More than 66,500 FamilySearch volunteers around the world helped index and arbitrate records from July 20 at 6 p.m. to July 21 at 5:59 p.m. as part of the Worldwide Indexing Event and also helped set a record for the most volunteer indexing participants online in a single day, according to FamilySearch’s Facebook page at Over the course of 24 hours, more than 5.7 million records were indexed and 66,511 people volunteered.

Indexing is transcribing information from historical documents to make it searchable online. Once indexed by two volunteers, an arbitrator checks them before the records are live online.

FamilySearch’s previous one-day record was 49,025 individual contributors, set on July 2, 2012.

Since FamilySearch started the indexing program in 2006, more than 1 billion records have been indexed, according to FamilySearch.
