The Demand Purchase program is a key service through which CRL acquires materials identified by researchers that may be costly, difficult to obtain, or beyond the scope of local collection policies. Patrons at CRL institutions may request materials from CRL in specific categories--foreign dissertations, newspapers, and archival material--with a maximum expenditure of $2,000 per patron per year.

CRL's Demand Purchase: Archives program is particularly useful for scholars seeking to access critical primary source collections retained by national archives, government bureaus, or other organizations. Some recent acquisitions by CRL through this program illustrate the depth, diversity, and scope of CRL's collections.

The Community Analysis Reports and Community Analysis Trend Reports document an effort by the WRA to obtain an understanding of the social background of the evacuees and their reactions to conditions in the relocation centers.
