These papers were originally accumulated by the office of William Dickson, overseer of the Alnwick Corn Exchange from its opening in 1862 until 1880. Dickson, a solicitor in Alnwick and local benefactor, in fact raised the money for the building of the Alnwick Corn Exchange, and then oversaw the building of the Exchange, before then taking responsibility for its running for the next twenty years. These papers are particularly fascinating as the Exchange was used not only as a market but also as a venue for entertainment, and both the accounts and correspondence files contain much information about the acts which were booked druing this period.

The archive contains, in roughly chronological order, correspondence and legal agreements relating to the purchase of the site and the subsequent building programme; correspondence about similar markets in Berwick and Kelso, a Broadside announcing the opening and detailing the functions of the new Exchange, accounts for the period 1862 - 1880, correspondence for the period 1862 - 1880; details of the Exchange's sale in 1880.
