What Correspondence Can Prove
Letters can establish who communicated, when, and sometimes what project or claim was being discussed. They do not prove a technical result unless the document itself gives enough detail or can be paired with patents, lab notes, or contemporary reports. This page keeps collection-level access facts separate from document-level interpretation.
