The literature of Nongovernmental Organizations has been connected to the increasing and  escalation of INGOs’ roles in human rights and relief matters of INGOs connecting to governments and donors and also with the social activities. In general, the INGOs’ literature has concentrated on NGO roles in the relief and humanity industry and also developmental practices.

By contrast, the non-profit literature of INGOs has ordered its primaries preferences  to  some  extent  differently.  This  matter  has  had  considered theoretical requirements like the different definitions for the presence of the third section and policy fields like increasing the contractions. It has focused on services and also on welfare organizations clearly more than advocacy and cultural and social changes of organizations and therefore has given an upper priority and primaries than the  NGO  literature to the structural and managing subjects of the organizations.

According to  the  other  point  of  view,  some  subsidiary  subjects  have hardly been created in the scope of NGOs literature. There are also a number of other differences. The INGOs literature has seen INGOs as one of the key actors  in  processes  of  humanities  subjects  and  development  field  (for instance  the  peace  between  nations)  alongside  the  state,  governments, private agencies and also internal and external donors.
