Index of Middle English Prose


The Index of Middle English Prose, which began publication in 1984, aims to catalogue all items of Middle English prose surviving in manuscript form. Its founding General Editor was A. S. G. Edwards. Twenty-three volumes, covering the contents of over seventy manuscript collections, have now been published by D.S. Brewer, Cambridge.

Summary lists of the volume contents

This first version of the IMEP website contains a full list of volumes and summary lists of the prose contents of the first twenty. There is also an explanatory list of abbreviated names of all the manuscript collections.

Searchable indexes

More importantly, and courtesy of Boydell & Brewer Ltd, the website gives access to searchable indexes to the first twenty volumes, providing a valuable research tool for Middle English scholars. Four merged indexes to volumes 1-20 are now freely available for searching, as follows:

  • Incipits (the opening words of a text). Acephalous (headless) incipits will be found at the end of the list.
  • Reverse explicits (the closing words of a text, alphabetized according to the final word). Incomplete explicits will be found at the end of the list. This index is new. It was not included in the printed Index to Volumes I-XX for reasons of space and cost.
  • Titles of and rubrics to texts
  • A general index, including subjects and names

If you wish to search using the characters þ or ȝ, you can copy them from this sentence before proceeding to the indexes.

Searching any of these indexes will produce a list of results sorted alphabetically. The second and third columns (the manuscript reference and the volume number) can also be sorted by clicking on their headings. Please be aware, however, that the indexes to the individual volumes have not been compiled to a standard pattern, with resulting inconsistencies. In particular the Incipits index contains some rubrics. For a detailed explanation, see the Introduction to the printed Index of Middle English Prose: Index to Volumes I-XX, compiled by Kari Anne Rand (Cambridge: Brewer, 2014).

Advanced search with Regular Expressions

IMEP search uses what are known as regular expressions, which are especially valuable when searching for variant spellings. Click here for a more detailed guide, including further examples, but the following techniques are particularly useful. Note that if you search without using expressions, the string of characters in question will be found wherever it appears, including as part of a word.

  • To search for a string of characters at the start of an incipit, use ^, as in ^Parce
  • For a single-character wildcard, use a point, as in or (note that a point also serves as a truncation symbol at the end of a word)
  • To search for a word beginning or ending in a certain way use \y at beginning or end, e.g. \ywom or man\y
  • To isolate a word, use \y at both beginning and end, e.g. \ywoman\y or (using a wildcard) \ywom.n\y
  • To search for specific alternative spellings, put the relevant letters in square brackets, as in hea[vu]en
  • To search for alternative spellings involving more than one character, you can use round brackets and the vertical bar character (|), as in (þ|th)e
  • These various techniques can be combined, as in ser[vu](a|au)nt or ser.(a|au)nt or as in (&|\yand\y) to search for ampersands as well as the word 'and'

Browsing the indexes

The Regular Expressions search facility will to a large extent help users find specific items, but it is anticipated that they will also need to browse through the indexes. In this connection it may be helpful to be aware that the sorting order of items in the electronic indexes differs from that in the individual IMEP volumes and the printed Index to Volumes I–XX. Details can be found here.

Forthcoming volumes

Work is currently in progress on a number of new volumes. The first to appear are expected to be those for the Bodley Collection, Bodleian Library, Oxford; New York City libraries; and Trinity College, Dublin. Other volumes in progress will cover manuscripts at Harvard and Yale; in Magdalene College, Cambridge; London libraries (excluding the British Library, Lambeth Palace Library and the Wellcome Library); Glasgow University Library; Stowe and Arundel Collections, British Library; the Wellcome Library, London; South-West England; Longleat House, Warminster; St John’s College, Cambridge; French and Belgian libraries; Cotton Collection, British Library.
