Readable
Format: Hardcover, Format: Hardcover
Not at all what I would consider “Very Good” condition, as the book was described. Pretty disappointed to be honest, considering I paid over $100 for this. It’s beaten up, torn, and dirty, but it’s readable.

Not as listed!
Format: Hardcover
I paid nearly 300 dollars for this book and it was not as listed. I bought this because it was listed as new, but the book arrived with a broken binding, highlighting and writing throughout the pages, and the course ecode was already used. Unfortunately, I cannot use it for my studies.

Coverage lined up nearly perfectly with my fed courts class
Format: Paperback
Almost every case we covered in class and definitely every concept is covered, and explained helpfully, in this E&E. The problems are helpful, too.

Great Federal Courts supplement
Format: Paperback
This E&E book really helped with Fed. Courts! Incorporate the public v. private law models/SOP and federalist v. nationalist paradigms which my professor used in the course. This version doesn't have some of the newer cases (TransUnion v. Ramirez). The standing section could have more info but standing is one of the easiest doctrines in fed courts. The Habeas Corpus, particularly the Teague Doctrine and AEDPA, section is excellent. The only big thing this book does not include are universal injunctions and the scope of remedies (outside of standing, anti-injunction act, and section 1983).
