Q. Dear Sir I'm researching about e-textbooks in school...usage.. (Thesis, papers, dissertations) Can you help me?Thank you in advance Best

I began with the ERIC database and did a search with the terms "technology in education" AND "ebooks".  This returned around 40 results that included information on the use of ebooks in education. Hopefully that is enough to get you started and lead to other helpful resources. Thanks!
