Is there any standard style for adding author information in research papers? I see different papers use different styles. Some have affiliation and contact address only. Some have affiliation, email, contact address in full. Some include designation also. So what is the best style one should follow? I am preparing a paper for a Springer Conference.
I think you should keep in mind how people are going to use this information and for what purpose.
You use it to advertise yourself and your identity. You hope that little by little, people learn to recognise your name and know what kind of work you do.
Other researchers will use the information to find more information about you and your work. If they find a relevant paper written by you, they might want to find your home page and see if you have done more recent research on the same topic. Or they might want to contact you and ask more about your work.
Various organisations will use it to construct bibliography databases (DBLP, ACM Portal, MathSciNet, etc.) and to come up with all kinds of statistics (how many papers were published by university X). The editors of the bibliography databases typically want to figure out which papers are written by the same person (far from trivial, as the names are not unique).
Some advice based on the above use cases:
Please try to include your full name. Do not abbreviate your first name. Use the same version of your name in all research papers, and use the same version on your home page. For example, if you decide to use middle initials, do it consistently.
An email address might be a good idea (at least if you are not worried about spam email). Not that I would ever send email blindly to an address that I see in a paper, but googling for the email address might be much faster than googling for your name if you happen to have lots of namesakes.
Affiliations (the names of the universities, departments, institutes, and/or companies) are a must to keep your employers happy... They also help with disambiguation if you happen to have lots of namesakes. (Unfortunately people change universities often or have double-affiliations, and this will also create some confusion in the bibliography databases.)
I have no idea who would ever use your full postal address for anything nowadays – if they need it, they can google for up-to-date information. However, it might be nice to include the town and country, especially if your university does not happen to be named after (a well-known) city.
