Possibly used to produce book: Running With The Crowd (introduction missing) (8,5)

'possibly used to produce book' is the definition.
(a printing press might produce a book)

'running with the crowd introduction missing' is the wordplay.
I cannot really see how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
'crowd' could be 'press' (to press can mean to crowd around) and 'press' is located in the answer.
This explanation may well be incorrect...
