Research & attribution
How to cite TexasDefined county, property-tax, data, travel and sports reference pages, Painted Churches resources and other maintained guides, including canonical URLs, source precedence, date context and machine-readable resources.
Cite the clean TexasDefined canonical URL rather than a search, filter, preview, tracking or download URL unless the downloadable file itself is the object of the citation.
When a claim comes from a government record, agency, park authority, church or parish, venue, event organizer or public dataset, cite that controlling source alongside TexasDefined when the distinction matters.
Include the page's source-check, verification or data-as-of context when facts can change. Keep any visible completeness, planning, designation or event-day caveat with the cited result.
Suggested format
Texas Defined, “Page title,” canonical page URL, verification or modification date when shown, accessed on your research date. For deadlines, eligibility, official boundaries, closures, fees, current government records, church access, event schedules, ticketing, parking, gate times or venue-entry rules, include the linked official source as the controlling authority.
When a reference page offers a CSV, JSON or checklist distribution, use the canonical HTML page for context, methodology and caveats; use the downloadable file when you need the machine-readable or printable distribution itself.
Things That Define Texas source hierarchy
Use the canonical Things That Define Texas collection or chapter when citing the 250-item editorial set, chapter membership or TexasDefined's explanation of why an icon belongs in the collection.
When an entry resolves to a destination or evergreen deep dive, use that deeper guide—and its linked official or institutional sources—for the underlying history, visitor facts, cultural context or current operations.
Use the Texas Blue Norther guide and its Handbook of Texas source for terminology and cultural history. For a current front, thunderstorm, tornado, hail, lightning or flood decision, use current National Weather Service forecasts and warnings as the controlling authority.
The CSV and JSON are generated from the same 250 editorial records and canonical-link resolver. Cite the human collection for context and methodology unless the machine-readable distribution itself is what you are analyzing or redistributing.
Top-25 source hierarchy
For current admission, reservations, hours, closures, accessibility, permits and operating rules, use the attraction operator or responsible public agency identified as the controlling source on the destination guide.
Government agencies, universities, UNESCO, preservation bodies, conservation programs and accountable institutional sources can support history, science, designation or other durable context, but they do not override the operator's current instructions.
Visit length, effort, exposure, planning level, family fit, first-time value, itineraries and road-trip structures are labeled TexasDefined editorial assessments. Cite the methodology page when those fields are material to your use.
Painted Churches source hierarchy
Use the linked Texas Historical Commission or National Register record when a claim depends on formal historic designation, reference number, architect, listed date or property identity.
Use the responsible parish, congregation, diocese or official local tour source for current access, services, closures and visitor rules. Historic designation does not guarantee a church is open for sightseeing.
Use the church-specific source trail plus the relevant technique, symbol, person, heritage or preservation authority page when a claim depends on TexasDefined's broader evidence graph rather than a formal designation.
Use the Then & Now page and linked archival item when discussing visual change. The archival record controls historic-image provenance; a current Commons or other reusable image controls the modern image license.
For statewide counts, use the dedicated count explainer; for inclusion/exclusion decisions, use the census; for artist or symbol questions, cite the canonical entity page rather than a generic church-list page. Do not collapse the Schulenburg touring cluster, the formal National Register decorative-interior group and the broader statewide tradition into one unlabeled number.
Maintained resources
County comparisons, city-to-county relationships and the Texas data catalog.
Statewide explanations, county comparisons, appraisal districts, deadlines and action guides.
A maintained 250-item cultural reference collection with explicit inclusion rules, exact deeper-guide relationships and shared CSV/JSON distributions.
Maintained comparison and authority layers for moving, parks, water destinations, small towns, road trips and attractions.
A 27-church verified heritage-reference collection with canonical entity pages for decorative techniques, symbols, people, cultural communities, preservation, archives, routes and research methodology.
Verified venue directories and comparison pages for Texas stadiums, arenas, ballparks, racetracks and sports-trip planning.
Machine-readable discovery
The citation manifest lists maintained canonical factual-reference targets and trust attributes. The llms.txt route describes TexasDefined's entity graph, retrieval rules and preferred reference resources. These are discovery aids; the human-readable page and its linked official sources remain the evidence layer.
Reference notes
The citation guide explains how TexasDefined reference pages relate to their underlying official and public-data sources. It is a policy layer rather than an independent factual dataset.
