New Full Text Access Feature in PubMed: Institutional Repository LinkOut!

PubMed users can now see the icon that links to the full text deposited at an institutional repository (IR) using LinkOut. The LinkOut service provides links to full text, library holdings, and other relevant external resources from PubMed and other NCBI databases. Until this year, there were three quick ways to access full text articles from PubMed:

  • the publisher icon links to the journal web site (may require a subscription to the journal)
  • the PMC icon links to free full text in PubMed Central (PMC)
  • the DOI (Digital Object Identifier) links to the article on the journal web site (may require a subscription to the journal)

The new institutional repository icons will link to free full text of the article at an institutional repository that it is not freely available from the journal or PMC. When an IR is participating in this new LinkOut feature, the linking icon will display in the “Full text links” section next to the abstract in PubMed for any publication with a direct link to a full text that does not have another free full text link. The “LinkOut – more resources” section expands to show the same direct links to full text as the icons. All links to participating IRs will appear whether or not there is a free full text icon displayed in the “Full text links” section. There are only a few IRs participating in the free full text LinkOut at this time but these few already expand access to about 25,000 publications. Some academic and research institutions encourage or require authors to submit their publications in the IR, making them publicly accessible within the terms of publication at a journal. This is often called “green open access.” There might be an embargo period or delay after publication, as there can be with NIH-authored manuscripts in PMC. However, free full texts can be available as soon as an article is published.

LinkOut resources come from organizations that have applied to join LinkOut, providing information or data that are relevant to that specific publication. LinkOut participants include libraries, biological data repositories, and repositories like Dryad and Figshare. If you know of an IR that has publicly available free full texts beyond those available in PMC, please let them know about this service. A list of participating institutional repositories is available from the LinkOut Web site. Instructions for institutional repositories to join LinkOut are also available. For questions about participating in LinkOut, contact NLM. Additional details and sample screen displays are available in the NLM Technical Bulletin.

Connecting to NLM’s Hazardous Substances Data Bank Using PubMed and LinkOut

The National Library of Medicine’s LinkOut filters feature provides PubMed users with connections to web-accessible resources, including full-text articles, consumer health information, and supplementary data related to a PubMed citation. PubMed users can access information for over 5,700 Hazardous Substances Data Bank (HSDB) chemical substances via LinkOut. HSDB focuses on the toxicology of potentially hazardous chemicals.

To set up LinkOut to retrieve HSDB information:

  • If you don’t already have a free MyNCBI account, create one;
  • In the Filters box on your MyNCBI account page, click the “Manage filters” link;
  • Click on LinkOut from the “Select Category” option;
  • Click on the + next to the Chemical Information option;
  • Then click on the + next to the Toxicology option;
  • Check the two boxes next to HSDB–this saves these options.

Then run a search:

  • Log into your MyNCBI account and go to PubMed;
  • Run your search;
  • On the upper right side of the results page find “Filter your results;”
  • Click on the HSDB link;
  • Then click on a result;
  • Click on the HSDB icon. The link takes you to the HSDB record for chemical(s) mentioned in the article.

Please note that LinkOut is not available for citations marked as “In process.”

NLM Theater Presentations at MLA 2015

The NLM exhibit booth at the 2015 Annual Meeting of the Medical Library Association in Austin, TX, featured theater presentations to bring users up-to-date on several NLM products and services. The presentation recordings are captioned and accessible from the NLM Distance Education Program Resources page. The presentations include:

Note: To listen to the voice recordings and view the captions you may need the latest version of Flash® Player (download for free from the Adobe Web site). To maximize the presentation, use the Full Screen button. For more information, go to the NLM Technical Bulletin page.

New LinkOut Library Submission Utility Quick Tours!

Three new Quick Tours have been added to the LinkOut for Libraries Training and Educational Resources Web Page:

  • Uploading Icons demonstrates the different ways to upload an icon image into the Library Submission Utility.
  • Contact Info shows how to add, edit and delete contact information in the Library Submission Utility.
  • Library Info, PrId and NameAbbr explains where to find your library information such as ProviderId (PrId) and NameAbbr, which is the same as your User Name, in the Library Submission Utility. This information is frequently requested by library vendors.

These Quick Tours replace the “Library Submission Utility: An Introduction” Quick Tour. For more information, please visit the NLM Technical Bulletin.
