Disclaimer & Correction Policy

BIAN compares publishers using public digital visibility and activity signals. It is not a certification, endorsement, blacklist, legal opinion, or literary quality verdict.

This page states the boundaries of the benchmark clearly: what it measures, what it excludes, and how the correction path works when public data is inaccurate or outdated.

Benchmarking Scope

The index uses publicly available, verifiable data only.
Scores and A1-A4 tiers reflect relative position within the observed dataset at the time of update.
Absence of public data does not necessarily indicate poor quality, inactivity, or weak legal standing.
Quartiles are comparative benchmarking bands, not guarantees of quality, legal standing, or operational strength.

Excluded Inputs

Private operational data
Non-public financial estimates
Subjective reviews or reputation opinions
Editorial judgments about literary merit

Correction And Data Review Workflow

A publisher or user submits a correction request with a public source URL.
The request enters an admin review queue.
Editors validate the claim against public evidence.
If validated, the change may be applied to the live dataset with a timestamped audit log.

Catalog-level corrections should include title-level details such as ISBN, publication year, or product page URL when available.

Limitations

Public websites and catalogs may be incomplete, blocked, stale, or inconsistent across publishers.
Publishers with limited public web footprints may appear with lower confidence even if they operate effectively offline.
Publisher names, imprints, branches, and translated titles may require manual review to avoid confusion.
