So many scholars praised the original edition of Bhagavad-gita As It Is. Have any praised the revised edition? Not that we know of. Why not? It must be because they haven't accepted it. That is, they accepted the first but rejected the second. Why else would they not have come forward to praise it?

The answer is simple:

Scholars have ceased coming forward to offer praises because we've ceased asking scholars to do so.

In the mid and late 1970s, devotees working with the BBT and its Library Party were exceedingly active in approaching academics for reviews of Srila Prabhupada's books. Devotees went from university to university, college to college, in America, in Europe, and elsewhere, collecting orders for Srila Prabhupada's books and soliciting reviews.
Similarly, Srila Prabhupada's disciples like Subhananda Dasa made a full-time service of cultivating relationships with academics, arranging for reviews, and so on.

After the Library Party crisscrossed America and Europe, it eventually disbanded. (How many times can you approach the same libraries to buy the same books?) The vigorous efforts to solicit reviews also ceased.

And you don't ask, you don't get.

Would approaching newer scholars for reviews be a good idea? Sure, why not? (No one is doing it, so the service is available.)

Meanwhile, at www.bbtedit.com/testimonials you can see comments by a devotee scholar, Garuda Dasa (Dr. Graham Schweig), heartily endorsing the second edition.
