It is an insult.

socialbib will allow you to accomplish several things. You can save your much-needed cash and get some free textbooks, you can connect with other students in a positive way and you can stick it to “the man.” Really, why should a math book cost you $100 anyway?

For all you know, an old garden rake may be an agreeable swap for some classic literature from another user.For exchanges that may not be an “equal” swap, users can barter an extra amount of cash to make the trade equal. Users can also just offer money and not an object for trade, though people who are looking to do that should probably just check out eBay. Remember, when using any kind of swap site, you will still have to cough up a little dough for shipping.

However, the site only allows “like item trading.” In other words, you can only trade a book for a book and a CD for a CD.
