The following posts and essays describe our methods and workflows for working with the London bills of mortality.

How Can You Map with Bills of Mortality Data?

By Cecilia Ward

Recently, I had the pleasure of presenting original research and maps about early modern death at the 2024 American Historical Association in San Francisco. I showcased maps between 1656 and 1680 based on general bill data. That span of years offered interesting data to showcase, including the major …

What happens when 'Is Missing' becomes more literal?

By Emily Meyers , Cecilia Ward

As Death by Numbers has evolved and developed, there have been some slight changes to our workflow, which caused us to reconsider how to work through and present our data. One of those shifts came about because we set up our workflows using early 18th century bills as a model, before shifting to …

Building a Data API for Historical Research

By Jason Heppler

We are in the process of building out a data API to support the data work we’re undertaking with the transcription of the plague bills. We anticipate hundreds of thousands of rows of data by the end of our transcription process, and we wanted an easy and efficient way to work with that data. …

Visualizing the Bills of Mortality

By Jason Heppler

One of the ways we are using the transcribed bills of mortality is in data visualization and mapping, in an effort to ask new questions and revisit old ones. At the Southern History Association’s annual meeting in Baltimore, we presented preliminary work on data visualization and the data API. An …

How We Get Things Done: The Transcription Workflow

By Megan Brett , Dan Howlett

Figure 1. Bills of Mortality Workflow. Once items are added to DataScribe and the datasets are ready for transcription, the transcription workflow begins. The project owner can assign users one of two roles: reviewer or transcriber. Reviewers can edit all records and items, regardless of the item’s …

From Archival Sources to Computational Analysis, Part Two

By Megan Brett , Megan Mitchell

In our last post, we explained how we used Tropy to organize photographs of bound bills into items, concluding with the export of the item metadata using the Tropy CSV Export plugin. This post covers the other part of the process of going from digital images to items in a datascribe item set. If you …

From Archival Sources to Computational Analysis, Part One

By Megan Brett , Megan Mitchell

Have you ever wondered how a complex project like Death by Numbers comes together? This post is the first in a series about the workflow that takes us from archival sources to transcriptions formatted for computational analysis. Let’s begin with digitization. Figure 1. diagram of image preparation …
