You might be out of luck here. I checked all the sites I know of and could find no Cliff's notes, or Spark's notes on this book. I could find no breakdowns or recordings. All I could find were book reviews and descriptions. However, someone who was clever, could read all the reviews and descriptions and piece together a pretty good book report and or term paper. Now, I would
never recommend that anyone do this of course, but I am just saying that.... it could be done easily. Simple go to one site, read a description, then go to another site and read reviews from people who have already read the book. Then combine their info with what you yourself have already read, and maybe skim the rest of the book for more details.
Amazon.com: Salem Possessed: The Social Origins of Witchcraft: Paul Boyer, Stephen Nissenbaum: Books Review of Salem Possessed
Or you could just read the damn thing. I think its only 250 pages or so. Good luck.
