Simple job to enquire after Yeats edition (4,4)

'simple job' is the definition.
(I know that easy task is a type of simple job)

'enquire after yeats edition' is the wordplay.
I cannot really see how this works, but
'enquire' could be 'ask' (to enquire is to ask or question) and 'ask' is found within the answer.
an anagram of 'yeats' is 'easyt' which is within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

'to' is the link.

Can you help me to learn more?
