Series I holds letters sent between Wouk and his colleagues at Columbia University, admiring fans, personal friends, publishing houses and journals, and family members. The bulk of the correspondence consists of complimentary letters sent to Wouk in regards to his book Marjorie Morningstar, although there are also some references to The Caine Mutiny. Condolence letters for the death of his son, personal correspondence, and letters from Jewish institutions are found here. This series is arranged alphabetically by the individual's last name or the name of the institution. Note that there are considerable gaps in this series: the letters are primarily from the 1940s through the late 1950s with some dating from the late 1990s.
