Why Use Notero?

• Integrate your reference manager, task list, reading notes, analytical tables, and drafts in one location.
• Easily link to references when writing in Notion.
• Create custom views to filter and sort large reference lists by project, tag, author, etc.
• Backlinks make it easy to locate any of the notes and drafts that mention a reference.
• Link references to entries in other databases, such as projects, tasks, manuscripts in your publication pipeline, publishing outlets, etc.

How Notero Works

The Notero plugin watches for Zotero items being added to or modified within any collections that you specify in the Notero preferences. Whenever an item is added or modified, Notero does a few things:

• Save a page with the Zotero item's properties (title, authors, etc.) into the Notion database specified in Notero preferences.
• Add a notion tag to the Zotero item.
• Add an attachment to the Zotero item that links to the page in Notion.

In addition to providing a convenient way to open a Notion page from Zotero, the link attachment also serves as a reference for Notero so that it can update the corresponding Notion page for a given Zotero item.

Syncing Items

By default, Notero will sync items in your monitored collections whenever they are modified. You can disable this functionality by unchecking the Sync when items are modified option in the Notero preferences.

You can also sync items from the collection or item context menus (right-click):

• To sync all items in a collection, open the context menu for the collection and select Sync Items to Notion.
• To sync one item or multiple items, select the item(s) in the main pane, open the context menu, and select Sync to Notion.

[!NOTE] To prevent the "sync on modify" functionality from saving to Notion multiple times, Notero does not notify Zotero when the tag and link attachment are added to an item. This means they may not appear in Zotero immediately, and you may need to navigate to a different item and back to make them appear.

Syncing Notes and PDF Annotations

Zotero notes associated with an item can be synced into Notion as content of the corresponding page for that item. As with regular items, you can manually sync notes using the Sync to Notion option in the context menu.

Automatic syncing of notes can be enabled via the Sync notes option in the Notero preferences. When enabled, notes will automatically sync whenever they are modified. Additionally, when a regular item is synced, all of its notes will also sync if they have not already.

To sync annotations (notes and highlights) from a PDF, you'll first need to extract them into a Zotero note:

1. Select an item or PDF, open the context menu, and select Add Note from Annotations.
2. If desired, enable highlight colors from the menu at the top-right of the note panel.

Example of creating a note from PDF annotations

Installation and Setup

Using Notero involves installing the plugin in Zotero and connecting it to a Notion database. Detailed setup instructions are below.

Install and Configure Notero Plugin

[!IMPORTANT]

• The latest release of Notero requires Zotero 10 or above.
• Support for Zotero 7, 8, and 9 is available in Notero v1.2.3.
• See the changelog for all release notes.

1. Download the latest release of the .xpi file.
   • Alternatively, download the .xpi file from the Assets section of the latest release page.
   • Firefox users: Right-click the download link and choose Save Link As... to download the file.
2. Open the Zotero Plugins Manager via the Tools → Plugins menu item.
3. Install the .xpi file by either:
   • dragging and dropping it into the Plugins Manager window or
   • selecting it using the Install Plugin From File... option in the gear menu in the top-right corner of the window
4. Open the Notero preferences from either the Tools → Notero Preferences... menu item or the sidebar in the main Zotero preferences window.
5. Configure the Notero preferences as desired.

Connect to Notion

[!NOTE]

Before version 1.0.0, Notero required you to create your own Notion internal integration and manually set the integration secret in the Notero preferences. This is no longer necessary as Notero now uses a public integration with an authentication flow provided by Notion.

If you previously set up Notero with an internal integration, you can click the Upgrade Connection button in the Notero preferences to switch to the public integration as described below. Once complete, you can delete your internal integration from the Notion integrations page.

1. Start the Notion connection process by clicking the Connect to Notion button in the Notero preferences. This will open the Notion connection page in your default web browser.
2. On the Notion connection page, select your desired workspace from the menu at the top (if you have multiple). Then, click Next.
3. On the next page, choose whether you want to use a template database or connect to an existing database page.
   • If you choose to use a template, the basic example database will be duplicated into your workspace.
   • If you choose to select an existing database, you can search for and select your preferred database on the next page. You can also select no database and connect one later in Notion.
4. Click Allow access to give Notero access to your Notion workspace and database. You will then be redirected to a page that prompts you to open Zotero.
5. Click Open Zotero to complete the connection process in Zotero. The Notero preferences should show that you are connected to your Notion workspace.
   • If Zotero does not open or successfully connect to Notion, copy the connection token from the Notion connection page and paste it into the Connection Token field in Notero preferences.

Example of connecting to Notion

Configure Notion Database

If you choose not to use the template database during the Notion connection process, you will need to create your own database. See examples below that you can duplicate into your workspace, or create one from scratch with properties described in the database properties section below.

To give Notero access to your database, follow these steps:

1. Go to the database page in your workspace.
2. Click on the ••• More menu in the top-right corner of the page.
3. Scroll down to and click Connections.
4. Search for and select Notero in the Search for connections... menu.

Example of connecting database to Notero

Notion Database Properties

Notero can sync data for the properties listed below. The only property required by Notero is one with the Title property type. The other properties are optional, so you can use only the ones that suit your needs.

The Title property can be named something other than Name as long as it does not conflict with any of the other property names. The name and type of the other properties must be configured exactly as specified here. Note that property names are case-sensitive, so the capitalization must match exactly.

Support for customizing properties is planned for the future; see issue #355.

Frequently Asked Questions

How to sync from Notion back into Zotero

Bidirectional sync between Notion and Zotero, while desirable, falls outside the scope of this plugin. Implementing this functionality would require developing a separate hosted service that could both listen for Notion webhooks and interact with the Zotero API to propagate changes. While technically feasible as a standalone project, this capability is not part of Notero's functionality.

How to sync attached files into Notion

There currently isn't a good way to sync files or link to local files due to the following limitations with Notion:

• The Notion API does not currently support uploading files.
• Notion only supports http: and https: URLs, so it's not possible to link directly to the file using a file: URL.

For now, the best workarounds are:

• Use the File Path property to point you to the location of the local file.
• If you sync your files into your Zotero account, you can open the Zotero web interface from the Zotero URI property and then open the file from there.

How to bulk sync existing items

To sync multiple items that are already in a monitored collection, you can do so from the collection or item context menus. See the Syncing Items section above.

How to fix Notion API errors

Could not find database

If you receive the following error:

APIResponseError: Could not find database with ID: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

This most likely means you have not given Notero access to your Notion database. Ensure you follow the steps in the Configure Notion Database section. Clicking the ••• button in the top-right corner of your database should show a connection for the Notero integration.

Can't update a page that is archived

If you receive the following error:

APIResponseError: Can't update a page that is archived. You must unarchive the page before updating.

This can happen when Notero tries to sync an item that already had a Notion page created for it from a previous sync, but that page has since been deleted. (Note that deleting a Notion page moves it into the trash, and the Notion API refers to this as "archived.")

As described in the How Notero Works section, Notero associates Zotero items with Notion pages through a link named Notion attached to the item. To resolve the issue, delete this link attachment on the offending item(s) and then perform the sync again.

Not a property that exists

If you receive the following error:

APIResponseError: property is not a property that exists

This can happen if you previously synced items into one Notion database and then change your Notero preferences to specify a different database. Notero may be trying to update pages in the old database instead of creating pages in the new database, and this error can occur if different properties were configured in the different databases.

To solve this, you should delete the old database in Notion and then permanently delete it from the Trash in Notion.

Example Notion Databases

We provide some example Notion databases that have been configured with all the properties synced by Notero.

Once you've opened one of the examples, click the Duplicate button in the top-right corner of the page to duplicate it into your Notion workspace.

Basic Example

An empty database that contains only the properties synced by Notero. Useful if you want to start from scratch and customize it yourself.

Advanced Example

A database with multiple views and some sample entries. See below for descriptions of how you can use the different views.

Bibliographic Info Table View

• Table view enables easy editing of entries.
• Easily navigate to the original source by clicking on the DOI or URL property.
  • DOIs for books may need to be copy & pasted manually from the Extra field in Zotero.
• Click on the Zotero URI property to view/edit the entry in Zotero or to export the bibliography entry in a different citation style.

Reading Status Board View

• Keep track of promising references you need to locate, books and articles you requested via interlibrary loan, and works that are relevant enough to warrant taking in-depth notes or writing a memo.

Literature Review Table View

• Quickly analyze and compare attributes of literature you are reviewing (e.g., theoretical framework, sample, methods used, key findings, etc.)
• Easily link to other works using the Related References property (e.g., articles in the same special issue, book chapters in the same edited book, studies and commentary that respond to or extend other works).

Books Gallery View

• Add a cover image (e.g., right click → copy image address from Amazon).
• Keep track of which books you own, borrow, and lend to others.
  • Add due dates and reminders for library books and interlibrary loans.

Development

Notero was scaffolded with generator-zotero-plugin and uses build scripts heavily inspired by zotero-plugin. Many thanks to @retorquere for creating these.

Local Setup

Notero uses Vite+, a unified toolchain for dependency management, linting, formatting, testing, and task orchestration. The plugin build still runs through the project's existing esbuild scripts. You'll need to install the vp CLI before getting started. See the Vite+ website for installation instructions.

The steps below are based on the Zotero Plugin Development documentation and should allow you to build and run Notero yourself.

1. To avoid any potential damage to your default Zotero profile, you can create a new profile for development purposes.

2. Create a file named zotero.config.json that will contain the config options used to start Zotero. See zotero.config.example.json for an example file that has descriptions of all available config options.

3. Install dependencies:

   vp install
   

4. Build Notero and start Zotero with the plugin installed:

   vp run start
   

   Alternatively, you can start your desired beta or dev version of Zotero:

   vp run start:beta
   vp run start:dev
   

   The start script performs a number of steps:

   1. Run scripts/build.mts to build the plugin into the build directory and watch for changes, rebuilding when necessary.
   2. Use web-ext to start Zotero with the profile specified in zotero.config.json and install the plugin as temporary, reloading when the plugin is rebuilt.
   3. Write Zotero debug output to the logFile if specified in zotero.config.json.

Releasing a New Version

Releases are performed via GitHub Actions. The release workflow defines the following jobs:

release-please

This job uses the release-please action to create release PRs when new user-facing commits are pushed to the main branch. A release PR will bump the package version and update the changelog. When the PR is merged, this job then creates a new version tag and GitHub release.

publish-artifacts

This job runs when a new release is created by the release-please job. It builds the .xpi file and publishes it to the release. It also generates an updated manifest file and publishes it to the release release.
