Books accompanied by the relevant questionnaires

[Yuppie]

Is this statement perfect for inclusion in a formal lettet or does it need to be cleaned out?

Books accompanied by the relevant questionnaires should be submitted to the research unit by no later than 18 June 2009.

Regards.

Hi...Yuppie...
this statement looks like an announcement....
and I don't see how you are going to insert it in a formal letter...
but in either way...it seems perfect in grammatical stance..
