I seem to remember that one of our members posted the URL of the LOC NUCMC last winter(?) but a friend on another mail list reminded me to take a look again. This is the National Union Catalog of Manuscript Collections at the Library of Congress http://lcweb.loc.gov/coll/nucmc/nucmc.html Select <NUCMC Cataloging>, then select <NUCMC Online Cataloging> and when the search screen appears, enter <Blanchard> in the "Enter Term 1" box. As of today, there are 95 items that have Blanchard information. Here are a few lines from their FAQ page. The National Union Catalog of Manuscript Collections (NUCMC) is a free-of-charge cooperative cataloging program operated by the Library of Congress. On the basis of cataloging data supplied by eligible repositories to the NUCMC program, NUCMC catalogers create MARC (Machine Readable Cataloging) bibliographic records in RLIN (Research Libraries Information Network), a national-level database, describing collections held by participants, and establish pertinent name and subject authority headings. Descriptions and locations of the material are then available to researchers on RLIN throughout the United States and around the world. Here is an example, Record 34 of 95 returned.

Title: Blanchard family genealogical research papers, [ca. 1860-1980], [ca. 1940-1980] (bulk) As you know, Hartman has published numerous research notes on his wife's BLANCHARD line (Helen Blanchard Hartman).
