Symposia is a used bookstore in Hoboken. They also have a bike rental (for free) thing. The books are incredibly priced, I have no idea how they stay in business. The also have internet access and have exhibits of local artists and things. It’s a hippy sort of place that is great. If you have some old book give them a new home, they accept donations and provide tax receipts for tax time deductions. Much better then a book Mega-Store, staff is peculiar but very nice.
