“Yet will I leave a remnant, that ye may have some that shall escape the sword among the nations, when ye shall be scattered through the countries”
— Ezekiel 6:8

Waterloo, University of Waterloo, DRAGEN Lab, Vellum Leaf from a Book of Hours, Recto.
By request, in collaboration with the University of Waterloo, the RGME prepares a special 2025 Autumn Colloquium on the phenomena of widely dispersed remnants of dismembered manuscripts and other written materials scattered at the hands of biblioclasts such as Otto F. Ege (1888–1951), for a variety of purposes more and less laudable. We will showcase work being done in various centers and by many individuals on these materials, as part of long-term, laborious, significant, and sometimes dispersed research to identify, reclaim, and, insofar as possible, virtually reconstruct the originals and place them in context.
We seek to gather perspectives on the challenges and opportunities presented by the dispersed manuscript or other materials which survive, albeit disordered or reordered, after passing through the hands of collectors-turned-biblioclasts, for whatever reasons.
A main focus, given the number and variety of projects dedicated to them, will be the manuscripts and other materials dispersed by Otto F. Ege and his collaborators, notably his wife/widow Louise and the New York book-dealer and book-breaker Philip C. Duschnes (1897–1970). Yet, not least because many of their remnants have joined or become intermixed with fragments dispersed by others and through diverse processes in varied collections, it is worthwhile to consider that complex factor for their effective study as well.
We seek to showcase the work of these projects, compare notes about issues and methods of research, and set the legacy of those biblioclasts in the context of others working as predecessors, contemporaries, or followers, as they also redirected the course of manuscript and related studies by disrupting and dislocating its evidence.
The ‘delivery methods’ of dispersal range from assemblages of sets of fragments as specimens in Portfolios, Leaf-Books, Albums, Scrapbooks, or Loose Leaves which might circulate in mats with or without labels, on their own, or in groups sans identifying information. In effect, many of these remnants were cast out on their own as no-name ‘orphans’ whom expertise, serendipity, and circumstance might recognize as ‘foundlings’ or find forever homes, whether virtual or actual. (See The “Foundling Hospital” for Manuscript Fragments.)
Our Colloquium highlights the processes of recovery by multiple, interlinked, and interlocking means, as we gather representatives from the fields of manuscript studies and fragmentology to share their stories, processes, progress, and accomplishments.

Scope
The University of Waterloo and the RGME propose to co-host an international Colloquium with hybrid functionality, for access by a wide audience with interests in multiple subjects. Our two educational organizations in Canada and the United States respectively combine experience and skills to produce a scholarly event with companion publications pre- and post-event, to promote and disseminate research work and discoveries in multiple, interrelated fields of study.

Our plan takes its starting point from the wish to gather expertise and perspectives from a different collections of manuscript materials — such as at the Medieval DRAGEN Lab (Digital Research Arts for Graphical & Environmental Networks — and the rich variety of new and long-term projects (both institutional and individual) dedicated to research on the medieval Western manuscripts despoiled and dispersed by Otto F. Ege and his collaborators.
These initiatives include the new project by the Cantus database (Cantus: A Database for Latin Ecclesiastical Chant – Inventories of Chant Sources) to produce a database of the musical manuscript fragments in Ege’s Portfolio of Fifty Original Leaves from Western Manuscripts (FOL). This notorious Portfolio was issued in multiple sets now widely dispersed in public or private collections through North America and beyond. Like others of Ege’s Portfolios, some sets are lost, or lost track of; some have themselves become fragmented, as parts have been removed, as specific manuscript specimens were further disjointed from their relatives, original or newer companions in the biblioclasts’ assemblages. Some of these ‘orphans’ or cast-offs have lost their identifying Ege mats or labels, further to complicate the issues of identification, recognition, and retrieval.
The RGME’s long-term project of research in these fields focuses on the variety of Ege’s Portfolios overall. Dedicated to specific genres of books, such as Famous Books or Famous Bibles, they include not only manuscript fragments but also a multitude of printed materials ranging from incunabula (up to the year 1500) to the twentieth century; all were selected and arranged by Ege and his circle as specimens of the graphic arts and book arts for instruction and display. (For examples, see our blog on Manuscript Studies and its Contents List for Ege materials.)

Research on the surviving evidence on many fronts and in multiple centers can bring expertise to bear upon specific genres (such as manuscripts containing music). So, too, it reveals the processes of workshop practices over decades in the destruction, re-constitution, and further distribution of the original books. For example, such elements have bearing upon the provenance of individual fragments and potential impact upon that of other fragments whose provenance might not otherwise be known.

Given the progress of these and other projects in various centers concerned with Ege’s legacy, the time is right to bring their representatives (established scholars, curators, collectors, and others, as well as younger scholars) together to compare notes, showcase their work, and strengthen contacts between individuals and centers across borders.
By examining the book-breaking practices overall by “Ege & Co.” in the wider context of biblioclasts over time, including many of Ege’s contemporaries, predecessors, and followers, we might gain fuller knowledge of the individually as well as collectively destructive habits and their legacy. Likewise by comparing notes, surveying the results so far of different projects, and, it might be, identifying more of the seemingly lost fragments in unknown or unexpected places, our Colloquium could cross thresholds and open more gateways to wider knowledge.
Such larger contexts provide wider horizons and more comprehensive awareness of the destructive tendencies towards books in given times and places. They can demonstrate, by examination and comparison, the particular characteristics or ‘style’ of the collector, book-breaker, book-seller, and the resulting forms as altered pieces or bodies of evidence for the lost and damaged originals. Among notable predecessors for the genre can be counted the albums of “visually appealing” manuscript fragments created by Samuel Pepys (1633–1703) or the cuttings prepared by John Ruskin (1819-1900) and others.
Examining the complex legacy of these various re-creators of medieval manuscripts and other written materials and the range of projects dedicated to them from perspectives and fields of many kinds, sometimes integrated across a broad spectrum encompassing expertise in the arts and sciences, can advance knowledge in individual projects as well as in wider discourse relating to the transmission of written evidence from generation to generation and century to century, with losses, discoveries, and reconstitutions along the way.
Our focus for the co-sponsored Autumn Colloquium is the legacy of book-breakers, book-destroyers, and book-recreators active in multiple centers in Europe, the British Isles, and North America (at least), with the fragments produced by their activities and transmitted to diverse locations worldwide, often without appropriate identifying information. Our task, as receivers of the evidence from such disruptions, is to make sense of the evidence, identify it appropriately, recognize its characteristics as bodies of witnesses with a complex history, compare information about diverse projects (in many centers) relating to these materials, gather feedback, and disseminate the results to a wide audience.

Purpose
This 2025 Colloquium stands within the long tradition of symposia, colloquia, workshops, and other scholarly events of the Research Group on Manuscript Evidence, now entering its second quarter-of-a-century as a nonprofit educational corporation based in Princeton, New Jersey. The RGME is dedicated to the study of manuscripts and other written records across the centuries. This year our theme is “Thresholds and Communities”.

For the 2025 Autumn Colloquium on 21–23 November, the RGME collaborates with the University of Waterloo and its range of programs and projects, including the Cantus Database and the DRAGEN Lab.
The Advisory Committee for the Colloquium comprises:
- Mildred Budny, Director, Research Group on Manuscript Evidence
- Debra Lacoste, Cantus Database, University of Waterloo; The Institute of Mediaeval Music; Digital Analysis of Chant Transmission, Dalhousie University
- David Porreca, Associate Professor; President, Faculty Association of the University of Waterloo; Co-Director, Medieval Studies Undergraduate Program; Department of Classical Studies and Department of History, University of Waterloo
Spanning three days with half-days on Friday and Sunday, the Colloquium will include a series of sessions with presentations and Q&A, roundtable discussions/panels, hands-on workshops, and exhibitions of several kinds.
To augment the scholarly sessions of presentations and discussions, we plan for displays of original materials in manuscript or other forms and demonstrations of the sounds of music represented in medieval manuscript fragments. Among them is a SoundWalk which allows passersby to access audio recordings of specific musical passages preserved on medieval leaves in collections including the DRAGEN Lab and the Cantus Database.
A Reception ending each day’s sessions will lead from the scholarly program to further conversations.

Some Results
RGME tradition produces illustrated Program Booklets for major events such as this Colloquium, with participants’ abstracts and selected accompanying illustrations, to grant insider glimpses for our audience (at the event and after) not necessarily familiar with the wide range of subjects and materials under discussion.

We explore sources of funding and sponsorship for the event as a whole. Information about the results would emerge as these explorations advance. Our aim is to have an in-person event with online access (for speakers and audience) for a fully hybrid colloquium; the online functionality would occur by Zoom Meetings (rather than Webinars with closed access). If funding proves elusive for the in-person facets as well, the event will take place online by Zoom.
We hope to welcome you to the Colloquium.
