I have few questions.
What is the difference between documents like Circular Document, Corrigendum  Document, Disclaimer  Document, Advertisement Notice Document, Appeal Document, Applaud Document, Order Document, Notice Document, Invitations of no objections advertisement Document, Annexure Document, advertisement Document, press release Document, Motion/Writ petition Document?

Can you identify one book at this point that has explained these documents in English language in questions and answer format?

What is your answer?
