These are the TOP 3 resources I encountered in 5 years to help with the writing of a journal article:
- template with advice/tips/structure for journal article writing, at this website
- Writing for Academic Journals, 2nd ed., by Rowena Murray
- Writing Your Journal Article in Twelve Weeks: A Guide to Academic Publishing Success, by Wendy Laura Belcher. NOTE: This source is good for turning theses or conference papers or the like into journal articles.
