Final answer:
To remove extra space on the right side in Word, select the text, go to 'Paragraph' settings within the 'Layout' tab, and set the 'Right' indentation to '0'. Use 'Hanging' indent to format bibliographies correctly.
Step-by-step explanation:
To remove extra space on the right side in Word, begin by clicking on the text you wish to edit. If you want to remove the extra space from the entire document, you can use the shortcut 'Ctrl+A' to select all text. Then go to the 'Home' tab and look for the 'Paragraph' group. Here, you'll find an icon for 'Line and Paragraph Spacing.' Click on this and make sure that the extra spaces option is turned off. To adjust indentation, go to the 'Layout' or 'Page Layout' tab, locate the 'Paragraph' section, and click on the small arrow in the corner to open up the 'Paragraph' settings dialog box.
In the Paragraph dialog box, you'll see 'Indentation' options. Typically, extra space is due to the 'Right' indentation being set to a value higher than needed. Set the 'Right' indentation to '0' if you want to remove extra space on the right side completely. If you are setting up a bibliography and need hanging indents, start each entry at the left margin and indent subsequent lines one-half inch; in Word, you can do this by selecting 'Hanging' from the 'Special' options in the 'Indentation' section.
