Curtis, Glenn E. "Religion." In Turkmenistan: A Country Study. Washington: GPO for the Library of Congress, 1996, http://countrystudies.us/turkmenistan/14.htm.

Curtis discusses Sufi shaykhs and their role in syncretic Islamic practices, the authority of övlat lineages descended from the four Caliphs who succeeded Muhammad, Soviet atheism, and independent control of Islam.  See also his Bibliography which contains over 90 entries, mostly published in the 1990s and many of them U.S. or World Bank government agency reports.  Some of them relate to Islam in Central Asia. 

Sections: History and Structure; Religion After Independence.

Tabyshalieva, Anara. "The Kyrgyz and the Spiritual Dimensions of Daily Life." In Islam and Central Asia: An Enduring Legacy or an Evolving Threat?, edited by R. Z. Sagdeev and Susan Eisenhower, 27-38. A Center for Political and Strategic Studies book. Washington, DC: Center for Political and Strategic Studies, 2000.

Tabyshalieva's first two sections briefly discuss sacred sites in Kyrgyzstan, including Suleiman's Mountain in Osh.  The third and fourth sections discuss religious pluralism.  She divides Kyrgyzstan into three parts: Bishkek with Christian groups; the North with "traditional" Islam; and the South with "strict" Islam.  The section on women briefly discusses the veil, polygamy, abortion, and male-domination.  The last section discusses political issues in other Central Asian countries.  In conclusion, she argues that Central Asian states should be more transparent and open with religion in order to prevent conflicts.  Tabyshalieva's chapter covers a lot of material, but not in depth.

Privratsky, Bruce G. Muslim Turkistan: Kazak Religion and Collective Memory. Richmond UK: Curzon, 2001.

Privratsky's book is a good ethnographic survey of contemporary Islamic practice among Kazakhs in Turkistan, Kazakhstan. It discusses, among other things, Sufism, lines of ancestry traced to the first century of Islam, observance (or non-observance) of the five pillars of Islam, shrine visitations like that of the Yasawi Mausoleum, veneration of ancestors, and healing arts. There are interesting discussions about pre-Islamic influences of contemporary religious practices and what are true Islamic practices.
