Now that GoldMine has enhanced duplicate checking, those irritating little dupes should not appear too often. However accidents do happen and they are easy to merge together using record tagging. Having spotted a pair of dupes, simply bring up the Contact Listing Window to show the duplicate records. A double click search on the Company name or Postcode should achieve this. Hold down CTRL and click on the first record (the one you would like to keep). Now click on the second (duplicate) record – this should be the one that you want to merge into the first. Go to the Tools Menu, Select Merge/Purge Records and then Merge Tagged Records. The second record tagged will be merged into the first one and you will no longer have a duplicate.
