Dull, short book, one of a collection (4)
I believe the answer is:
matt
'book one of a collection' is the definition.
'matt' can be an answer for 'book' (I've seen this before). I am unsure of the 'one of a collection' bit.
'dull short' is the wordplay.
'dull' becomes 'matte' (similar in meaning).
'short' means to remove the last letter.
'matte' with its final letter removed is 'MATT'.
Can you help me to learn more?
(Other definitions for matt that I've seen before include "Lacking a shine" , "Telegraph cartoonist" , "Dull uniform finish" , "Dull, lustreless" , "(Of surface) dull" .)
