This study analyzes data collected between 2000 and 2013 from the annual National Center for Education Statistics (NCES) Common Core of Data (CCD) Local Education Agency (School District) Universe Survey; the NCES Schools and Staffing Survey (SASS); and the U.S. Census Bureau Small Area Income and Poverty Estimates Survey (SAIPE). The findings presented in this study show substantial differences in student access to public school library/media centers, to librarians/media specialists, and to up-to-date library/media resources. Few gaps in library/media center resources have been reduced between schools, and gaps in the professional staffing of library/media centers are still widely apparent. While the study findings show that the poorest students have the least access to certain resources and particularly to librarians/media specialists, it is clear that ethnic minority status has an even stronger association with student access to library/media center resources than does poverty level.
