This is a library for libraries in Chicago which collects primary resources on a scale and at a depth which no one library in America could afford or would need to own on its own. We borrow materials from CRL for our patrons via Document Delivery. Their catalogue is on the internet. A number of sources on this bibliography in the MICROFORMS section are held there, not here at M.S.U. To find out what is in these sets, check the CRL online catalog.
