I'm submitting a paper to the journal Elsevier journal "Nonlinear Analysis: Theory, Methods & Applications" (http://www.sciencedirect.com/science/journal/0362546X).
They told me to use the elsearticle document to prepare my submission. The problem is the margins are huge and the line spacing is huge, so my document has doubled in size under this class. So I thought: ok, I need to cut down on my calculations etc. But then I looked at some published articles under that journal, and they do not resemble the elsearticle class at all! The margins are much smaller and the line spacing is much nicer, so much more text fits in.
What is the point of them telling us to use that awful style file? Why should I spend hours reducing my paper when it won't be published in that style and so the changes I make may be entirely unnecessary!
