The bulk of the collection concerns the last three decades of the Regiment's existence and the emigration. Cataloged items consist of 3 photographs of Tsar Nicholas II and a receipt signed by one Captain Lanta, dated 1720. The correspondence is almost all after 1917. The manuscripts include a history of the Regiment from its formation and some other historical pieces by Viktor I. Meshchaninov. Most of the other manuscripts -- chiefly officers' memoirs -- concern the period of WWI, the Revolution, and the Civil War. Of other materials relating to the Imperial epoch, mention may be made of the lists of members of the Regiment since its formation compiled by some regimental historian; biographical sketches of many officers; field orders, topographical maps, certificates awarding medals, etc. The Association of former officers generated much material: accounts, minutes, souvenirs of commemorative dinners, etc. A rich store of photographs forms part of the collection. These include both individual and group portraits of members of the Regiment and of the Imperial family. Especially fine photos of the last 2 tsars, their families, and various urban landscapes are found in the album "Photographies du comte Nostitz.".

Correspondence, manuscripts, documents, photographs, memorabilia and printed materials of John Mitchel, John Purroy Mitchel, and other members of the Mitchel and Purroy families.
