Among the highlights of the collection is a huge database of British military records, millions of immigration records and passenger manifests for ships sailing to and from Europe, Australia, New Zealand, and the USA, and a vast archive of historical newspapers from around the world including 88 Irish newspapers.
The World collection of some 4billion records will be free to access from Friday 18 September (Noon Dublin/London time; 7am EDT; 9pm AEST) until Monday 21 September (Noon Dublin/London time; 7am EDT; 9am AEST).
If you have a current FindMyPast 'Local' subscription, you'll find your account has been upgraded to give you access to the entire World collection this weekend.
