# Collections and Resources

Collections are project spaces. Each collection keeps notes and resources together so you can move between reading, drafting, and AI help without rebuilding context.

## Hub

The Hub lists your collections. From there you can:

* create a new collection
* search collections by name
* sort by name, item count, or creation date
* open the browser extension setup prompt
* open a collection to work with notes and resources

## Collection tabs

Each collection has two main tabs:

* **Notes:** Drafts, reading notes, outlines, and imported source notes.
* **Resources:** PDFs, Word files, DOI imports, source files, and other project material.

## Adding resources

Use **Add Resource** from the Resources tab to add material in three ways:

* **From Library:** Select existing files from your library, including multiple files at once.
* **Upload New:** Upload a new PDF or DOCX into the collection.
* **Import DOI:** Paste a DOI or DOI URL so Oystack can fetch paper metadata and, when available, an open-access PDF.

If a DOI import does not find an open-access PDF, the item can still appear as a reference-only resource.

## Managing resources

The Resources tab supports:

* searching by title, author, venue, journal, or file name
* filtering by year and resource type
* sorting by date, name, or year
* selecting visible resources
* moving or copying resources to another collection
* removing resources from the current collection

Removing a resource from a collection does not necessarily delete the underlying library file.

## Importing sources into notes

Collections can also turn source files into notes. Use **Import Source** when you want a DOCX, TEX, or ZIP source to become a note, or when you want to append/replace content inside an existing note.

<Tip>
  Keep collections practical. One collection per paper, project, chapter, or
  client deliverable is usually easier to maintain than one large catch-all.
