Poorly written
Format: Paperback
I had to get this for my class. I wish I had a different textbook because it is poorly written, does not explain details, hard to follow the sentences in a certain sections, A LOT of typos (totally misspelled name of the disease). I don't think this is very good textbook material.

Informational book
Format: Paperback
Received the book in a timely manner before my semester started. The nursing policy book is required in my master/ doctorate program. The book is thorough and sheds light on policy making in a nursing perspective. A good reference book to have after the semester when you start looking into policy making.
