How to Format a Manuscript:

"Briefly, the format of your manuscript must be: 
a. in a word processing format (i.e. MS Word or LaTeX [1]). DO NOT SUBMIT PDF DOCUMENTS (PDF figures are ok).
b. single column
c. double spaced lines
d. line numbers
e. adhere to the reference format standard for the journal
f. figures must be uploaded separately and properly labelled during the submission process.
g. provide a separate list of figure captions and table captions at the end of the text document."

For more on how to format a manuscript for a publishing house see the link titled "Guide for Authors – Computers & Geosciences" as the above information was taken directly from there. There is a lot of useful information there, although it is heavy to read, and therefore maybe a bit dense/complicating to understand or fully comprehend. But I will break it for anyone who asks me to down if need be. However I should note that as it says in the title, this template is geared more towards scientific works. For a sparknotes version that is relevant to novels rather than textbooks or something of the likes, look for the title "How to Format a Novel Manuscript" in my links list. Thanks!

[1] this is my own personal footnote; I should mention that Libre Office is just fine for submitting fiction work; LaTeX is standard for publishing scientific stuff and therefore you don't need to worry about it, CRWR people!
