The Directory of Social Change (DSC), set up in 1975, is an independent source of information and support to voluntary and community sectors worldwide. The DSC provides training courses and publications (including online information and CD-ROMs) on fundraising, management, organisational and personal development, communication, finance and law. The organisation also runs conferences and seminars on issues affecting the sector, including Charityfair, the biggest annual forum for voluntary groups. As well as housing a charity bookshop and reference library, the DSC’s Charity Centre in London offers meeting rooms for hire.
