WISER (or Workshops in Information Skills and Electronic Resources) is a programme of classes designed to help you to make effective use of electronic and other library resources in your research and learning. Although the workshops are free, booking is essential, and can be done via the page above or the OUCS website.
WISER sessions give you all sorts of tips and guidance on how to search for books, journals, and electronic resources on SOLO, OxLIP+ and other catalogues, as well as on how to manage your research and references effectively. If one of your New Years resolutions is to improve your information skills, it would be well worth your time signing up for a few!
