When to use
Your library may publish frequently updated web content such as news and/or blog and you may want the latest updates automatically added to your website.
If you want to display a list of latest posts in the sidebar on all pages of your website, use the WordPress built-in RSS widget. You can add it by going to Appearance -> Widget -> RSS. Please note: only a site administrator can create a site-wide RSS widget.
If you want to display the title of the latest post on a specific page, use this shortcode.
If you want to display the name of the author, set the value of the author attribute to 1.
The text attribute inserts whatever text/label you want to added before the post title and separate them by a colon and a space.
The two attributes can be used at the same time.
