NARA’s “Record Group Explorer” page at https://www.archives.gov/findingaid/record-group-explorer is a good place to get information on the number of digital images available in NARA’s online Catalog at https://catalog.archives.gov/ as well as the immense quantities of textual records that exist. As of July 2022, there are 179,271,436 images in the National Archives Catalog – or approximately 1.541% of 11.6 Billion textual records. (And that’s only textual records: that count does not include motion pictures, audio recordings, or data files).
Just over a year ago, in June 2021, there were 135,404,569 images in the National Archives Catalog, or about 1.175% of an estimated 11,524,683,948 textual records. That’s an increase of over 43 million digital images in a little over a year! Progress! (Back in June 2020, those numbers stood at 109,384,656 images or .95% out of an estimated 11,509,956,576 textual records).
Want to follow along and see what’s added? The “What’s New in the National Archives Catalog” page at https://www.archives.gov/research/catalog/whats-new links to record series to which digital images have been added – and may also highlight a few interesting items.
Digitization is a slow process. Records are typically one-of-a-kind items that may be fragile, bound into volumes, or otherwise unsuitable for “high speed” automatic sheet-feeding imaging systems. Records may require unfolding; removal of staples, pins, clips, and other fasteners; repair by trained records conservators; and other preparation for imaging, such as arrangement and new or improved description. Just consider the handling care required for the bundle of records shown below, which was just a small part of a small series, Records of Clerks, Wagonmasters, and Printers Employed at Various Posts, 1865-66 (National Archives Identifier 4707062), from Record Group 92, Records of the Office of the Quartermaster General.

This small series is fully digitized. Each individual file unit is now is described in the National Archives Catalog by the name of the commanding officer and his geographic location, which vastly improves discoverability by researchers: see the screen shot below, which shows a few of the 389 file titles.
