To celebrate International Open Access Week 2017 we have put together a duo of at-a-glance ready reference guides – one for authors and one for readers of Open Access materials. The pdf guides are available in a handy “large postcard” size ideal for printing out and pinning to your noticeboard, or tucking into a folder. For readers, the theme is discovery and the guide highlights the variety of scholarly resources openly available to all and where to find them. For Cardiff University authors, the focus is on how to go about making your research open access with a visual step by step guide. The guides are available in both English and Welsh.
