Though the book is almost 5 years old, not only is it a realistic approach to makerspaces, it gives the stats to back up what works and what doesn't, what each of 150 (I think) different libraries (public, academic, and school) have found successful or haven't used.
It offers tons of websites and blogs for unique ideas.
It describes the budgeting, space, staffing, time commitment to each, different kinds of makerspaces, how and where to find the supplies, funds, marketing and more...really is a practical guide.
I've read a lot of librarian's guide books and I found myself taking notes on this one...as in...a lot of notes.
