You can find a partial list of world records at GuinnessWorldRecords.com or in a physical reference book called "The Guinness Book of World Records," published annually.
Guinness World Records is the primary international authority responsible for cataloging and verifying world records. The company employs official record adjudicators to determine the authenticity of attempts to set or break records. There are more than 40,000 current records in their database, so due to space constraints, only around 4,000 records are published in "The Guinness Book of World Records" each year. Guinness World Records currently displays around 15,000 records in their online database, which they update every week.
