Pick, Bernhard. "Preface" Paralipomena: Remains of Gospels and Sayings of Christ. Chicago: Open Court Publishing Company, 1908
Pick observes that studies of non-canonical sayings attributed to Jesus have been published numerous times throughout history. This collection includes items which are considered authentic by some scholars but not by others, leaving the decision up to the reader (Pick 1908, x-xi). The book itself is divided into 14 chapters, with material presented in English without significant commentary.
