Blank book measuring 6¼ × 4 × ⅜ inches (16 × 10 × 1 cm). The book contains seventy-six leaves in six gatherings. The first leaf of the first gathering is glued to the front board, and the last leaf of the last gathering is glued to the back board. ’s entries in the book are in brown ink. The volume contains stains and mold damage throughout. The volume’s limp case binding is supported by two strips of vellum tape along a hollow-back spine. After the book was bound, brown leather—possibly sheepskin—was pasted along the boards and spine of the book. Richards inscribed “Pocket Companion” in ink on the cover of the volume. He similarly wrote “W Richards Pocket companion written in England” on the recto of the second leaf. The majority of the volume’s content is a copy of apostle ’s “Book of Revelations,” which contains several JS revelations and discourses as well as a sermon by . Richards copied the content at some point after 13 January 1841, when Woodruff arrived in for a proselytizing mission with Richards and others. Richards next wrote nearly thirty pages of scriptural notes under the heading “The Subject of the Dispensation of the fullness of Times” and then copied additional instructions from JS, which he likely received from another missionary, possibly . Afterward, Richards copied selections from JS’s Bible revisions for Genesis and Matthew, followed by a passage from a revelation not included in Woodruff’s “Book of Revelations.” Richards apparently completed making entries in the volume by 20 April 1841, when he boarded a ship to leave England. After Richards became church historian and recorder later in the 1840s, this volume and his other personal papers were included among the archival holdings of the church. An early inventory of church records includes a reference to “Drs. private books & Papers,” which likely included the “Pocket Companion.” The volume contains archival and use marks throughout, suggesting that at some point material was copied from the “Pocket Companion,” likely by staff in the Church Historian’s Office in the mid-1850s. The use of the volume in the Church Historian’s Office suggests that the volume has been in continuous institutional custody.
