My aunt died a few years ago and left an entire apartment full of books. We just don't have the space for them. Most of these are from the 1970's and are old enough that ISBNs aren't listed on the books. Most have some wear. Any of these are free with an order from my shelf:
Three Short Novels by Fyodor Dostoyevsky: Notes from the Underground, Poor People, and The Friend of the Family. Paperback, slight blue pen marks alongside passages.
The Inheritors by William Golding: Slightly yellowed pages from age, otherwise in good condition. Paperback.
Studs Lonigan by James T. Farrell: Wear on spine, one black mark on bottom of book. Paperback.
Made in Canada: New Poems of the Seventies. Poems from Margaret Atwood, Michael Ondaatje, and many others. Paperback with blue pen mark alongside some passages.
The Mayor of Casterbridge by Thomas Hardy: Paperback, blue pen marks alongside passages.
Sanctuary by William Faulkner and Sartoris by William Faulkner. Both are old and have yellowed pages, but are otherwise in great condition.
