Deep Blue and PubMed LinkOut: A Higher Profile for University of Michigan Research
Researchers who find articles by University of Michigan (UM) authors in PubMed can now directly-and for free-link to the full text using Deep Blue, UM’s digital repository, via PubMed’s LinkOut feature. Deep Blue is an online archive that preserves and provides access to UM intellectual and creative work. It is the first institutional repository to provide such links.
To see all the items in Deep Blue that are in PubMed, enter “loprovdeepblue [sb]” in the PubMed search box. At this posting, there are over 8,800 articles.
I don’t find a way to add the Deep Blue collection in the LinkOut submission utility, and I don’t see a “free full text” button on the abstracts. However, Deep Blue’s link icon can be added to a library’s shared MyNCBI account; use Configure > PubMed > LinkOut > Miscellaneous > MLibrary (Deep Blue) (DeepBlue).
