Collections are named lists of articles you put together yourself — “Recipes to Try,” “Trip Planning,” the reading for a course. Open an article, click Add to Collection, and check a collection or type a new name to create one. An article can be in as many collections as you like, and it works for posts from the sites you follow as well as your saved articles. Try it on this article.

Each collection appears in the sidebar like a feed, with its own unread count, so you can read it on its own. Like a feed, you can rename it or give it tags with the pencil icon next to it. An article in a collection isn’t a copy: it stays in its feed or in Saved, and reading or starring it in one place shows everywhere. Removing it from a collection, or deleting the collection, leaves the article where it was — unless you choose to also delete the collection’s saved articles that aren’t in another collection.

Keep Them in Order

A collection can have a reading order. When it does, it opens in that order, and the sort menu above the list switches between that order and date. When you import an ebook, it becomes a collection with an article per chapter, in the book’s order. You can also ask your AI assistant to build a collection for you, or to put one in a sensible reading order.

File Things as You Save Them

When you upload a file, you can pick a collection for it, and when you upload while viewing a collection, it’s picked for you. In the Wallabag app, tags are your collections: tag an article in the app and it’s in that collection in Lion Reader. Your AI assistant can save a link straight into a collection too.
