Although this website is about resources and travel concerning Israel/Palestine, we acknowledge that there are other countries which could be called a part of the Holy Land. They contain sites from the Bible and early Christianity.
Two books especially helpful if you are traveling in other Middle Eastern countries are:
Women of Bible Lands: A Pilgrimage to Compassion and Wisdom by Martha Ann Kirk. Collegeville, MN, Liturgical Press, 2004.
Who Are the Christians in the Middle East? by Betty Jane Bailey and J. Martin Bailey. Grand Rapids, MI, William B Eerdmans Publishing Company, 2003.
