Whilst Departments are responsible for delivering your course, they have so much more to offer students.
Libraries
You will most likely use your library to access readings for your specific course, but many libraries host additional workshops or offer guidance on anything from researching to referencing. Librarians can also help you find relevant texts (both online and physical copies) and are happy for you to recommend texts that they don't yet have. Remember, you can sign up for libraries attached to other Departments, either because they house useful texts for your course or because you're interested in their contents.
Research Centres
Research Centres are established centres within the Department which undertake wordclass research in a particular field. They produce rigorous, original and significant contributions to knowledge. Postgraduate students may be more likely to engage with these centres than undergraduate students, but they often host events which are open to all.
Reading groups
Some Departments may have reading groups, which are often student-led. These can be an informal environment in which to discuss a shared interest in a specific topic relevant to your Department. They will often be advertised on the Department website, social media or any physical noticeboards.
Academic representatives
Academic representatives are elected to act as the voice of students in Faculties, Departments or Schools. They are the person you should approach if you have any comments or concerns about your course and the wider Department that you want heard. You can learn more about the role of academic reps on the Cambridge Students' Union website.
If you would like to see what support might be available from your own Department, have a look at the Department directory and visit your Departmental website for more details.
