Work with actors or company behind popular type employed in Phone Booth (9)
I believe the answer is:
directory
'work' is the definition.
(directory is a kind of work)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for directory that I've seen before include "See 7" , "No longer 192 in Britain" , "Book listing phone numbers" , "Telephone information service" , "Reference book" .)
