Most residential and general organizational telephone directories are not cataloged by the Library of Congress, even though the Library maintains a large collection of foreign and domestic directories. We have therefore compiled this list of directories from the former Czechoslovakia and from Slovakia as a finding aid for our staff and researchers. The uncataloged directories listed in this guide reflect holdings as of 2014.

In addition to the uncataloged directories listed in this guide, the Library also holds a handful that are cataloged and may be requested using the online catalog. To locate these directories, search the Library of Congress Online Catalog using subject keywords such as "Czechoslovakia" or "Slovakia" or the name of a city, and "directories". In addition to telephone directories, this kind of search also yields business/address directories from Slovakia, and Transcarpathian Ruthenia, or from Czechoslovakia.
