If text books are still relevant, Half Ebay is a great website.
eBay and Craiglist are the two main places that you could sell it online. Depending on the size and cost of shipping then you can decide whether to offer shipping. If you just want it out of your house, you could list it for rent on RentXS
Craigslist
The internet should help you. Craiglist is an example. What you may not need may be the one thing that another person is looking for!
Alternatively connect to someone who could help you on flea market or a garage sale should be helpful.

Instagram, Ebay, Craigslist. The sites will give you all the instructions.
I have some things I want to sell. Like old tv stands and text books for instance. How do I sell online, with the shipping and handling I don't know. But I could use the cash and free up some space.
