Local History Index in the Genealogy and Local History Department
About 60 years ago, a group of librarians resolved the problem of poor or no indexing in dozens of older Hamilton County history books by reviewing these sources word for word and creating index cards listing people, places, businesses, historic events and general topics. Each card provides the book title, call number and page number for locating the information.
