Microsoft Word allows adding footnotes and endnotes easily. These usually appear at the bottom of a page (footnotes) or at the end of the document (endnotes), with a reference number linking them to a specific location in the main text.

To do so, follow the instructions on the section “Adding a Footer to Multiple Slides”.Many books and academic papers require citing of references, giving explanations, and making comments. If you want a footer for all the slides except the cover slide, you’ll have to add a footer to all the layout masters instead. The footer will appear on all the slides of your presentation, including the cover slide. Exit the master editor view by clicking the “X” button at the top-right.You can modify the font, the size, the style and the color of the text by using the options found on the toolbar.To do so, just click and drag until you’re happy with the size of the box.

Draw a text box where you want to place the footer.Select the slide master (the first one, which acts as the parent slide).Open your presentation in Google Slides.The footer will appear on all the slides derived from this layout master. You can modify the font, the size, the alignment, the style and the color of the text by using the options found on the toolbar.Now draw a text box where you want to place the footer.On the toolbar, click the Insert placeholder drop-down arrow and select Text box.By default, the layout master from which your chosen slide derives will be selected. Access the master slides by clicking Slide → Edit master.Select the slide where you want to add the footer.

As long as they derive from the same layout master, you can do it easily. You can save some time if you have several slides with a similar layout and want to add a footer to all of them.
