How would I be able to use the Dun & Bradstreet Credit Reference Book?

This title is known by a number of different titles - The Dun & Bradstreet Reference Book of American Business, Dun & Bradstreet Reference book, or the Reference book. The Library has an extensive print and microfilm collection back into the 19th century.  You can see an inventory at https://www.loc.gov/rr/business/duns/duns4.html.

Beginning in 1966, volumes are on-site at the Library, but if you need years before 1966, the volumes are in an off-site storage facility and you must request them 24 to 48 hours ahead of time. Some volumes are in microfilm format, roughly 1900 - 1924 (v.127-v.226) and those must be requested and used in the Microform and Electronic Resources Center (LJ-139).

If you have a current Reader Identification Card you can request via the online catalog. Since you must choose the location radial button specific to the time period you need, select Store Offsite for the years before 1966 or Jefferson or Adams Building Reading Rooms for those beginning in 1966. However, if you do not have an ID or are requesting multiple years, you will need to submit an Advance Reserve request but you will still need a Reader Identification Card to enter a reading room and use the collection.
