Official records continued — A to M possibly (13)

I believe the answer is:

documentation

I'm a little stuck... Click here to teach me more about this clue!

'official records continued a to m possibly' is the definition.
I can't tell whether this definition defines the answer.

'continued a to m possibly' is the wordplay.
'possibly' is an anagram indicator.
'continued'+'a'+'to'+'m'='continuedatom'
'continuedatom' is an anagram of 'DOCUMENTATION'.

Can you help me to learn more?

(Other definitions for documentation that I've seen before include "Written papers" , "paperwork" .)

I've seen this clue in The Times.
