MyHeritage has added a feature to their record search capability called “Record Detective.” As described by them, when you identify a record of interest in their collection of historical records, Record Detective will provide a summary of additional records in their collection about the person, or about people related to that person. This can be either a bane or a blessing in your research. For the more advanced researcher, the feature would be a disadvantage, because it will make the person aware of records s/he already knows of. For example, locating a person in the 1940 U.S. census might produce a result showing that the person was also found in the 1930 and 1920 censuses. The reaction of the advanced researcher might be that the records are known, yet it might be new information to the beginner.
