'authors did?' is the definition.
I can't judge whether this definition defines the answer.

'work on them regularly' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'work'+'on'+'them'='workonthem'
The alternate letters of 'workonthem' are 'WROTE'.

'as' acts as a link.

Can you help me to learn more?

(Other definitions for wrote that I've seen before include "Inscribed" , "Composed (music)" , "Put to paper" , "Penned" .)

I've seen this clue in The Times.
