Writer reflected in someone's bibliography (5)
I believe the answer is:
ibsen
'writer' is the definition.
(dramatist Henrik Ibsen)
'reflected in someone's bibliography' is the wordplay.
'reflected' is a reversal indicator.
'in' indicates a hidden word.
'nesbi' is hidden in the letters of 'someones bibliography'.
'nesbi' written backwards gives 'IBSEN'.
(Other definitions for ibsen that I've seen before include "Norwegian dramatist, d. 1906" , ""Doll's House" dramatist" , "Is Ben a playwright?" , "foreign author" , "not one for 'All work and no play ...'" .)
