Digital archives are never complete, and that selection bias can quietly distort empirical studies built on them. This paper introduces an agent-based model that simulates both the sending of historical letters and their subsequent loss to archiving, allowing counterfactual correspondence networks …

New preprint: …

Distinguishing gradual change from the emergence of genuinely new directions is a central challenge in tracking how research fields evolve.
