This is a famous textbook on logic but I didn’t know that when I bought it…
I found it on a shelf of withdrawn-from-lending books in a public library somewhere in Humberside (almost certainly the main public library in Hull but I’ve a vague memory it was somewhere more weird than that).
To be honest I just thought it looked cool with its green cover and minimal title.
It cost 25 pence and I bought it in 1989 it seems. The cut out page was done by the library when they removed the record of when it had been lent out.
This is my second favourite withdrawn library book that I own. It is also a really decent text book on logic.
