Good books are put up online verbatim (7)
I believe the answer is:
literal
'verbatim' is the definition.
(synonyms)
'good books are put up online' is the wordplay.
'good books' becomes 'lit' (abbreviation for literature).
'are put up' shows that the letters should be reversed in order.
'online' becomes 'lare' (I can't justify this - if you can you should give a lot more credence to this answer).
'lare' in reverse letter order is 'eral'.
'lit'+'eral'='LITERAL'
(Other definitions for literal that I've seen before include "Ill rate (anag.)" , "Lacking imagination; misprint" , "Simple" , "character fault?" , "without distortion" .)
