I need help regarding books for economic geography and regional geography.

Everyone here has suggested to go for Economic geography by fazl karim khan. I checked that book and its completely outdated its last edition was published in 1990s.

Instead, there is another book by fazl karim khan by the name of "Commercial Geography" for intermediate class. Should I go for it? its updated with latest figures.

And any recommendation for regional portion which covers south asian and pakistan completely?
