Web client for Zotero — manage, import, and export your bibliographic references

Quick Start

  1. Open Refero in your browser
  2. Log in via Spectral Cloud Portal
  3. Select a Zotero library (personal or group)
  4. Browse your collections and references
  5. Add, edit, import, or export items

Interface

Refero uses a three-pane layout:

PanelPurpose
Collections (left)Tree view of your Zotero collections with context menus
Items (center)Sortable, searchable list of references in the selected collection
Details (right)View and edit all fields of the selected reference

The interface is fully responsive — on smaller screens the panels adapt to a single-column layout.

Toolbar

The toolbar at the top provides access to:

  • Library selector (personal or group libraries)
  • New item creation
  • Import and export
  • ISBN scanner
  • Settings
  • Language switcher (French / English)

Authentication

Refero connects to Zotero securely through Spectral Cloud:

  1. Log in via the Spectral Cloud Portal
  2. Your Zotero API key is stored encrypted on the server
  3. All requests are proxied through Supabase Edge Functions — your API key is never exposed to the browser

Collections

Collections are displayed as a tree view in the left panel.

  • Create a new collection or sub-collection via the context menu
  • Rename or delete collections from the context menu
  • Navigate by clicking a collection to display its items
  • My Library shows all items across all collections

Working with Items

Browsing

  • Use the search bar to filter items by title, author, or year
  • Click a column header to sort (title, creator, date, item type)
  • Virtual scrolling handles large collections efficiently

Creating Items

Click the + button in the toolbar and choose an item type (book, article, thesis, report, etc.). A new empty item is created in the current collection.

Editing Items

Changes are saved to your Zotero library in real time.
