Most folders within the Max Jacob papers contain multiple letters. The letters are organized chronologically based on the dates given in the index. The index is undated and is provided at the beginning of the box; it lists each letter in the collection, the letter's date, and the number (roman numeral) the letter was assigned. The dates used to organize the collection are the dates provided in the index, not necessarily the dates written on each letter. Almost every letter was written by Max Jacob to Marcel Jouhandeau. Unfortunately, the other half of the correspondence (Marcel Jouhandeau to Max Jacob) is not in the collection. There is one letter that was written to Max Jacob instead of by him; this letter was written by André Jullien du Breuil and was later sent on to Marcel Jouhandeau with additions from Max Jacob. There are also a few letters written by Jacob to Elisabeth Toulemon and one letter written to Madame Paul Jouhandeau, who was Marcel's mother. All of the letters are written in French, and their dates range from 1923 to 1940. However, the bulk of the correspondence is from before 1930. Most of the letters are written on paper, but a few are on postcards. Shelved with the collection is an extraneous envelope regarding the acquistion of the letters.
