What a Catalogue Record Leaves Unsaid
Launch library · evergreen read

A catalogue entry is a summary, not a transcript, and summaries compress by their very nature. A single line describing a folder of correspondence cannot capture every name, date or aside contained within it, so treating the entry as complete is a quiet trap for the unwary researcher working to a deadline.
Cataloguers work under real time pressure and shifting descriptive standards across decades, which means older entries are often noticeably thinner than newer ones covering similar material. A brief description does not mean a thin file, and a detailed one does not guarantee everything relevant has actually been captured within it.
The only reliable move is to open the folder anyway whenever the subject genuinely matters to your project. Catalogue records are excellent for narrowing a search and poor as a substitute for reading the actual document sitting in front of you. This extra step rarely takes more than a few minutes, and it is exactly the kind of minutes that separate solid research from research that only looks solid.
