ubMed LinkOut has some exciting new features for libraries:
- LinkOut has lifted the daily limit for new SERHOLD® participants,
- it's now easier to provide a library icon, and
- new documentation is available.
LinkOut is a feature of Entrez that provides users with links to web-accessible relevant resources
from PubMed and other Entrez databases. LinkOut for Libraries allows for the display of both SERHOLD
print holdings and electronic full-text links directly from a PubMed search (see Figure 1).
LinkOut is a free service provided by the National Center for Biotechnology Information (NCBI) at the
National Library of Medicine (NLM).
Display of SERHOLD Print Holdings
Library patrons can see their library's SERHOLD print holdings information in PubMed while they are
searching from the library, home, or at the office. LinkOut is welcoming participation from SERHOLD
libraries. There is no longer a daily limit for new participants.
After you sign up for LinkOut, simply add the SERHOLD information for your library in the
LinkOut Library Submission Utility (see Figure 2). You will need the LIBID(s) for your
library, and a brief description of where holdings are located. Information from SERHOLD
will be copied to LinkOut by 12:00 PM ET the following business day.
Provide Library Icon
Provide Icon is a new feature of the Library Submission Utility. A library can now upload an icon to be
stored at NCBI. Libraries can still choose to provide the URL to an icon file stored at their Web site.
A new tutorial for libraries, Setting Up LinkOut for Libraries, is a step-by-step guide on
how to set up LinkOut at your library. Topics include getting an account, entering library information,
entering electronic holdings, adding SERHOLD print holdings, and displaying the library icons in a PubMed
search. View the tutorial at:
We also updated the document LinkOut and Library Holdings. Check it out at:
