Identify the document
Begin with the author, date and intended audience. A petition, press release and newspaper report have different purposes. State which kind you are reading before summarising its message.
Keep quotations attributed
An advocacy document expresses a position. Attribute the position to its author and check factual assertions against other records. A link from a later essay can establish that a document was cited, without proving that all its claims were accurate.
Avoid inventing continuity
A past campaign does not establish a current organisation, membership list or petition. Where the exact original document has not been recovered, this collection leaves it unavailable rather than recreating statements or signatures.
