Indent second (and potentially third) line for references: style?

I want to use or create a style that conforms to scholarly textbook references sections where the second line (and potentially third) is indented slightly from the normally placed first line of each of the references.

I’ve searched and searched but can not connect with any solution.

The “first line indent” is relative to the “before text indent.”

“Before text” set the space from the left margin(1) while the “first line indent” determines where to put the first line in reference to the “before text” setting. That is, if we define the “before text” indent as 1 cm and a first line indent of 0.5 cm, this first line will be found at (1 + 0.5) cm = 1.5 cm from the effective edge of the text area.

On the other hand, if we define a “before the text” indent as 1 cm and a first line indent of –0.5 cm, the first line will be (1 − 0.5) cm = 0.5 cm from the effective edge of the text area.


(1) Actually, because you can have a “space to content” from the margin, that’s not completely true, but anyway.

This is confusing. Could you, please, explain it straight forward_
How to indent second line and the rest in a paragraph?

I figured it out:

For example:
Using the “Endnote” style, in “Indents & Spacing” I changed the “Before Text” default from 0.00" to 0.25" and the “First Line” to -0.25"

Works, but I don’t understand the logic of adding a value to “Before Text” when I don’t actually want it to change…and it doesn’t change if I set “First Line” to negative: -0.25"

So, what does it mean to set a value for “Before Text” when it actually doesn’t change? Something is default relative to something…???
