Who plans for new and renovated libraries? Architects deploy master planning–based analyses to guide future development over the long term, heavily tilted toward analytical conclusions. In contrast, librarians tend to deploy design theory—solving problems in iterative solutions and redesigning for changing problems. Building and renovation projects inevitably bring interplay among groups (architectural firms, governing and financing entities) with their own influences, lenses of analysis, and social positioning. This study seeks to answer this question: Have we been or are we engaged in building or renovating libraries around master planning (architects), or are we solving library problems (design theory and librarians)? And what does the answer tell us about libraries and how they are being guided and shaped as they are built and renovated? A discourse analysis is performed on a sample of 15 years of library literature on building and renovation plans to answer the question.
