From: How to Write and Illustrate a Scientific Paper (2008)
The title will be read by many people. Only a few will read the entire paper, therefore all words in the title should be chosen with care. Too short a title is not helpful to the potential reader. However too long a title can sometimes be even less meaningful. Remember a title is not an abstract. Also a title is not a sentence.
• Fewest possible words that describe the contents of the paper.
• Avoid waste words like "Studies on", or "Investigations on"
• Use specific terms rather than general
• Watch your word order and syntax
• Avoid abbreviations and jargon
The title should be clear and informative, and should reflect the aim and approach of the work.
The title should be as specific as possible while still describing the full range of the work. Does the title, seen in isolation, give a full yet concise and specific indication of the work reported?
Do not mention results or conclusions in the title.
Avoid: overly clever or punny titles that will not fare well with search engines or international audiences; titles that are too short to be descriptive or too long to be read; jargon, acronyms, or trademarked terms.
