Who will Write?
When there are multiple authors, one
only must write the paper.
Too many writers produce a
patchwork of different styles.
Who will Write?
Authorship, like so many acquired
skills, must start early in life.
Junior should write.
Senior should revise.
Sequence of Writing
First version
Write the paper in the following sequence:
1- Materials and methods.
2- Results (provisional tables, illustrations
and figures).
3- Discussion.
4- Introduction
Write the maximum information you have.
Sequence of Writing
Fourth version
1- Finalize the references.
2- Write the abstract and summary.
