Encyclopedia reference
Sources & trust.
The encyclopedia uses a source hierarchy so readers can distinguish current tested guidance, primary historical records, secondary references, manufacturer material, and informal or rebel-canning sources.
Highest-priority sources
Start with the strongest evidence.
National and university authorities
Government, university, and academic home-canning guidance with documented testing or recognized institutional responsibility.
Extension services
Publicly funded food-preservation programs and Cooperative Extension guidance tied to research-based home
Manufacturer guidance
Consumer home-canning guidance from jar, lid, equipment, or preservation brands when the testing basis is documented.
Primary historical sources
Original books, bulletins, manuals, archival publications, and other firsthand home-canning records preserved in context.
Additional sources
Unique information can still matter.
Reputable books, preservation organizations, regional institutions, experienced home-canning writers, blogs, community archives, and rebel-canning sources may be included when they contribute unique recipes, historical evidence, regional practice, provenance, or context. Inclusion does not imply equal source reliability or current safety.
Duplicate handling
Substantially duplicate recipes are grouped into one canonical record. The highest-trust source is preferred as the primary reference while alternate citations and meaningful provenance remain preserved.
Source metadata
Source name, URL, publication title and date, page number, archive URL, country, region, original language, translation status, and source reliability are retained where available.
Project boundary
Commercial canning is excluded.
