What is iCloud Shared Photo Library?
Short answer: It's a separate library in Photos that a small group can all add to and edit, alongside each person's personal library. Set it up in Photos → Settings → Shared Library. Deletions apply for everyone.
It's a separate library inside Photos that up to a small group of people can all add to, edit and delete from, alongside each person's own personal library. It's made for families who want one shared collection without merging everyone's accounts.
You set it up in Photos → Settings → Shared Library, choose who to invite and which existing photos to move in. Everyone sees the same shared photos on all their devices. Removing something from the Shared Library removes it for everyone, so agree on house rules. Its storage is covered by one person — see whose storage the Shared Library uses.
