a) External links to web pages
b) Internal links within the book
You can add a link to any external website using the VISUAL EDITOR, or the TEXT editor.
Here is how you add a link in the visual editor:
- Write some text
- Highlight the text
- Click on the “Link” icon in the toolbar
- Add your link
Using the TEXT editor, the format should be:
This <a href="http://somesite.com">text has a link</a> and then goes on.
Internal Links (Links Within Your Book)
You can also link within your book, for instance from one chapter to another. The difference when you are linking internally, rather than to a web page as you might be used to, is you don’t have a URL in the traditional sense. Instead, you need to use the identifier (called a slug) of an internal location, of which there can be two kinds: default locations and locations that you create yourself. Both of these are used to indicate an exact point in your document. Here’s how you do it:
Default Internal Links
When you create a document, there are already some identifiers that it will understand. For example, if you want to link to a chapter, you simply need to enter:
To link to a part, enter:
To link to a front matter section, enter:
To link to a back matter section, enter:
The easiest way to find this location identifier is to look at the URL of a page in the web version of your book, if the chapter has been published, and copy everything that comes after .com (including the forward slash).
If the chapter is still in draft, just look at the permalink below the chapter title and copy everything that comes after .com (including the forward slash).
Create Custom Internal Links
In order to create links between more than just chapters or parts, you can create custom location tags that you can then link to from anywhere in your book.
Let’s say you’re writing a section of your book, and want to link to a list of terminology that you have written in an earlier chapter, named “Program Overview”.
- Go to the “Program Overview” chapter
- Find the “Terminology” section heading
- Place your cursor and the start of the heading and click on the “Anchor” button on the toolbar (it looks like a small flag, bottom row, fourth in from the left)
- Enter a name when prompted (this must be unique).
- You now have an anchor tag the start of your heading, and should see it appear as a small icon.
To link to it, go back to your chapter in progress, and follow the instructions above to create a link. When it prompts you to enter a URL, enter:
This indicates that the link is to go to a chapter named “Program Overview” and find the anchor tag called “terminology“.
- Link to figures from main body text and vice versa, eg. See Figure 1 (NOTE: to add an anchor tag to an image caption, you must add it manually in the image editing window, not the visual editor. Simply enter the caption as <a id=”[your-id]”></a>[Your Caption]).
- Link to chapter sub-sections.
- Link to specific sections of back matter.
- Link between chapter sections and their related exercises.
