The Hotham family's collection of printed material relating to the civil war and interregnum period is now held in the Hull History Centre. Early English Books Online has been used to identify these tracts with Thomason numbers (in bold), which have been given in preference, although Wing numbers have been cited if the tract is not listed in Thomason. The length of each tract in pages is also given. The collection is listed under 82 items but contains over 400 pamphlets and ordinances; the ordering and numbering here retains those of the archive catalogue. Items 80 to 82 were deposited in the East Riding Record Office on 7 April 1972. A great deal of the collection consists of the paper war that preceded and accompanied the outbreak of war in 1642. This was probably gathered and preserved by the Hothams, anxious to justify their defiance of the king, and to monitor their reputations in print. Items 76 to 79 are four bound volumes of acts and ordinances of the interregnum parliaments, between them containing over 250 items. These may have been collected and bound by or for Durand Hotham to inform his employment as an East Riding justice of the peace during the interregnum. A handful of post-Restoration tracts are appended at the end. For a detailed discussion of this collection, see A.L. Capern, ‘The Hotham family and its papers’, Archives, 23 (1998), pp. 102–103.
