The Inspec database (Engineering Village platform, 1896 to present) is available to only Georgia Tech registered users.
Search both the Inspec database and the Compendex database together; check both boxes under Databases. These two databases are complementary and only have about a 20 percent overlap. Duplicate records can be removed by clicking of "Remove Duplicates" (left column) and "Database Preference"
The NTIS technical report database and the pulp and paper technology Paperchem database are also Engineering Village databases.
