I'd like to learn about the state of the art in network science and which problems researchers are actively working on. In particular, I'm interested in the applications, but the theory is also interesting.
I've found papers on scholar.google.com, and if I'm not mistaken most of the papers are published in application-specific conferences. For example, if network science is used to understand something related to cancer then the results are published in a medical journal. This is making it hard for me to get a consistent view and it's hard for me to get access to such a broad section of the literature (I'm not at a university so I keep hitting paywalls).
tl;dr: Where can I find conferences and journals that focus on network science?
