The technical team at Discovered Money has released a large database of unclaimed property records for the public to view for free. This list is current as of January 26, 2015 and will be updated periodically.
The FDIC (Federal Deposit Insurance Corporation) guarantees many bank accounts a minimum amount if the financial institution holding the funds is closed or fails for any reason. After a bank closure, the FDIC receives a list of depositors from the failed institution and attempts to contact all owners of the funds for transfer to a new institution. Not all of the owners are able to be contacted. This database contains a list of those account holders who are due an unspecified amount of money from the FDIC.
The database is available in Google Sheets at this link.
