Here is a collection of my favourite books on Scrum.
I find if ever I am unsure of what to do I can refer back and find an answer in at least one of these titles.
There are of course many other excellent books out there!
Agile Project Management with Scrum by Ken Schwaber
Scrum: A revolutionary approach … by Jeff Sutherland
User Stories Applied: For Agile Software Development by Mike Cohn
Agile Estimating and Planning by Mike Cohn
Agile Product Management with Scrum by Roman Pichler





I think the question on team size has its answer be revised. As per Scrum Guide and its open test, a team should not be less than 3 and more than 9. Thanks!
No, the question is good. Team size is not mandated by Scrum. Have a read of this:
