A grantor–grantee index is a general term for two lists of real property transfers maintained in alphabetical order of the last name of the parties transferring the property.
Transfers are not necessarily listed in strict alphabetical order, but are often placed chronologically in a letter index corresponding to the first letter of the party's last name.
In each entry, the name of the grantee (purchaser) is then given, along with the location of the affected parcel and the volume and page number where the full text of the deed or other recorded instrument describing the transfer may be found.
In the grantee index, the order of entries is by the grantees' last names, and each entry provides the same identifying information for the recorded instrument.
More recently, in many United States offices, the records have been stored on microform or on computer.
