CELL Foundation is a not-for-profit organization founded by socially committed youth, working across diverse aspects of human development through creative, inclusive, and community-driven initiatives. Registered under the Indian Trusts Act in March 2023 and listed on the NITI Aayog's Darpan portal, the Foundation promotes grassroots movements led by people — especially the youth — to foster sustained and inclusive change.

The Book in Hand Campaign is a flagship initiative by CELL Foundation. It is a youth-led social initiative that has been running consistently since August 2023, committed to creating a community where every individual has the opportunity to learn and grow. The campaign operates Free Community Libraries across Delhi to ensure that books and knowledge are freely accessible to all — without any barriers. Currently, there are six Free Community Libraries, including two dedicated to children from slum communities.
