The DPC's 'Bit List' of Digitally Endangered Species is a crowd-sourcing exercise to discover which digital materials our community thinks are most at risk, as well as those which are relatively safe thanks to digital preservation. By compiling and maintaining this list over the coming years, the DPC aims to celebrate great digital preservation endeavors as entries become less of a ‘concern,’ whilst still highlighting the need for efforts to safeguard those still considered ‘critically endangered.’
