Hi. Good for you. Much easier on your back.
When I went to cooking school (a couple of years ago) pretty much everything was available from one of:
a) the publisher-sometimes they will have a pdf version, readable with the Kindle app
b) the publisher-readable with the VitalSource Bookshelf app
c) a stand alone app for the textbook
d) online access to the textbook using a code when you buy the physical book (often only for 1 year)
e) your institution may have bought a digital package from the publisher
In my second year, all of my textbooks were available one way or the other digitally. Even if you don't find a quick answer from the institution, a quick trip to the publisher's website may prove fruitful.
