The variety of philosophical and applied phenomenological literature is a rich source for insights.
It speaks for itself that anyone undertaking a phenomenological study would find the domain of phenomenological literature the most helpful source of meaning. For example, if one were to study some aspect of computer use or computer communication then the literature about the philosophy of technology by phenomenologists such as Heidegger and Ihde is a necessary source. Moreover, there are phenomenologists such as Hubert Dreyfus who have written specifically about computers from a phenomenological perspective.
