I am a physics student and as far as I know dark matter is beyond the topics included in my grade career. Are there any serious book on the subject? Any serious set of lectures somewhere in Internet?
There is an excellent book by Iain Nicolson called "Dark Side Of The Universe" which covers this in great detail. I recommend it for the following reasons:
1) it furnishes a thorough historical overview of the problem, going back to the earliest work by Zwicky
2) it contains a detailed description of all the observational and instrumentation techniques used over the years by the astrophysics community to infer its presence and map its distribution
3) it provides an exhaustive list of all the potential candidates for dark matter particles and a discussion of why or why not they are viable
4) it ties the topic together with an equally thorough discussion of dark energy
5) it explains the connection between dark matter, dark energy and cosmology
6) it is accessible by nonspecialists
