Reference List: 

The general format for referencing journal articles  

Author, A. A., Author, B. B., & Author, C. C. (Year). Title of article. Title of Journal, volume number (issue number), page range. https://doi.org/xx.xxx/yyyy 

The general format for referencing electronic sources/weblinks 

If you are citing a web page with an individual author: 

Lastname, F. M. (Year, Month Date). Title of page. Site name. URL 

If the web page belongs to an organization or group rather than an individual: 

Group name. (Year, Month Date). Title of page. Site name. URL 

If there is no date, just use (n.d.) to indicate that. The only other major thing is, if you are citing a web page that is likely to change over time (like a wiki), include a retrieved date. 

Title of page. (Year, Month Date). Site name. Retrieved Month Date, Year, from URL
