Why is the USP–NF Spanish Edition in three volumes? How is content divided?
A. Beginning in 2007, USP expanded the print format to enhance readability, usability, and comprehension as well as allow room for future expansion. Each year, new content is added to reflect revisions, and USP–NF was close to exceeding print industry page and binding limits. In efforts to accommodate future growth as well as keep the volumes equal in page size, a 3–volume format was selected. The 3–volume print format applies to both English and Spanish editions.When dividing content, USP took into consideration how subscribers use the USP–NF and tailored the volumes to maintain ease of use, i.e. keeping API monographs next to dosage form monographs in alphabetical order. To help users find specific information, all volumes contain a full table of contents and index.
