• A pattern of rapid, scalable literacy assessment paired with health-communication alignment, emphasizing quick screening and readability gaps in medical settings. Evidence seen in Rapid assessment of literacy levels of adult primary care patients [1], The gap between patient reading comprehension and the readability of patient education materials [5], and Rapid Estimate of Adult Literacy in Medicine [17].

• Literacy is framed as a social practice shaped by context, politics, and participation; ethnographic and critical approaches examine how power, culture, and social change mediate literacy. Supported by Social Literacies [4], Learning, Literacy, and Participation [11], and Other people's words [14].

• Adult education theory and practice examining motivation, participation patterns, and learning in adulthood, integrating Knowlesian theories, self-directed learning, and transformational perspectives. See Motivational Profiles of Adult Basic Education Students [20], Participation Patterns in Adult Literacy Programs [16], Learning in Adulthood [10], Leadership for literacy [7], and Learning in adulthood: a comprehensive guide [6].

• Policy-oriented and national studies tracing governance, leadership, and global trends shaping adult literacy, including Canada and cross-national perspectives. Evidenced by Adult Literacy in Canada [8], The World Crisis in Adult Education [9], and Leadership for literacy [7].

• Historical and conceptual investigations track how literacy has been defined, taught, and valued across eras, linking schooling history and contemporary practice. See The Labyrinths of Literacy [2], Looking Back in Anger [19], Literacy in the United States [15], and Bringing Literacy to Life [18].
