Yes, but there are a few conditions. 

We want to keep the rentals in good condition so they can pass through the hands of as many students as possible. Here's how we treat markings:

  • Highlighting - Highlighting is generally fine as long as it isn't too excessive.
  • Writing - We kindly ask that you refrain from writing in rented books. (But a few stray marks shouldn't be a problem.)

If a return rental is marked on or damaged to the extent that we are no longer able to sell it, the book will be recycled and you will be charged the purchase cost.
