Most of the journals and magazines in Stephen Hawking's office were transient items, which would have entered upon publication, and gradually circulated out in a relatively short time frame. The vast majority of such items in the office date from the last years of Stephen's life, from 2015 onwards, and haphazardly reflect on subscriptions, affiliations and societies where he happened to be most active at that moment in time.
