Physical Music Catalog Data Providers and Methodology

Garimpa.Club builds one linked catalog from online music-data providers, carefully curated reference datasets and reviewed catalog curation so collectors can find the exact physical edition they own or want. The exact release and work counts shown above are produced from the same published catalog used by the homepage and product, not from raw provider totals, import inputs or estimated database statistics.

What the Catalog Count Includes

The physical-release count includes distinct published editions manufactured on formats such as vinyl, CD, cassette, MiniDisc, shellac and music video. Digital-only downloads and streaming releases are filtered out before records enter Garimpa's provider-neutral catalog, linkage and publication stages.

Each published release is counted once. Provider records are normalized into shared fields and linked using stable source identifiers and release evidence such as artists, works, labels, catalog numbers, barcodes, countries, dates, formats and track relationships. Records that describe the same physical edition are merged into one Garimpa release while their source provenance remains attached. Different pressings, formats, countries, label editions or other materially distinct physical releases remain separate.

The catalog count is recomputed exactly from the published physical-only release model during each catalog publication. The “Catalog counted on” date identifies the build used for the displayed count. We do not add marketplace listings, retailer offers, raw source rows or approximate PostgreSQL table statistics to that number.

Source Coverage

Discogs

Discogs contributes detailed community-maintained metadata about releases, artists, labels, formats, tracks, catalog numbers, barcodes and country-specific editions. It is an important source for distinguishing physical pressings and packaging variations.

MusicBrainz

MusicBrainz contributes open identifiers and structured relationships across artists, releases, release groups, labels, recordings, places and external resources. These relationships help connect equivalent entities across sources without erasing provenance.

Wikimedia, Wikipedia and Wikidata

Wikimedia Foundation projects, including Wikipedia and Wikidata, contribute public knowledge, identifiers, reference links and historical context for artists, companies, works and releases.

Fanart.tv

Fanart.tv contributes artist and album artwork that makes catalog browsing more recognizable while remaining separate from release identity and count decisions.

Connected services

Services such as Last.fm and Spotify can connect a user's listening activity and music preferences to Garimpa features. They do not increase the published physical-release count unless a physical release is independently represented and linked in the catalog.

Curated Sources and AI-Assisted Curation

Garimpa also maintains carefully curated seed and reference datasets for catalog imports. These can represent additional documented sources beyond the online providers named above, including specialist discographies and release research prepared for catalog coverage. Every imported record remains provenance-bearing evidence: it is normalized into the same provider-neutral model, linked using shared catalog evidence, and must pass the same physical-only and publication-quality checks. Once data enters that neutral model, linkage and publication rules do not depend on which source supplied it.

AI-assisted curation helps reviewers identify potential coverage gaps, duplicates, conflicting facts and candidate links between artists, works and releases. These results are suggestions for investigation, not automatic catalog truth. They are reviewed against source evidence and catalog constraints before they can affect published data, and provenance is retained so accepted decisions remain traceable and correctable.

Provider coverage changes as sources improve, new releases are documented and linkage is refined. A source's presence does not mean every one of its records is published or that every physical release in the world has already been documented.

Catalog Sources and Shopping Providers Are Different

Catalog-data providers supply evidence used to describe and link artists, works, companies and physical releases. Shopping providers and collector listings supply current availability, price, shipping and purchase links. Shopping offers do not create catalog releases, and offer counts are never included in the physical-release count.

Retailer or seller identities are displayed only with offer-backed results. Garimpa does not sell those items directly and does not control a third party's inventory, price, fulfillment or terms. Some outbound shopping links are affiliate links, which may earn Garimpa a commission without changing the buyer's price. Listing a data source, retailer or seller does not imply sponsorship, partnership or endorsement.

How We Verify the “World's Largest” Description

The comparison was verified on July 13, 2026. We compare Garimpa's exact, dated count of distinct published physical releases with the largest publicly documented, release-level catalog counts available from comparable music-catalog services. We compare release entities with release entities: raw submissions, marketplace listings, sale offers, collection items, recordings, tracks and combined digital-plus-physical totals are not treated as equivalent physical-release counts.

For each comparator we retain its public source, the metric's definition and the verification date. If a service does not publish a count that can be isolated to release-level physical editions, we record that limitation instead of presenting an unsupported numerical comparison. Garimpa displays the superlative and the numeric proof together only while its exact eligible count exceeds the highest verified comparable public count. If the evidence or current Garimpa count is unavailable, the homepage falls back to a non-superlative description.

This method is designed to make the claim testable rather than permanent: counts and public methodologies can change, so the comparison must be reverified and the dated catalog proof must remain available.

Provenance and Corrections

Garimpa keeps source identifiers and links wherever available so catalog facts can be traced back to their contributing providers. Normalization and linkage create a unified browsing model; they do not transfer ownership of source data to Garimpa or erase the original communities' work.

This catalog would not exist without the people who document editions, identify credits, maintain open identifiers and preserve music history. If you find a release that is missing, duplicated or linked incorrectly, please contact us with the release and source references so we can investigate the published evidence.
