ISBNs are 10 or 13 digit numbers that identify a specific edition of a specific textbook. Go to your university website or class syllabus and find the ISBN numbers of your required books! We'll make it easy to compare prices online! Simply search for these numbers in the box above and SlugBooks will do the rest!

Pro-tip: you can search for multiple ISBNs at the same time by entering a comma separated list of ISBNs into the bar above! (for example: "9781449410247, 9781449427702, 9781449401160")

To compare multiple books at the same time, just enter a list of ISBNs separated by commas or spaces (like a boss!). For example, searching for "9780393347258,9780451205766,9780312361815" will return a price comparison for all three books.

If you prefer searching for one book at a time, we store your most recent book searches in the sidebar, so you'll still only be one click away. No need to copy/paste the same ISBN twice!

Due to some pretty unfortunate circumstances, we are not offering book search by school/course at this time. Fear not brave SlugBookster: you'll save more money than ever using our book search, simply enter the your booklist ISBNs above!

If you have fond memories of course search or need to vent about it's disappearance, please email [email protected].

Just like we compare buying and rental options, we also compare sellback options. Most of the same websites that sell books to students are also interested in buying books. When you search for a book by ISBN, we provide a list of quotes. If you decide to sell your book to one of the sites, they will provide you free shipping labels. After you print the label, simply drop the book in the mail with the shipping label and you'll have that sweet sweet cash (or Amazon store credit if you sold through Amazon Trade-in) before you know it!

Typically the shipping label provided is trackable - give it two-three weeks after the book has been delivered to start looking for your check in the mail (or if you did Amazon trade-in, your Amazon.com store credit). You can also check with the website you sold the book to.
