Table L7 provides ranges of Cutter numbers, with no directions for the allocation of the numbers within the ranges. For an extensive collection such as a library might assemble of its parent institution's output, more guidance is needed. Between normal institutional changes and multiple catalogers of varying degrees of expertise, the chances of maintaining a logical shelf arrangement over time become vanishingly small. This case study describes the problem that developed as the table was applied to the institutional publications of Georgia State University, and proposes an explicit expansion of Table L7 for local use as a solution. With suitable adaptations to accommodate their specific administrative and academic divisions, this expansion of Table L7 could be helpful to other "one-number institutions" using both Table L7 and Table L13.
