This is why librarians and your instructors are constantly asking you to take advantage of your academic privilege by using the library databases. My hope is that someday more academic information will be freely available. Until then - we should all be part of this fight.
I am glad that librarians and instructors are using these freely available materials more often than having you buy a textbook. I truly hope that there are more freely available materials available to future generations, especially with the way the economy is right now.
