Web and academy
I find Wikipedia a fascinating thing to watch. Sometimes you need to know where to look. The article on Donmeh contains some (allegedly) first-hand reports of the community today - but they're hidden in the Discussion section. Since people don't usually admit freely to belonging to a sect equally reviled by Jews and Muslims, it's not so easy to find descriptions like that.
A random Google search can often also be an important source of information, and my example for today is another manuscript sold off at the Montefiore auction is on the market again.
