Listing publications on a CV?

[Ceffyl Aedui]

Greetings.

A friend of mine is also a technical writer. She is creating a curriculum vitae 
from her existing resume. She has been asked to include publications.

In our line of work, we can have quite a few books we've written. Do you list 
publications you were hired to write under publications in a CV? Most of the 
time (at least in my experience) no byline is given in manuals, so can you even 
prove you wrote it?

How would you handle the situation if asked to prove the you had actually 
written x number of books?

Seemed like an interesting question. I didn't have a good suggestion for her, 
and thought I would ask my fellow techwrl-ers.
