"This database was produced from a microfilmed copy of an alphabetical card file containing local cemetery records and newspaper death notices gathered by the staff of the Cleveland Public Library. A small collection of records from the Cleveland Bureau of Vital Statistics and some indexed items from the Annals of Cleveland were also part of the original card file and are also included in the database. The newspaper source material consists of paid notices which were published in the following newspapers: Cleveland Plain Dealer, 1850-1975, the Cleveland Herald, 1833, 1847-1848, 1876, 1878-1879 and the Cleveland Press, August 16, 1941 - 1975."
