Angry testimonials? They may be at bottom of page

I believe the answer is:

crossreferences

I'm a little stuck... Click here to teach me more about this clue!

'they may be at bottom of page' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'angry testimonials?' is the wordplay.
'angry' becomes 'cross' (cross can mean annoyed or angry).
'testimonials?' becomes 'references' (reference is a kind of testimonial).
'cross'+'references'='CROSSREFERENCES'

Can you help me to learn more?

I've seen this clue in The Daily Mail.
