In addition to Primum quaeritur, many manuscripts contain brief notes to each of the epistles indicating where they were written, with notes about where the recipients dwelt.
Selain Primum quaeritur, banyak manuskrip memuat catatan-catatan singkat untuk tiap surat yang berisi keterangan mengenai dimana surat itu ditulis, serta di mana penerima surat tersebut tinggal.
