Yours truly on way to work organised attorney's notes (9)
I believe the answer is:
memoranda
'notes' is the definition.
(memorandum is a kind of note)
'yours truly on way to work organised attorney's' is the wordplay.
'yours truly' becomes 'me' (the person that set this crossword).
'on' says to put letters next to each other.
'way to work' becomes 'mo' (I've seen this in other clues).
'organised' becomes 'ran' (I've seen this before).
'attorney' becomes 'D.A.' (abbreviation for District Attorney).
'me'+'mo'+'ran'+'da'='MEMORANDA'
(Other definitions for memoranda that I've seen before include "Written messages or notes" , "Communications" , "official minutes" , "Records" , "Notes recorded for future use" .)
