To decide whether members with the same name are the same person, the Shakespeare and Company Project developed a set of guidelines based on activity date and type. Consider the case of “Miss Wilson.” The name appears in the logbooks five times, associated with membership activity on November 9, 1923; April 10, 1926; August 20, 1927; September 7, 1927; and September 14, 1927. We infer that two of these activities belong to the same Miss Wilson: on August 20, 1927, she joined the lending library for one month, paying a 100 francs deposit, and on September 14, 1927, she received a 100 francs reimbursement. Do the other activities belong to this Miss Wilson? We do not know. We suspect that the activity on September 7, 1927—a reimbursement for 50 francs—belongs to a different Miss Wilson. When we are not confident that two activities belong to the same person, we keep them separate. As a result, some names appear multiple times on the list of lending library members.
