Special study in two facing pages (6)
I believe the answer is:
spread
'facing pages' is the definition.
(synonyms)
'special study' is the wordplay.
'special' becomes 'sp'.
'study' becomes 'read' (synonyms).
'sp'+'read'='SPREAD'
'in two' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for spread that I've seen before include "Parsed (anag.)" , "Open, fan out, unfold" , "Special display" , "See 4" , "Large elaborate meal" .)
