changing reference style

Question

I am new to LaTeX and I have received instructions from the journal to change my LaTeX references to conform to

(journal is Cell iScience). whatever I do I cannot fix this issue, please help me.

Answer 1

With biblatex you can build your bibliographic style as you wish.

In the following example I set article and book bibliography drivers as required by the journal you indicated.

The rest of bibentry types (if needed) are left to you.
