Research Methodology

LitBuy Spreadsheet is an independent research directory. We record the visible source URL, displayed price, category, link status, and the date each record was checked.

What a check means

A link marked as checked was accessible on the stated date. This does not verify authenticity, inventory, seller reliability, product quality, shipping cost, or delivery time.

Corrections

Records are reviewed when a source changes or a factual correction is received. Material corrections should include the affected URL and supporting evidence.
