Publications and public relations

Since 2006, Dr Evan Jones and his associates have been engaged in a widely-reported search to determine what Dr Ruddock found and where she found it. The published results of their work can be found below – much of which is available for free – as well as well as information on papers presented by project members.

Publications: document transcriptions

The Project has published a number of annotated document transcriptions through the University of Bristol's electronic repository (formerly ROSE, now PURE), some of which include photographs of the original documents and / or lengthy introductions. These are permanently-available sources for use by students and researchers. In addition, we are posting some documents on other sites / e-repositories, such as and the UK Data Service. This is being done to try to increase the accessibility of the files. Where additional copies are available, this has been indicated.

Publications: Bristol 'particular' customs account transcriptions

The Bristol 'particular' customs accounts record the duties levied on merchandise imported or exported from the Port of Bristol. They form an essential source for understanding Bristol's trade and shipping in the the fifteenth-seventeenth centuries. Sixteenth-century customs accounts, covering eleven individual years, have previously been published electronically and in hard copy as part of the ESRC-funded project: Ireland-Bristol Trade in the Sixteenth Century. The value of this material for understanding the Bristol discovery voyages had been established by Evan Jones, in his 2006 'Matthew of Bristol' article. One element of the Cabot Project's work has thus involved the identification, transcription and analysis of the surviving Bristol 'particular' accounts of the mid-late fifteenth century. Drafts of transcriptions were also employed extensively by those presenting papers at The World of the Newport Ship conference (2014) and, subsequently, in the volume dedicated to this subject.

For technical reasons, the introduction to each account, and the EXCEL database for each, have been published as separate files. Ranging from 500 to 7,000 words, each introduction provides an extended commentary on the account including, where relevant, the arguments for its identification and dating. Editorial conventions are set out in the introduction to the 1461 account. They are not repeated at length in other files.

We intend in time to publish all the extant customs accounts, first as electronic trancriptions in EXCEL and then in hard copy through the Bristol Record Society. The electronic versions are being published primarily through University of Bristol e-repositories. However, as indicated below, additional copies have been posted on

Publications: web articles

Dr Jones has posted a number of short web-articles, one MA dissertation and some out-of-print publications that relate to the Bristol voyages of this period. While these are intended to be of use to students / researchers, the permanence of these items is not guaranteed and the articles themselves may be revised over time.

Public engagement

Having been aware, from the start, of the strong public interest in the Cabot voyages, we have sought to communicate our research findings to the general public. This has included lectures to local societies and the creation of a Schools Group  to introduce our research to Bristol school children. Our decision to produce a short book, aimed at a general audience, was a major part of this process.

Over the years, there has been extensive media coverage of the project's findings. Some of the highlights are listed below:
