I will admit to only thinking about this for a few days. However, it seems to me that the Harvard material is rather narrowly focussed both on a temporal and on a topical level. I am an admirer of Froomkin's essays, and have published at least one of them (in the distant past when Matrix News was published). I haven't really looked at Ruling the Root, because I was turned off by Dave Crocker's review in IPJ. But, anyway, as it appeared in 2002, I imagine it contains little of the recent Verisign/Netsol "business." However, I should most likely give Mueller more leeway, as I really liked his telephony book. Peter
