Use these links to learn more about what you can do with search results in INSPEC & COMPENDEX.
If you have searched both IINSPEC and COMPENDEX concurrently then it's possible that you will have returned duplicate results, i.e. the same records appear in both databases and have both been returned in your results set.
You can remove duplicates by selecting which database's duplicates you want to remove and then click the Remove Duplicates link.
The database automatically removes duplicates in results sets that are smaller than 500.
