Searching the Inspec Classification Index

This search aid allows you to select one or more classification codes to add to your search query. Only the top levels of the hierarchy are shown when initially accessing the Inspec Classification search aid, and includes:

• Physics 
• Electrical Engineering &amp Electronics
• Computers & Control
• Information Technology
• Manufacturing & Production Engineering

The product automatically finds records for all classification levels under a second, third, and fourth level classification code. For example, adding the second level code C3000 Control Technology, the product finds records indexed with C3000, C3100, C3200, and C3300 classification codes, including codes that are under them in the hierarchy. You do not have to add all the codes if you select C3000 at the second level.

See Inspec Classification Details for more information about classification codes.
