Library staff have created online guides called "Libguides" to help you find relevant resources for your studies. The menu on the left lists subject-specific guides written by Continuing Education Library staff, which will be especially relevant to Continuing Education students. The list of Continuing Education guides is also available at http://ox.libguides.com/conted.
There are also guides written by other Bodleian Libraries staff which you may find useful. You can see a list of all available guides at Oxford Libguides.
