You might take a bunch of pics of the books' spines and put up somewhere, so people can see what they might want to buy. If I were you, I'd also say that shipping is at buyer's expense and requires a minimum of $___ purchase (like $200). This will be work, but if they get enough sales to book lovers, it may net more than the per-pound offer a used bookstore will pay.

I've sold a lot of books to Powells Books - they take maybe 1/10th of the books and reject the rest, you end up carting 9/10th to Goodwill. "Newish books" tend not to get accepted. For what they accept, they pay at best 1/3 of the price they might be able to re-sell the book for. The point is, you can bring in six boxes of books and leave with $30 and five books.
