# Influencer Library Attrisys provides access to influencers from YouTube, Instagram, and TikTok. You can easily search for influencers directly from the Library page using keywords, or filter by location, follower count, engagement rate, and other dimensions.

The library displays key metrics for each influencer, such as follower count, engagement rate, view rate, and their latest posts or videos.

If you find an influencer of interest, you can add them to your [collections](/documentation/how-to-run-influencer-marketing-campaigns/collections.md) or a custom list.

If you have an existing partnership with an influencer, you can quickly add them to your influencer marketing campaigns via a shortcut (See: [How to run influencer marketing](/documentation/how-to-run-influencer-marketing-campaigns.md)).

If you don't find the specific influencer you are looking for, you can also manually add them.

Attrisys supports both individual additions and bulk uploads from a local file.
