'part of book' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'cuts out in coastal town' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'in' is an insertion indicator.
'coastal town' becomes 'dover' (I've seen this in other clues. I am not sure about the 'coastal' bit.).
'cuts' is an anagram of 'ustc'.
'ustc' placed inside 'dover' is 'DUSTCOVER'.
