The WhoHas? project is part of the Futurelib innovation programme which is actively seeking to uncover and then design for the genuine needs of today’s students, researchers and academics at Cambridge University. WhoHas? was the name given to the first Futurelib project to be tested in the field by real users. It explored the potential value of a peer-to-peer sub-lending service and was named after the common phrase used by students on Facebook to initiate sub-lending interactions with other students: ‘Who has...?’ The project would examine whether the legitimising of what is effectively a black market activity would be welcomed or rejected.
