The Library of Congress has added SQLite to its roster of Recommended Storage Format for digital datasets. The open‑source, file‑based SQL engine now sits alongside XML, JSON and CSV as a preservation‑grade option. Archivists cite SQLite’s self‑contained file structure and widespread adoption in applications ranging from mobile apps to embedded devices.

When the LOC evaluates formats it looks at disclosure, adoption, transparency, self‑documentation, external dependencies, patent risk and technical protection mechanisms. SQLite scores well because its full specification is publicly available, it runs on virtually any operating system, and a database file can be inspected with a plain‑text editor. Those traits align with the agency’s preservation priorities.

By endorsing SQLite, the Library of Congress signals that lightweight relational databases meet the same durability standards as traditional text‑based formats. Researchers and developers can now cite a federal preservation authority when choosing SQLite for long‑term storage, reducing the need for format conversion later. The move gives the database a credibility boost that may influence institutional archiving policies.

Institutions already using SQLite for active projects can now archive those files without additional packaging layers. Because the format requires no proprietary codecs and its license is permissive, long‑term custodians avoid legal and technical hurdles. The LOC listing effectively codifies SQLite as a safe, future‑proof container for scientific and governmental data.
