I have seen the other questions regarding which publication date to use, and it seems clear to use what the publisher uses. But what if the publisher provides several dates such as the following?
- Issue online: 25 January 2016
- Version of record online: 25 October 2015
- Accepted manuscript online: 7 October 2015
I find these definitions confusing. Which data should be used as the official publication year? What does version of record online even mean; is it important?
