I am glad to see this set is available once again. I had an old edition years ago which I studied extensively. It's not to be matched for studying arabic, persian and middle eastern religion, science and literature with the exception perhaps of the fine cambridge history of arabic literature volumes.
As the price is steep, I have had to put it on my wish list.
Browne travelled in Persia in the 19th Century and left us his "Traveller's Narrative" which contain important information on the early days of the Bahai'i (sp?) movement.
Again,highly rated. Belongs on the shelves of every student of the east, the esoteric, the sublime.
