Prior text-related research has used variables that were not clearly described or defined, could not be directly compared from one study or time period to the next, or were applied inappropriately. Measurements of typography-related and substrate-related variables may have absolute or relative values, and confusion can arise if the variables are not clearly identified and defined. The study is an integrative review with mixed methods research design investigating 44 books and two websites (part 1), and 83 journal articles and four theses/dissertations (part 2). The integrative review shows that the sources investigated present neither essential information on typographic and substrate characteristics nor consistent definitions of legibility and readability in order to allow comparable replication from one study to another. Findings are displayed in Chapter 4. Discussion and the related details are presented in Chapter 5.ETDIn Copyrightintegrative reviewtypographysubstratelegibilityreadabilityDissertation
