Following One Story Across Several Repositories
Launch library · evergreen read

Rarely does a single archive hold everything relevant to a story worth telling, particularly for subjects whose lives crossed institutional boundaries. Personal papers might sit in one institution, official records in another, and photographic material in a third entirely, each with its own catalogue system and its own separate rules for access.
Tracking a subject across repositories means keeping a master log of what you have already checked and where, since the same name can appear differently indexed in each separate system a researcher encounters. Consistency in your own notes becomes the thread that ties the scattered evidence together into one coherent picture.
The payoff is a fuller picture than any single collection could ever offer on its own. A gap in one archive is often filled, quite unexpectedly, by a stray reference sitting in another institution's holdings entirely. That kind of discovery is one of the quiet rewards of archival research, and it rarely happens to a writer who only ever checks a single repository.
