The Hayle Mill Archives are regarded as unique in British papermaking history in terms of their scope and completeness. This is unusual as most companies disposed of their records by intent or accident and very few paper companies survive that existed in anything like their present form prior to 1900. The Hayle Mill collection dates from the 1830s to 2011 and is particularly complete from 1850.
