Did you know that you could read books online through Universities libraries. Have a look at some of them accessible from Campus UNED:
Thomas, Michael Ed. (2008) Handbook of Research on Web 2.0 and Second Language Learning, Hershey, PA, USA: IGI Global
http://site.ebrary.com/lib/unedbiblioteca/docDetail.action?docID=10257349 (ebrary books) To read a sample of book chapter, just select one of them.
Naidu (2010) A textbook of Engineering, Pearson Education India http://proquest.safaribooksonline.com.ezproxy.uned.es/book/-/9788131775073 (Safari books) More focussed on teaching science because of the amount of exercised found on it, but you could find many other examples of research books within Safari books online (http://proquest.safaribooksonline.com.ezproxy.uned.es/). Remember to be logged before reading.
This one could probably belong to a thesis publication http://ieeexplore.ieee.org.ezproxy.uned.es/stamp/stamp.jsp?tp=&arnumber=4782329
