Name of prize book appearing in the Christmas period (5)
I believe the answer is:
nobel
'name of prize' is the definition.
'Nobel' can be an answer for 'prize' (as in the Nobel Prizes). I'm not sure about the 'name of' bit.
'book appearing in the christmas period' is the wordplay.
'book' becomes 'b' (abbreviation for book).
'appearing in' indicates putting letters inside.
'the christmas period' becomes 'noel' (Noel means Christmas).
'b' placed inside 'noel' is 'NOBEL'.
Can you help me to learn more?
(Other definitions for nobel that I've seen before include "he provided prizes" , "Source of prizes" , "Giver of many prizes" , "Prize giver" , "Prize title" .)
