Dear Ms. Frowein,
Thank you for posting your request on History Hub!
For a listing of microfilm publications, please visit National Archives’s Microfilm Catalog. The Microfilm Catalog provides options for keyword searches, advanced searches, and “Browse the Microfilm Catalog.” Clicking on the Browse button brings you to a list of publications, displaying 100 publications at a time. Small blue left and right buttons near the upper right hand corner or the listing allow you to move through the listing.
To bring up information about specific publications, click on the name of the publication. That will take you to a summary page. On the right hand side of the page will be a pdf file. Click on "View Important Publication Details." This is a listing of the contents of the rolls. Under the heading “Viewing Locations” is a list of National Archives facilities which have copies of the microfilm.
The Microfilm Catalog also allows you to purchase digitized copies of a microfilm publication, which would be mailed to you on DVD. Please note that the National Archives and Records Administration (NARA) has suspended reproduction and digitization services until further notice due to COVID-19. Orders will not be serviced until operations can resume safely. Once operations resume, document reproduction requests will be filled in the order in which they were received. We apologize for any inconvenience.
We suggest that you also review the Microfilm Publications and Original Records Digitized by Our Digitization Partners for a list of National Archives records that have been digitized by Ancestry, Fold3, and FamilySearch. In addition to the records available through our formal partnerships, some NARA microfilm publications have been uploaded to other online digital repositories such as the Internet Archives by the users of those websites.
Finally, some NARA microfilm publications may be available through other institutions which have purchased copies from NARA, however we do not have a listing of which publications are available at which non-NARA institutions. You may wish to check WorldCat and local, university, and state libraries and historical societies in your area.
We hope this information is helpful. Best of luck with your research!
Expanding upon Jason's response regarding the features of the Microfilm Catalog, there is now a column that indicates the digital availability of a microfilm publication through either our digitization partners or the National Archives Catalog (which is separate from the Microfilm Catalog).
If a microfilm publication was digitized and made available by a partner, the Digital Availability column will indicate that it is "Available by Partners." If a microfilm publication was digitized by NARA and is available in the catalog, the Digital Availability column will indicate that is "Available in the Catalog." When you click the publication title from the list view, the Publication Summary page will display. Under Digital Availability, there is a link to the National Archives Catalog. When you click on this link, it will take you to the digital copy of the microfilm publication available in the National Archives Catalog.
NARA is systematically digitizing microfilm publications that have not already been digitized by our partners so more and more microfilm publications are now available digitally. Additionally, as partner images of digitized microfilm publications are released from embargo, those images are being added to the National Archives Catalog and we update the Digital Availability column to indicate it is now available in the National Archives Catalog. So, check the Microfilm Catalog periodically for updated digital availability statuses!
