Challenge 24 in the 52 Weeks to Better Genealogy series asks us to learn about the differences between the Dewey Decimal Classification System and Library of Congress Classification System. Charts comparing the two systems are found at Wikipedia as well as at the Randolph C. Watson Library at the Kilgore College Library in Kilgore, Texas.
For this challenge I looked at several titles in the OhioLink card catalog, which features the holdings of several Ohio academic libraries.
SANDUSKY THEN AND NOW, which provides genealogical information about many of Sandusky’s early residents of German descent, is found at several Ohio libraries. Mount Union College has this title filed under the Dewey Decimal System with the number 977.122, while the other three libraries have used the Library of Congress Classification System with call numbers beginning with either F499 or F486.
A GENEALOGIST’S GUIDE TO DISCOVERING YOUR GERMANIC ANCESTORS, by Chris Anderson, has a Dewey Decimal call number of 929.108931, and Library of Congress classification that begins with E184.G3.
THE CENTENNIAL HISTORY OF ERIE COUNTY, OHIO, by Hewson L. Peeke is filed under 977.122 in the Dewey system, and this book’s Library of Congress designation begins with F497.
The book entitled THE TOWN OF MILAN, by James A. Ryan, has a Dewey Decimal call number of 977.122 and a Library of Congress classification that begins with F499.M64.
For me, I am just delighted to be able to locate these titles, no matter what their call numbers are. In this age of electronic card catalogs, I can access card catalogs from hundreds of different libraries on my home computer, and if necessary, plan a trip to the library where most of the titles can be located. My personal favorite "road trips" to libraries include: the Library of the R.B. Hayes Presidential Center in Fremont, Ohio; the Ohio Genealogical Society Library,soon to be located in Bellville, Ohio; and the Allen County Public Library in Fort Wayne, Indiana. Happy searching!
