Data Repositories

A data repository/depository refers to the actual website where raw data files are stored and can be accessed. Researchers pay or have contracts with institutions to store the microfilm/raw files/primary data in these huge computer storage areas. They are usually associated with a university and store only data but not articles or papers.
