Biographical dictionaries, such as Dictionary of Catholic Biography, and subject encyclopedias, such as Encyclopaedia Judaica, limited to one religious tradition can be used to find biographical sketches.
Library of Congress call number ranges for each religious tradition can be used to find subject dictionaries/encyclopedias, and the specific call number ranges allocated to biography can help locate biographical dictionaries for that religious tradition in the reference collection.
Below are some examples of useful subject and biographical dictionaries as well as some Library of Congress call number ranges that can be used to find additional resources.
