Mission rules prohibit missionaries from reading just anything while they serve. They are not supposed to read newspapers or novels, for example, nor are they to read from many of the voluminous Church books that are out there. Here is a list of the approved reading material.
- The Scriptures and Church study aids
- The Preach My Gospel Manual
- Official Church magazines (The Ensign, Liahona, etc.)
- Other lesson manuals and official Church materials
- The Church News
Books: The Missionary Reference Library
Missionaries are also allowed to bring the following books with them for reading (sold at as the Missionary Reference Library at the LDS eStore and Distribution Centers):
- Jesus the Christ, by James E. Talmage
- Our Heritage: A Brief History of the Church of Jesus Christ of Latter-day Saints
- Our Search for Happiness, By M. Russell Ballard
- True to the Faith
Any exceptions to this reading list would have to be approved by your mission president.
