11 Captions for figures, tables and media

Caption elements

Captions for figures, tables and media include the following elements:

  • They may have a number, as discussed in Chapter 10.
  • They must have a title.
  • They must have an acknowledgement, unless the material was created specifically for the publication.
  • They must have a copyright statement if the content is all rights reserved.

Title and number

  • The title should be short and descriptive.
  • The title should be in sentence case except for proper nouns.
  • For numbered tables or figures, precede title with the word Table or Figure, followed by the number then a colon (e.g. Table 2.4: Population changes).
  • The title and numbering should be bold and italicised.

Acknowledgements

Any figure, table or media which was not created by the author(s) for the book must have an acknowledgement.

The acknowledgement may be:

  • an attribution if the source has a Creative Commons licence
  • a permissions or copyright statement if the source is used with permission
  • a reference for a source that is not Creative Commons licensed but does not require permission (e.g. it is in the public domain or you have had advice from the RMIT Open Publishing Team that you may use the material under existing copyright)
  • an acknowledgement statement for an embedded video which does not have a Creative Commons licence.

See Part III: Acknowledging Sources for details on correctly providing acknowledgement.

If the source has a Creative Commons licence

Use the RMIT Attribution Builder to create an attribution.

  • For tables and figures, add the attribution in parentheses after the title.
  • For embedded videos, add the attribution in parentheses underneath the video.
  • The attribution should be italicised.

See the OER Capability Toolkit for more on giving attribution for Creative Commons licensed sources.[1]

If the source has all rights reserved content

Add a copyright statement.

Note: in Pressbooks when you add an image using the Add Media function, you can create your caption using the dialogue box. Here you will have the option to create an attribution. However, this attribtution will not display in your text.
Instead, after you have added the image, edit the caption in the visual editor to include your attribution or permissions statement.

If the source is used with permission

Add your permission statement in parentheses after your table, figure or media title.

The statement should be italicised.

See Chapter 10: Using Copyright Material and Trademarks With Permission for more on creating a permission statement.

Example

Other copyright material

It is sometimes possible to use material that is under copyright but does not have a Creative Commons licence without permission, as long as the source is properly acknowledged.

Use the footnote function in Pressbooks to add a citation within the text referring to the figure or table, and create a reference according to your referencing style. See Chapter 8: General Guidelines for acknowledging sources.

Contact the RMIT Open Publishing Team for assistance in determining whether you can use copyright resources in your OER.

Adding captions

Images – adding captions using the Add Media function

After you have added an image using the Add Media function in Pressbooks, use the edit-image tool to add a caption.

Edit tool for added image
Accessing the the edit-image tool – use this to add a captions to images.
Tip: The caption will appear below the added image, and be accessible to screen reading software. It will be automatically italicised.

Once you have added the image with its caption, you can edit the caption using the visual editor:

  • Bold the figure number (if there is one) and title. It will be automatically italicised.
  • Add an acknowledgement in brackets.

See Part III Acknowledging Sources for details on when and how to add acknowledgements.

Adding captions manually – tables and videos

If adding a table or video, you will have to manually type in the caption.

In this case, place the title above the table or video, and place the acknowledgement below.

Tip: It is necessary to place the title above for accessibility reasons so that screen readers read out the title before they pass onto the table or video underneath it.

Example
