Also can provide technical assistance.
The composting toilet system book :a practical guide to choosing, planning and maintaining composting toilet systems, a water-saving, pollution-preventing alternative, DavidDel Porto and Carol Steinfeld, 2000, Center for Ecological Pollution Prevention, White River Junction, VT. Can be purchased at several outlets including http://www.amazon.com and http://www.ecological-engineering.com/ctbook.html This is the bible of sorts for composting toilets with a thorough description of processes and options. It is mostly geared, however, for more developed countries with connections to commercial products. Might be a good place to start if you have limited internet access. Check out the excerpts list below and in other sections hosted by oikos.com.
This is a lengthy excerpt from The Composting Toilet System Book listed above. Very useful general information.

A lengthy general article with a good overview. Also describes some of the different approaches of the commercial manufacturers. Has some installation tips (for commercial type products) and information of greywater.
A list of sources and links for composting toilets, but most are of a more general nature.
This is the website for ReSource – Institute for low entropy systems “is an independent, nonprofit organization that works in partnership with communities in English and Spanish speaking countries to protect public health and the environment. We support non-depleting, non-wasting, non-polluting methods and technologies for sustainable development.” They work with communities on ecological sanitation issues emphasizing composting toilets. The site has some good information, a thorough list of links and resources and even some photos of composting toilets they have assisted with. Might be a partner if working in some Latin American countries.
This is the Mexico based website of SIRDOS – Grupo de Tecnologia Alternativa. It is a general site for alternative technologies, but includes sections and information on composting toilets.
Website for BioCycle – Journal of Composting and Organics Recycling. Has some archived articles on composting, but most are not technical guides – just description and advocacies pieces.

An excellent set of technical briefs in PDF format originally produced by the Development Information Center of USAID.
There are three specific to composting toilets:
Designing Compost Toilets (SAN.1.D.6)
Constructing Compost Toilets (SAN.1.C.6)
Operating and Maintaining Compost Toilets (SAN.1.O.6)
There are many other great briefs at this site concerning rural water supply and disease.
This site contains access to several technical briefs considering rural water supply and sanitation. The one of interest for composting toilets is #63 – Using Human Waste which provides some composting toilets guidelines.The whole series together can be obtained in a print version from WEDC at http://www.lboro.ac.uk/wedc/publications/rw.htm
