In 1999 on MG Road, it was more likely a roadside vendor with pirated books, Higginbotham, or unlikely, Gangarams. Blossom’s (Church St) wasn’t yet open IIRC.

Late 90s and early 2000s, I recall that Intel Inside, Lee Iacocca’s book, Who Moved my Cheese, Seven Habits of Highly Successful People, Jack Welch’s book, etc were commonly sold, in addition to the latest novels. I even remember buying Sylvia Nasar’s A Beautiful Mind (was popular because of the movie then) from a roadside vendor.
