Content in the BOMA content library can be shared via social media, email and as a blog on your website.
The only time you need to attribute the original source of the content is if you are using a BOMA article on your blog.
If the article you choose has a call-to-action that takes you to a separate website (e.g. Xero's Small Business Guides) then you should attribute that as the original source.
Here's 2 examples of how you might cite the source or correctly attribute an article:
