I am an undergraduate student currently working in a co-op position at a company in my field. I was lucky enough to have the opportunity to be the lead author on a paper based on the research I performed here, and I have a couple of questions regarding what I can do with this information.
I would like to publish it while also making it as visible as possible (partly because I consider myself a proponent of open sharing of information, but also because I'd like to refer future potential employers to it and it would be easier if it were not behind a paywall). I understand that some journals have open access options, but these tend to be quite expensive. What options do I have for publishing in an open way without expensive costs (ideally no cost, since my company has made it clear that they will not financially support publication)?
I understand that one solution to this could be putting it on ArXiv. However, since ArXiv is not a journal, would it be considered incorrect or misleading to call my paper a publication if I were to post it there?
My last question is with regards to contact information in papers. Since I will be leaving the company in a few months, I would like to be able to put an email address in the contact information for the paper that will still be active for a long time. Is it frowned upon or does it look bad if I use my personal Gmail account for contact information?
Thank you for all your help!
