To celebrate National Library Week next week (April 14-20) Oxford University Press is offering free online access to the Oxford English Dictionary (OED) and Oxford Reference in North and South America.
From the OUP Blog:
Free access will be through a username and password announced here on the OUPblog on 14 April. Everyone will have access through the same login, which will last until the end of the week.
We’re freeing up this unprecedented amount of OUP content in thanks for all the hard and vital work that librarians do to support their patrons and in celebration of the week honoring libraries. In addition, we will be announcing a special contest just for librarians on 14 April, which will bring attention to the events that libraries hold during National Library Week.
