The Ensign and Liahona magazines now publish some articles in digital-only format. In addition to the articles in the printed magazines, other articles are available online at ensign.lds.org and liahona.lds.org, and in the Gospel Library app.
For example, the June 2018 issue of the Ensign has a number of articles about the 40th anniversary of the 1978 revelation on the priesthood. There is an additional personal experience titled “How Could You Be Mormon?” that is available in the digital-only collection.
The digital-only articles are also listed on a separate page for your convenience:
