I've been involved  with the security sectors of different countries from before the term "Security Sector Reform" was invented,  and well before anyone  thought of using the term "governance". 

For much of that time, I have been irritated with what I see as the facile and superficial approach of many who write about SSR (a term I use as little as possible, and preferably not at all), and the unreality of a lot of things that are proposed.

My own writing, as well as the teaching and consulting I do, tries to anchor itself firmly in the reality of managing the security sector, based partly on my own experience around the world.

My two books on SSR can be found here, in downloadable form.

General articles on Security Sector Reform and Governance.
Articles on Security Governance in Africa.
Articles en Français.

And various presentations are here.

Last year, the Programme on Civil Military Relations in Arab States at the Carnegie Middle East Centre asked me, together with Maj Gen (rtd) Mohammad Farghal, to produce a Research Manual for young researchers in the Arab world trying to get to grips with the defence sector. It is now available in English and Arabic, and nearly all of it is relevant to researchers in other parts of the world as well.

The CMRAS site has a link to the Research Manual on this page and there is also a link that leads you to the Arabic version.
