The Grundbuchblätter Diverse: Böhmen, Mähren, Schlesien are the basic service sheets for Austrian army personnel from Bohemia, Moravia, and Silesia. Data shown includes year of birth, place of birth, a personal description, and record of service. In 1820, these basic service sheets replaced the muster rolls as the registers for Austrian military personnel.

Personnel sheets for soldiers born before 1865 are kept in the War Archive in Vienna. Records for soldiers born 1865-1910 and officers born 1865-1905 can be found in the Military History Archive in Prague, although most records for soldiers born 1887-1900 were destroyed. Personnel sheets for soldiers born 1911-1920 are stored in the History Military Archive in Bratislava, Slovakia and records of soldiers born 1921-1974 and officers born 1905-1974 are stored in the Military Archive Central Registry in Trnava, Slovakia. Personal sheets for soldiers who served after 1992 are kept in the AČR (Administrative Archive of the Czech Army) in Olomouc. In 2004, mandatory military service was abolished in the Czech Republic.

The Grundbuchblätter Diverse for soldiers born approximately 1820-1864 were reproduced on 662 rolls of microfilm, which have subsequently been digitized and are available for viewing online. They are divided into two series: Diverse (454 rolls) and Diverse/I (211 rolls). Since there is no rule how to determine if the record is in Diverse or Diverse/I, both series must be searched for each surname. Both series are strictly alphabetical by surname and given name. It's necessary to check for all possible spellings of the names. For example, if your ancestor's name was Jan Sedy, you need to check for Jan, Johann & Joannes and Sedy as well as Schedy and Szedy. Since the Grundbuchblätter Diverse is arranged alphabetically, it's not necessary to know the regiment in which your ancestor served.
