2020 Reprint of 1926 Editions. Full facsimile of the original editions and not reproduced with Optical Recognition software. This edition includes two titles published into one bound volume. Rutherford Hayes Platt, in the preface to his 1963 reprint of this work, states: "First issued in 1926, this is the most popular collection of apocryphal and pseudepigraphal literature ever published."

The translations were first published, under this title, by an unknown editor in The Lost Books of the Bible Cleveland 1926, but the translations had previously been published many times. The book is, essentially, a combined reprint of earlier works. The first half, Lost Books of the Bible, covers the New Testament. The second half of the book, The Forgotten Books of Eden, includes a translation originally published in 1882 of the "First and Second Books of Adam and Eve", translated first from ancient Ethiopic to German and then into English by Solomon Caesar Malan, and a number of items of Old Testament pseudepigrapha, such as reprinted in the second volume of R.H. Charles's Apocrypha and Pseudepigrapha of the Old Testament (Oxford, 1913).
