In order to preserve these materials and make them available to a wider audience, over the years some parts of the South Manchurian Railway Company (SMRC) collection have been microfilmed. At the Library of Congress, these microfilm items bear the standard designation “MOJ” (for “microform Japan”) as well as “MMTKK” in their call numbers. In the event that a title is available in both print and microfilm formats, the microfilm surrogate will be served for the sake of long-term preservation of the original. Please inquire via Ask a Librarian (link from box in left navigation) if you have a compelling reason to consult an original copy for research purposes. To view titles available on microfilm, perform a simple quick search for MOJ MMTKK:
Some, but not all, of these microfilmed publications from the Asian Division’s SMRC collection have been digitized and made available online through IDE-JETRO’s digital archive for prewar and wartime Japan-related materials (戦前・戦中期日本関係機関資料デジタルアーカイブ), accessible via the link below. Please note this resource is managed by the Institute of Developing Economies and Japan External Trade Organization (IDE-JETRO) and is not affiliated with the Library of Congress. If you locate an item from the Library's SMRC collection that indicates availability on microfilm, you can try searching the MOJ number on IDE-JETRO’s digital archive for prewar and wartime Japan-related materials.
For example, let us consider the following SMRC publication, which has been microfilmed as described above.
In the Library’s online catalog record for the above title, you will find that the field “LC copy” reads “MOJ 1800 MMTKK Microfilm”. This indicates that the item is available on microfilm and that the call number is MOJ 1800 MMTKK. To check whether a digitized copy of this microfilm is available on the IDE-JETRO digital archive for prewar and wartime Japan-related materials, you would perform a search for "MOJ1800". Please note that the IDE-JETRO digital archive does not include a space between “MOJ” and the following number within a microfilm’s call number, nor does it contain the MMTKK tag.
