Question: What type of publication medium are The Christian Century and Civil War Times?

Reaching for the Invisible God: What Can We Expect to Find?  is a book written by Evangelical Christian writer Philip Yancey and published by Zondervan in September 2000.  The popularity of Yancey's 1997 book "What's So Amazing About Grace? " helped boost the sales of "Reaching for the Invisible God" to the point that it appeared on religion bestseller lists immediately upon publication.  Within a month, Zondervan reported sales of 94,000 copies.  While preparing to write the book, Yancey asked several people how they knew that their trust in Jesus had changed their lives, and one Christian radio host responded, "I have no trouble believing God is good.  My question is more, what good is he?  ... I cry out to God for help, and it's hard to know just how he answers".  "Reaching for the Invisible God" includes discussion of Yancey's bad experiences of growing up in a very judgmental church, a theme that he had previously discussed in "The Jesus I Never Knew" and "What's So Amazing About Grace?"  and later returned to in "Soul Survivor".  In November 2000, "Reaching for the Invisible God" became the first print book to be released as an e-book by Zondervan, appearing on Microsoft Reader.  The book received the 2001 "Christianity Today" Book Award in the spirituality category.  A "Topeka Capital-Journal" review called "Reaching for the Invisible God" "another accessible book from Yancey on a theologically complex subject for those who believe in God, and those who aren't sure if they can".  David Crumm of the "Lincoln Journal Star" wrote a review of the book and said that Yancey's honesty about his own personal pursuit of God is remarkable.  In a 2001 review in "The Christian Century", Peter Marty writes that Yancey "succeeds brilliantly [in] tell[ing] the truth about the Christian life 'without overselling it'". <SEP>  It was established in 1962 by Robert Fowler due to centennial anniversary interest in the Civil War in the United States.  It focuses on both battlefield strategy and tactics and the social and economic conditions of the time, as well as the aftermath of the Civil War on the present. Civil War Times (formerly Civil War Times Illustrated) is a history magazine published bi-monthly which covers the American Civil War. <SEP> Children of Memory ("Niños de la Memoria") is a documentary film produced and directed by Kathryn Smith Pyle and Maria Teresa Rodriguez.  From 1980–1992 about 75,000 women, men and children died and disappeared during El Salvador’s civil war.  It was known fact that most adults would be assassinated, but no one knows exactly what happened to the children.  The film follows Pro-Busqueda investigator, Margarita Zamora, as she searches the countryside asking eyewitnesses to recall what they remember from war times.  As Pyle and Rodriguez tell the personal account of Zamora’s search for her 4 siblings, so do they also tell the story of American Jaime Harvey, who was adopted from El Salvador in 1980, and Salvador Garcia, a farmer who continues the search for his daughter Cristabel.  Their efforts to find their family members are challenged by the lack of access to Salvadoran military war archives. <SEP> The Christian Century is a Christian magazine based in Chicago, Illinois.
