National Review's "Investigation" of Documents Housed in the Richard J. Daley Library
Libraries are large and complex organizations. The communications made to Stanley Kurtz, National Review (NRO) contributing editor by staff of the University of Illinois – Chicago (UI-Chicago) about the availability of the requested collection, especially comments by a part-time graduate student, are not prima facie evidence of a coverup or conspiracy. Rather, the allegations provide evidence on the state of one specialized collection in a large library with millions of individual items that is not intimately known in its entirety at the initial points of public contact.
