Where can I find landmark cases in the arear of contract law?
The best place for a layperson to read the “landmark” cases in the law of contracts would be a law school casebook. It is a collection of cases, supplemented by other materials, such as statutes and the occasional scholarly article. Go to any law school bookstore. Look for used contract texts. For your purposes–getting a generalized feel for the subject–any of the casebooks will do fine. Note: do not bog yourself down with a hornbook. Hornbooks are different, they are more daunting to read and they do not generally discuss cases. Though the “super landmark” cases, such as Hadley v. Baxendale or the Kent Building Products or Victoria Laundry cases will be discussed. But less than 10% of the content of a hornbook will revolve around landmark cases, while in casebooks, around 35% of the content delves into such leading cases.
