What are supplemental sections?
The supplemental sections address more specialized project requirements. These sections are not part of the basic package but are part of the expanded package. Not all libraries have an expanded package. If you have a basic package license, you may order individual (supplemental) sections from the supplemental version at discounted prices. You do not need to upgrade your license to the expanded package unless you would need to add multiple supplemental sections. If this is the case, then it might be more economical to upgrade your license to the expanded package. Compare libraries, section types, and quantities.
