The Index of Middle English Prose project was launched at a conference in Cambridge in 1978 on the initiative of A. S. G. Edwards and Derek Brewer. At its inception, the aim of those involved was a publication analogous to Carleton Brown and Rossell H. Robbins's Index of Middle English Verse. But when Brown and Robbins published their seminal volume, more than three decades of manuscript study and indexing lay behind it; the editors, whatever the limitations of their product, had a hands-on knowledge of the materials they presented. At the time when a comparable index to present Middle English prose was conceived, such work had scarcely begun in this area.

Hence, as a first step, a number of scholars, working independently, undertook to identify relevant materials on a collection-by-collection basis. The results of these investigations, a listing of all Middle English prose items uncovered after careful searching, were to be presented in a sequence of stand-alone volumes or ‘handlists’ published by Boydell & Brewer. The first appeared in 1984, and the present volume is the twenty-fourth in the series. The main body of text in each volume identifies and contextualises, manuscript by manuscript, the Middle English prose material found in a given collection or collections. At the back of each volume are indexes derived from these descriptions. Those indexes will form the basis of the final, combined Index of Middle English Prose.

The IMEP is concerned with material composed between c. 1200 and c. 1500. For the terminus a quo this means as a general rule that if a manuscript is not included in N. R. Ker's Catalogue of MSS Containing Anglo-Saxon, it is considered to be Middle English. In addition, we aim to include all later transcrip¬tions of ME texts produced before 1600.

There have been adjustments in detail over the years, but the handlists now follow an established format. Each volume contains an introduction with a general account of the history, development, and scale of the particular collection or collec¬tions described. This is followed by a summary list of the Middle English prose contents of the volume.

The relevant materials discovered in the manuscripts are presented in the order of the shelfmarks of the collection(s) described. Each entry begins with references to published descriptions of the manuscript in question.

The Middle English prose items in the manuscript are then numbered and presented in sequential order. Readers should note that this sequence also includes relevant material written by users in the margins, or on binding leaves.
