Electronic Resources invoices from Collection Management

Occasionally Collection Management student workers have left ER invoices at the Reference desk when the outside door to 144 is closed.
I've asked that they not do this anymore because I don't want to make anyone else responsible for getting it to me or opening the door when patrons may need help at the Reference desk.
If a student worker forgets, please feel free to ask them to try again or have a CM staff member leave it in my box. Thanks.
