Abstract
In this paper, I discuss "findability of information (=how easy to find information)" from a perspective of "usability(=how easy to use a system)." First of all, a relationship between usability and findability is considered. Based on the consideration, I indicate how usability can improve findability mentioning a concept of "form of information." Here again, I make it clear what information users can easily find and how a system would support it. Finally, as a summary of the discussion, I present general principles to implement a system with excellent findability.
