Andersen revealed in his autobiography that while writing his "Princeton Union-Eagle" editorials, he wrote a column on book collecting using the name, Arne Kjelsberg, his father's first two names. He did not reveal his authorship of the column for many years, though a close friend correctly guessed. Long a member of the bibliophilic Ampersand Club, Andersen's Arne Kjelsberg articles were published the year following his death in honor of the Ampersand Club's 75th anniversary, in 2005. Compilation of the volume commenced while Andersen lived, and he expressed hope to attend its publication party.
