Start with ERIC, the primary database for education. JStor is a favorite for educational policy studies. APA Psycinfo is also great.
Other Databases from independent vendors:
ERIC documents are items in the ERIC database that are generally not available in journals or books. They are often technical reports, curriculum materials, or papers presented at conferences. You can always distinguish an "ERIC document" from a journal article by looking at the ERIC number or accession number. This will begin with ED if it a document. Journal articles begin with EJ. If the ERIC document is not available online, you will need to access it on microfiche. If you are unable to find the document online or on microfiche, submit an Interlibrary Loan Request.
University Library holdings of ERIC microfiche:
The cabinets housing the microfiche are located on the first floor of Atlanta Library North and are labeled ERIC Documents. The fiche are filed in order by their ED number.
