Gaps author created for inscriptions (10)

I believe the answer is:

autographs

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

'inscriptions' is the definition.
The definition and answer can be both related to communication as well as being plural nouns.
Perhaps you can see a link between them that I can't see?

'gaps author created' is the wordplay.
'created' indicates an anagram (I've seen 'create' mean this).
'gaps'+'author'='gapsauthor'
'gapsauthor' anagrammed gives 'AUTOGRAPHS'.

'for' is the link.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
