Thank you for your enquiry. It is good academic practice to keep a record of all materials consulted - and by the same token requested - when researching an assignment.
The Document Supply process for digital items delivered by Secure Electronic Delivery (SED) is automatic and the item is automatically posted to your University email account.
http://lrweb.beds.ac.uk/libraryservices/docsupply/document-supply-q-and-a/sed
The item won't appear on your library record and you would have to email the Document Supply team to get a report on progress (your ID number would be sufficient if you couldn't remember the details of your request)
docsupply@beds.ac.uk
This is unless the digital item cannot be supplied. In those rare instances you would be emailed directly by the Document Supply team to be told what the problem is.
The Document Supply team can provide, on request, a list of outstanding SED requested items. You can email the team or ask at the Customer Service Desk, staff can print it off the list of outstanding requests or
show you them.
If your request is for an article, chapter or paper for print delivery you can view these items on your Library Account
