Scientific Style and Format presents three systems for referring to references (also known as citations) within the text of a journal article, book, or other scientific publication:

1) citation–sequence

2) name–year

3) citation–name 

These abbreviated references are called in-text references. They refer to a list of references at the end of the document.
