# Library of negative keywords
The library of negative keywords is a folder where you can group frequently used negative keywords into special sets. You can create up to 30 sets and use them in multiple ad groups or campaigns at once. You can add sets of negative keywords in the unified performance campaign. Up to three sets of negative keywords can be assigned to one group. Library sets supplement the negative keywords specified in the group and affect ad impressions the same way.
