Oxford has recently changed some of its pricing for e-books offered by aggregators.  In some cases, you will now see Oxford titles offered through EBL costing up to 4 times the price of single-user options in ebrary or EbscoHost, because EBL gives limited multi-user access through its Non-linear Lending option.  Now that we can get limited multi-user access for ebrary titles through the Extended Access program (see previous post), buying an ebrary SUPO title may be a better option in these cases than EBL.
