Minimal reference content I'm currently preparing a paper for a conference and I'm struggling a bit to stay within the page limit imposed by the Latex layout of this conference. I'm trying to make some extra space for my content without having to use any Latex related tricks (like reducing margin sizes, font sizes, etc...) as this would probably just annoy the reviewers.

Instead, I'm trying to reduce the size of the references by removing unnecessary contents. However, the question is: What is actually unnecessary?

I consider the following to be essential:


Name(s) of the author(s)
Title of publication
Date of publication
Journal or conference of the publication
Page number if the publication was published in a book or proceedings volumes


But what about additional information like DOIs, keywords, abstracts, etc...? Could I safely remove those items to save space?

Thank you very much for your input.
What information is mandatory depends on the applied reference style, e.g. APA6 oder Chicago Style. The reference style even sets the number of authors listed maximum in the reference. Most of the times, the journal/conference sets the reference style you have to apply.

Usually, the mandatory information for journal/conference papers includes:


Author(s) name(s)
Title
Year
Journal/Conference name
Page number
DOI


The only real option to shorten anything is to use the abbreviations of journals/conferences. But the applied reference style might even prevent this trick.
