The realm of science and engineering is driven by science and technology. These disciplines are used to work in the online realm and many of the resources are readily available online. This ranges from online books, datasets, and journals. In the area of online textbook access, this has largely been neglected as the library was able to provide physical reserves, so electronic access for textbooks have been driven by the publishing industry. This means that finding electronic access to a textbook will be daunting and there is a need to consider OA resources for the science and engineering disciplines.
