From the summary:
AASL is sponsoring a longitudinal survey that will provide data on the health of the nation’s school library programs. The annual survey is open to library centers at all schools teaching at the primary and secondary levels. The first survey was conducted in 2007, with annual results posted each year. Most of the questions are tracking questions, though each year the survey includes a short series of topical questions.
