I am currently building a reading list targeted towards a certain list of 5-10 authors. They all work under the umbrella of wireless communications (separated by their own subfields), and I would like to efficiently go through their recent works. To facilitate the search, I would like to know their "affinity" towards each other via co-authorship links. I am hoping this might shed light into the development of their ideas.
My question is: is there a resource for finding (possibly indirect) connections between authors?
The best I could find is DBLP but this only gives the list of authors who are direct co-authors. Also, this link suggests Visual Explorer from Microsoft Academic, but it seems to be no longer available.
