Artist directories, collective indexes, shared archives, interconnected artist websites, resource hubs, and mutual linking structures can all support discoverability without treating visibility as a campaign.
These forms are most useful when they preserve continuity: a way to find an artist after a platform changes, a way to understand who worked together, a way to keep a local or dispersed community from becoming invisible in scattered feeds.
A directory does not need to speak for everyone it lists. It can be a careful table of contents, an outward-facing record, or a set of paths back to artists' own websites and archives.
