It is for the use of ADB staff and consultants, borrowers/clients and executing agencies, private sector clients, and social safeguards practitioners, including non-government organizations and civil society. The draft Sourcebook is a working document and will be revised from time to time. As such, any comments on the contents and style of the draft Sourcebook are highly welcome.
