Scraps of paper I’m obliged to include in sort of map (5)

I believe the answer is:

iotas

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

'scraps' is the definition.
(I have seen 'Tiny scraps' mean 'iotas' so perhaps 'scraps' could also mean 'iotas')

'of paper i'm obliged to include in sort of map' is the wordplay.
I cannot really understand how this works, but
'of' could be 'o' and 'o' is located in the answer.
'paper' could be 'i' (the i is a UK newspaper) and 'i' is found in the answer.
The remaining letters 'tas' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for iotas that I've seen before include "Tiny amounts" , "Jots, very small amounts" , "Tiny scraps" .)
