The idea to the ANDEMIA online course manual is based on the challenge that resources for sending ANDEMIA students to a variety of face to face courses is limited not only due to financial but also time constraints. Online course provide a good basis for the students, Master, PhD and Post Docs to provide them with an overview about certain topics and help them to identify their own gaps and needs. They can create more interest for a specific field and build demand for more advanced knowledge on specific topics. The courses and resources in this manual are meant to reflect a variety of online courses selected from different universities and organisations on topics perceived to be useful for ANDEMIA students. Albeit not complete, we believe that the selection of courses in this manual covers quite comprehensively a wide range of topics.
