Most of SECED's evening meetings are recorded, including the biennial Mallet-Milne Lecture. The recordings are managed by the ICE and are made available for a year after the event (typically). Follow the link to ICE's Events Archive to see recent and recorded events that are available online. SECED members (and ICE members) get exclusive early access to recorded lectures for an initial period of three months after the event. You will need to log in to MyICE to see exclusive material. After the initial period, recordings are made available to all users.
