Sheffield Hallam pays for access to electronic books and journals for its students and staff to use, but there are still plenty of free online resources that everyone else can use.
Google Scholar is the academic side of the search engine. It's useful because it allows you to look for articles written by experts. Type in your key words, e.g. space exploration, and click Search. The search results that have links on the right-hand side are the ones you can use for free.
Search and preview millions of books from libraries and publishers worldwide. View the full-text of public domain (copyright free) books and see selected pages from other titles.
Open access resources are free to use online wherever you are working. Put your keywords into Library Search and then filter your results using the Open Access filter in the side bar. You can add extra filters to see only books or peer reviewed articles.
