise there were nearly this many. Well into three figures and we're not done yet. And these were just the ones they left behind!
And I don't even have kids. I pity the poor sod who winds up trying to triage my book collection some day.
Edited to add: however, I have found a nice hardback (even if book club) copy of Wilbur Smith's first novel among the crud... Ebay, here I come...
