The shop was inaugurated on February 5 by Sahitya Akademi chairman Vishwanath Prasad Tiwari.
It will offer 15 per cent discount on books in Indian languages published by the Akademi to commuters.
"The idea of this initiative is to promote Indian literature by providing quality and also to cultivate reading habits among Metro commuters and employees," a statement from the DMRC said.
Limited edition of DMRC publications will also be made available for sale from the shop.
Akademi is dedicated to the promotion of literature in Indian languages.
DMRC has already opened two bookshops in association with National Book Trust (NBT) at Kashmere Gate and Vishwavidyalaya Metro stations in 2014.
