Welcome to Wikipedia. Here are suggested readings: WP:SECONDARY and WP:COI. The gist of these guidelines are:

• Wikipedia prefers citations to reviews and books, not primary journal references (tens of thousands appear annually). Citing secondary sources is the encyclopedic style.
• Do not cite yourself or your colleagues. It's called conflict of interest. Many new editors cite themselves mainly. That behavior is inappropriate.

If you have questions, many editors can offer advice. Happy editing.--Smokefoot (talk) 12:05, 5 January 2019 (UTC)[reply]

Hi,

Thank you for the reminder. After consideration of the possible conflict of interest, I think its more appropriate if I removed the section/reference I added.
