Interesting problem, John.
I have probably even less experience with json than you do, so I'm
taking this as an opportunity to learn with you.
Suggestions:
1. Try your example with Python 2 rather than Python 3.
Bill,
Thanks for the reply. I wasn't sure how to get Python 2 through the cmd
or IPython, so I went through ArcGIS, but it's mostly the same result:
>>> file = open('books.json','r')
>>> text = file.read()
>>> text = json.loads(text)
Runtime error
Traceback (most recent call last):
File "<string>", line 1, in <module>
NameError: name 'json' is not defined
>>> import json #whoops, forget to do that first in this go 'round.
>>> text = json.loads(text)
Runtime error

2. Take your file and make it into a string literal in your program,
and try calling json.loads with that as an argument.
I am not sure I follow what you meant, but this was what I did:
In [26]: file2 = open('books.txt')
In [27]: text2 = file2.read()
In [28]: text2 = json.loads(text2)
