As a member of HYMS you may receive University of Hull and/or York email accounts as well as one for HYMS. You are strongly encouraged to set up forwards from these accounts to your HYMS email. This will help ensure you do not miss out on any relevant information from the two universities including overdue notices etc. from the two libraries.
Details on how to do this are available from the HYMS it webpages at http://itservices.hyms.ac.uk/new-users#1styearregistrationguide
