You can add textbooks for your course as PDF files.
.. note:: Do not use image files (for example, .PNG files) as textbooks for your course, as they are not accessible to screen readers. Review the :ref:`Best Practices for Accessible PDFs` for more information.
Each textbook that you add is displayed to students as a tab in the course navigation bar.
It's recommended that you upload a separate PDF file for each chapter of your textbook.

Image-based Textbooks
=====================
Configuration
-------------
Image-based textbooks are configured at the course level in the XML markup. Here is an example:
Each `textbook` element is displayed on a different tab. The `title` attribute is used as the tab's name, and the `book_url` attribute points to the remote directory that contains the images of the text. Note the trailing slash on the end of the `book_url` attribute.
The images must be stored in the same directory as the `book_url`, with filenames matching `pXXX.png`, where `XXX` is a three-digit number representing the page number (with leading zeroes as necessary). Pages start at `p001.png`.
Each textbook must also have its own table of contents. This is read from the `book_url` location, by appending `toc.xml`. This file contains a `table_of_contents` parent element, with `entry` elements nested below it. Each `entry` has attributes for `name`, `page_label`, and `page`, as well as an optional `chapter` attribute. An arbitrary number of levels of nesting of `entry` elements within other `entry` elements is supported, but you're likely to only want two levels. The `page` represents the actual page to link to, while the `page_label` matches the displayed page number on that page. Here's an example:
It is possible to add links to specific pages in a textbook by using a URL that encodes the index of the textbook and the page number. The URL is of the form `/course/book/${bookindex}/$page}`. If the page is omitted from the URL, the first page is assumed.
You can use a `customtag` to create a template for such links. For example, you can create a `book` template in the `customtag` directory, containing:
.. code-block:: xml
<imgsrc="/static/images/icons/textbook_icon.png"/> More information given in <ahref="/course/book/${book}/${page}">the text</a>.
The course content can then link to page 25 using the `customtag` element:
.. code-block:: xml
<customtagbook="0"page="25"impl="book"/>
