The Library as Intellectual Commons and Private Right

Sor Juana assembled a remarkable library—thousands of books—which she guarded jealously as both personal property and intellectual resource. Yet she also shared access with trusted scholars and saw her collection as contributing to human knowledge. This reveals the complexity of knowledge property: it is not scarce in the way land or tools are, yet effort, cost, and curation make collections valuable. In libertarian justice, Sor Juana's library illustrates that knowledge can simultaneously be: individual property (she owned the physical books and had the right to exclude unauthorized access), a shared resource (she chose to lend and discuss ideas with others), and a contribution to culture (her reading informed her writing, which circulated). This concept refuses the false choice between pure commons and pure exclusivity. Libertarian property rights protect individuals' choices about sharing or withholding, while acknowledging that knowledge often flows beyond formal ownership boundaries. Sor Juana's library model suggests that freedom includes the right to accumulate, curate, and selectively share intellectual resources without coercive redistribution.
