Accessibility

Accessibility Thorium Reader is for everyone, including people who are blind or have other types of visual, cognitive or motor disabilities. The application is compatible with accessible technologies like screen readers, including JAWS, NVDA, Narrator and VoiceOver. It includes a read-aloud feature with visual highlighting. Thorium Reader can be used with the mouse or the keyboard, and keyboard shortcuts are configurable. The display can be customized to meet the needs of users, including colors, text size, spacing, font and layout.

Reading with a screen reader

Reading with a screen reader When launching Thorium, if a screen reader is detected, the relative functions are activated. Note that screen readers use a separate buffer to access the HTML content which results in the visual scroll / page offset to be out of sync. In other words, Thorium is generally not aware of the user's current reading location inside the screen reader buffer, unless the screen reader user triggers standard web API events (such as mouse click anywhere in the text, or keyboard tab into focusable HTML elements).

Minimum system requirements

Platform support is provided by Electron as defined in Electron github repo Readme Each Electron release provides binaries for macOS, Windows, and Linux. macOS (Big Sur and up): Electron provides 64-bit Intel and Apple Silicon / ARM binaries for macOS. Windows (Windows 10 and up): Electron provides ia32 (x86), x64 (amd64), and arm64 binaries for Windows. Windows on ARM support was added in Electron 5.0.8. Support for Windows 7, 8 and 8.

Frequently asked questions

Why can't I open an ebook without it being save in the Thorium Reader library? Thorium, like several other ebook readers and reading systems stores imported publications in its own filesystem space, as this provides a guarantee that per-publication state and external metadata (e.g. bookmarks, settings, annotations, DRM status, etc.) can be reliably attached. If you need to open files without using advanced reading features, and want to keep a manual maintenance of ebook files, you can consider using an alternative.

Stuck?

If you do not find the answer to your problem on this site, you can tell us your problem via our support tracking tool or contact form. Here is the information we need: Operating system and it version Thorium version (it is indicated at the bottom of the library under the title About Thorium)

EPUB

(Electronic PUBlication) is an open file format for electronic publications. EPUB is a native semantic format allowing to use numerous standardised languages such as HTML, ARIA, MATHML, SVG and others. The actual version 3 is known to provide the best up to date reading experience. Obsolete EPUB2 files are also readable in Thorium.

DAISY

Usually produced and distributed by specialized libraries or NGOs, the DAISY format offers a significantly enhanced reading experience for ebooks that are not available in EPUB3. Thorium supports reading DAISY 3 and 2.02, both in their text only, audio only, and syncronised text and audio.

PDF

despite a well-known lack of flexibility (no reflow option) and accessibility, many ebooks are still available in PDF only, especially in public libraries.

Audiobooks

a standardized format for audiobooks has been designed by the W3C Publishing Working Group in 2020, and EDRLab was part of this WG. Thorium is supporting the packaged (LPF) audiobook format, which will soon be widely used by booksellers, or so we hope.

Visual narratives

EDRLab has designed a standard format for comics, manga, webtoons and other styles of digital works based on sequances of images. Divina is the name of this format. This is still an experimental format, and we hope that publishers will size it in 2021+.

3.8 - Frequently asked questions

Why can't I open an ebook without it being save in the Thorium Reader library?

Thorium, like several other ebook readers and reading systems stores imported publications in its own filesystem space, as this provides a guarantee that per-publication state and external metadata (e.g. bookmarks, settings, annotations, DRM status, etc.) can be reliably attached.

If you need to open files without using advanced reading features, and want to keep a manual maintenance of ebook files, you can consider using an alternative. A possibility is the Readium2 “test app”, a basic reader-only app (i.e. no library / bookshelf) which provides rudimentary support for ebook features (bookmarks, highlights), with a crude user interface designed for testing the SDK. You may give it a try using the automated builds from Readium2 “test app”GitHub’s releases page

Adding a "one shot reading" feature is not on our road map. Neither is the maintenance of a public stable web reader.

Why is there no read aloud nor annotations for PDFs?

EDRLab considers that EPUB 3 is a far better ebook format than PDF, and therefore prioritises its work on offering a great experience to EPUB users. In Thorium Reader, advanced features like TTS and annotations are consequently available for EPUB first, and we expect that other app developers will get the best from PDF files. It does not mean that advanced features will never be available on PDF in Thorium, simply that our limited budget is used for what we consider best for ebook readers.

I can't select the adequate voice for read aloud function (TTS)

Thorium uses the voices from the computer's operating system, in combination with the language information provided by the book.

• If you are using windows you can follow Microsoft’s guide Download the language pack for voice.
• If you are using Mac OSX the guide Change the voice that the Mac uses to pronounce text.

Once the required voice is installed, Thorium will choose the voice corresponding to the language of the book.

It may happen that the book has the wrong language. In this case, Thorium allows you to change the voice to one that is present in the system via the Voice menu

How can I transfer the entire book collection from one machine to another?

Having a UI for exporting the whole catalog is not a priority currently.

The publications are stored in a well-known directory.

• on Windows10: C:\Users\myname\AppData\Roaming\EDRLab.ThoriumReader\publications\
• on MacOS: /Users/myname/Library/Application Support/EDRLab.ThoriumReader/

In case of a migration from one computer to another or similar usecases, you can copy all ebook files in this repository and open them in the new installation of Thorium.

opds.informations	Imagine a world where you can explore and download digital publications from public libraries and digital booksellers with just a few clicks. That’s exactly what the Open Publication Distribution System (OPDS) catalog format offers. With OPDS, you can navigate through catalogs from various ebook providers, sign up, borrow, buy a publication, or visit your personal bookshelf. You can even download an ebook or audiobook directly into Thorium Reader for instant reading.	So, how do you find an OPDS catalog? It’s simple. Look for a hyperlink (URL) leading to the catalog. Copy this URL into the Link field above. Keep in mind that there’s no one-stop shop for all active OPDS catalogs. You’ll need to contact your preferred library or bookseller and ask for their OPDS catalog URL. If you’re not sure where to start, Wikipedia has a few registries of OPDS catalogs in various languages that might be helpful.	The Name field is left at your convenience; it provides an easy way to identify the feed in Thorium Reader.

4.4 - Your help is precious

You too can help Thorium Reader become the best reading application reading application by becoming a member of EDRLab. Or by making a donation to the EDRLab via the Github sponsorship "piggy-bank", which accepts small monthly donations.

Thorium is built by its community. If you want to participate, please contact us !

You can also:

• Report an error or suggest a change by opening an Issue in our [support tracking tool](https://github.com/edrlab/thorium-reader-doc/issues/new).
• Participate in the translation of resources.

4.5 - Contribute to this documentation

Thorium and its documentation are developed thanks to the user community. We need help to translate this documentation.

To do so, you can contact us.

If you are comfortable enough with GitHub and the Markdown format you can propose a new translation via a Pull Request.

To do this: clone the repository and create a branch with the name of the language you want to add, make a copy of the content.en folder and rename it with two letters corresponding to the language you want to add (for example content.es will contain the Spanish translation). The names of the files must not be changed as they insure correspondence between languages.

The i18n folder contains the translations for the fixed elements of the header and footer. Several languages are already present, if your language is not present, copy paste the .yaml file and rename it with the first two letters of the letters of the language you want to add.

Finally to activate the menu of the language you add, edit the file config.toml and add the language with the following code:

[languages.en]
  languageName = 'English'
  contentDir = 'content.en'
  weight = 1

You must replace .en' with the first two letters of the language you are adding and fill in the name of the language as the languageNamevalue. Theweight` indicates the order of appearance in the language menu.

Example for Spanish :

[languages.es]
  languageName = 'Español'
  contentDir = 'content.es'
  weight = 3

Localized images such as screenshots should be added to the folder statics/images/local-(two letter language).

5.3 - Privacy Policy

22 November 2022

Owner of the application

European Digital Reading Lab 14 rue Alexandre Parodi 75010 Paris France

Types of data collected

The application does not collect Personal Data from its users.

The application sends two kinds of non-personal data to servers:

1/ Generic usage data: a notification is sent to an EDRLab telemery server each time the application is started. This information is for analytics only and not accessed by any third party. It is used to get information about the evolution of the number of installs of the application per operating system, the evolution of usage sessions and the main locales in use.

Parameters of such notification are:

• a timestamp,
• the version of Thorium Reader,
• the operating system of the device and its version,
• the locale of the application at the time it is started,
• if this is the first start of Thorium Reader after a fresh install.

The IP address of the device is not stored along with the above information.

It is not possible to opt-out from this notification.

2/ Readium LCP DRM information: a notification is sent to an LCP Server each time a protected publication is open. This is required by the LCP specification for checking if the license of use of the publication has been updated. There is not centralized LCP Server, each server is operated by the distributor of the protected publication acquired by the user.

Parameters of such notification are:

• a device identifier, automatically generated at the install of the application.
• a device name, automatically generated at the install of the application.

The codebase of Thorium Reader is open-sourced and can therefore be fully inspected, with the exception of a small software library used as core for the Readium LCP DRM, which does not store or send any data.

Updates

We may change the Privacy Policy from time to time. We will notify you by posting the revised Privacy Policy on this page and the date on which the last changes were made will be noted at the top of the page.

5.4 - Accessibility policy

EDRLab is a non profit developpement laboratory and places accessibility as a core requirement of it’s actions. That include the developpement of Thorium Reader.

However, the core aspect of innovation and experimentation of our work may affect accessibility at some points. Funding limitations may also affect our action and will to provide the best reading experience for all readers. These are the main reasons why we cannot, at this moment, afford a full accessibility testing cycle at each release.

Any identified blockers are publicly informed and searchable via a dedicated Label Accessibility on our Issue tracker that are treated as priority by the development team.

## understanding all and each users’ needs

We capture feedback about customers’ experiences from an accessibility perspective thru different channels: * Developpement Issue tracker dedicated Label Accessibility * Email contact form * Indivdual feedback collected by our members organisations dedicated to serving people with disabilities

## Thorium Reader accessibility features are informed

When an accessibility feature is introduced, we make that information public thru

• the version change log
• a short mention on the website landing page
• listed for reference in this website ressources section, accessibility page
• all accessibility related explanations are available in the documentation, not in a separate chapter or place.

Support for assistive technology

A specific attention is given to non visual access thru screen readers.

As much as possible we intend to maintain a similar access path between visual and non visual access. Whenever necessary, we use dedicated technologies like ARIA-Role.

New functionalities are tested with screen readers.

Accessibility testing

* Community testing thru [epubtest.org](https://epubtest.org/)
