I'd like to studying knowledge production patterns in the field of Health Communication by using bibliometric approach. My first step is to collect information of literatures. Here I want to collect all the literatures of the two most important jouranls (Health Communication, Journal of Health Communication) in this field. Then I search the rest literatures of other jouranls from Web of SCI core collection by subject"health communication". Is my way of collecting data feasible? or any other suggestion?
