British History Online

• 1. Introduction

  ›

  British History Online is a digital library holding primary and secondary sources on the medieval and modern history of Great Britain and Ireland. It began as a one-year pilot project in 2002, and what started as a modest experiment has grown into a resource spanning England, Scotland, Wales, and Ireland. Two institutions share stewardship of the whole enterprise: the Institute of Historical Research at the University of London, and the History of Parliament Trust. Their partnership is what keeps the library running as a cooperative venture rather than a purely commercial one. Most of what British History Online holds is freely accessible, though a portion of the collection sits behind a subscription. The questions the library raises are worth sitting with: what does it mean to bring centuries of official records, local surveys, and parliamentary journals into a single searchable place, and which corners of British history does it illuminate that might otherwise stay dark?

• 2. Sources and Holdings

  ›

  The Calendar of Close Rolls, the Letters and Papers of the Reign of Henry VIII, and the Journals of the House of Lords and House of Commons are among the major primary sources held by British History Online. These are not light reading. They are the working documents of royal administration and parliamentary debate, often running across many volumes and years. Alongside them sit secondary works: the publications of the History of Parliament, the Victoria County History, the Royal Commission on the Historical Monuments of England, and the Survey of London. Together they mix the raw material of history with the scholarly apparatus built to interpret it. The Victoria County History in particular is a long-running project that has mapped English counties in exhaustive detail, making its presence on the platform especially useful for local and regional research.

• 3. Geography of Coverage

  ›

  The platform organizes its content by region, covering every part of England as well as Ireland, Scotland, and Wales. England is divided into five broad areas: the East, the Midlands, the North, the South East, and the South West, each mapped against historic county boundaries rather than modern administrative ones. Bedfordshire, Cambridgeshire, and Suffolk fall into the East; Cornwall, Devon, and Dorset into the South West; Durham, Lancashire, and Yorkshire into the North. London receives its own category, drawing on the historic county of Middlesex as well as portions of Surrey, Essex, and Kent that now fall within the 32 London boroughs. Counties in both Surrey and Kent appear under both London and the South East, reflecting the way historic boundaries and modern geography overlap and sometimes collide. Ireland, Scotland, and Wales each appear with their own historic county structures intact.

• 4. Version History and Growth

  ›

  Version 5.0 of British History Online launched in December 2014, more than a decade after the platform first appeared. That release carried a set of new features designed to make the collection more navigable: subject guides aimed at researchers working in local history, parliamentary history, and urban history. Version 5.0 also introduced a dedicated viewer for the site's collection of historical maps and Epoch 1 Ordnance Survey maps, bringing a visual layer to what had been a predominantly text-based resource. The jump from the 2002 pilot to Version 5.0 represents a span of twelve years of incremental development, each version expanding what the cooperative between the Institute of Historical Research and the History of Parliament Trust could offer to researchers and the wider public.
