'particular title picked' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'up among the many books' is the wordplay.
'up' is a reversal indicator (in down clue: letters go upwards).
'among' says the answer is hidden in the clue.
'emanyb' can be found hidden inside 'the many books'.
'emanyb' back-to-front is 'BYNAME'.
