"The object of this study is to investigate some factors important to legibility. The problems tackled are mainly psychological and pedagogical in nature. A survey of previous research in the field is included...Two categories of problems related to typography are treated. One concerns the legibility of printed text. The other concerns the so-called congeniality value of type face and layout. Different approaches are employed. The first group of problems is studied experimentally, in terms of reading rate, eye-movements, comprehension, etc. The congeniality value is defined by attitude measurements." -- from introductory notes.
