The 17th century monument of Chausath Khamba was laid open for the three-day event, with top government publishers offering their collections to residents of one of Delhi's oldest living areas.
Inaugurating the exhibition, Commissioner Neeraj Kumar said it was part of Delhi Police's attempts to connect to people and asked officials to instill confidence in the people so as to secure their cooperation.
"To give a form to community policing we have started such an initiative. As part of our 'jan sampark' programme we will be meeting people at neutral venues, listen to them and address and dispose of their complaints," he said.
Kumar also admonished investigating officers who do not keep complainants updated about the developments in their cases.
"I have noticed instances where cases have long been solved and materials recovered but the complainants have not been informed.
Investigating officers should be in constant touch with complainants. It is not the right approach to receive a complaint and not return back to the person," he said.
The event at the Nizamuddin basti that saw the presence of Delhi Police's top brass was described as an attempt to augment ties with residents of the locality.
"Last year, in a similar attempt we inaugurated a public library in Jamia Nagar. The onset of new technology of email and Internet is a challenge to which the written word has to adapt and evolve," said Congress MP Sandeep Dikshit.
The exhibition will witness a host of activities over the next three days, including storytelling sessions and workshops on presenting stories through dance and drama.
The activities are primarily aimed at children and to promote the culture of reading and expressing in them.
"This also indicates how police is changing over time and is trying to increase confidence with the people," Assistant Director of National Book Trust, Rakesh Kumar said.
Thousands of books from Rashtriya Bal Bhawan, Sahitya Akademi, National Council for Promotion of Urdu Language, and Ghalib Academy, have been displayed at the serene compound of Urs Mahal, adjoining the Chausath Khamba monument.
The book fair is as much an attempt to disseminate reading culture among people, especially among the section of slum dwellers, low income groups and children of marginalised sections, as to create an atmosphere of mutual trust.
"Besides crime control, prevention an detection, our attempt is to keep Delhi safe through community policing," said Additional Commissioner South East, Ajay Chaoudhary.
