Yes, you can add content from your own blog to your library. You can do this in two possible way:
You can import such content – if it’s a single content – through the “IMPORT URL” feature available under “Import Content” in your library. You need a direct link to the article to do this.
You can also import multiple content from your blog provided that your blog has an RSS Feed of XML format. This method can be done using the “IMPORT RSS” option/feature under “Import Content” in your library.
