A professional association journal should reflect the needs of its organization, its readers, and the field it represents. Evaluating the needs that the has met, and those it has not, is essential if it is to remain relevant to its readers.(1) Describe the characteristics of articles published from 1985 through 2018. (2) Describe content intended to educate lactation support providers and clinicians. (3) Explore the ways the content has illustrated the growth and development of lactation knowledge, and (4) identify the reoccurring content threads consistent throughout the 34 years.A prospective mixed methods approach incorporating a quantitative content analysis and a qualitative thematic analysis was used. Frequency distributions were done on all the variables extracted from published articles ( = 1586). The second level of analysis identified themes using an iterative and consensus approach.Mirroring the growth in the lactation field, the volume of research articles published each year has increased along with the percent of research articles per issue. Research methods have become more diverse. The international scope and relevance, while always present, has been steadily increasing. Threads identified were; striving for international scope, advancing lactation education, developing a body of knowledge that informs clinical practice in lactation, and creating a centralized place for multidisciplinary research about lactation.The body of work published in the parallels the development of the lactation specialty. We have highlighted areas for improvement and possible further study.
