Dragonfly
Summer 2003 -- Volume 34, Number 3 |

Last month, the National Library of Medicine made access to free full-text on the Web more convenient for PubMed users, LinkOut libraries, and DOCLINE sites.
1. PubMed now features an icon in the Summary results display
that indicates references to articles that are available free
online: 
. This icon joins those that identify
references to journals in PubMed Central, references with
abstracts but not available free online, and references without
abstracts or free online availability.
These are the icons that PubMed uses in its Summary
display:
No Abstract
The citation has neither an abstract nor a link to free full
text. Clicking on the icon displays the Abstract format (albeit
without an abstract) which may display a link to another source
for the full text of the article.
Abstract
The citation has an abstract, but not a link to free full text.
Clicking on the icon displays the Abstract format which may
display a link to another source for the full text of the
article.
Free Full Text
Full text for this article is available free. Clicking on the
icon displays the Abstract format with an icon that will link you
to the full text at no charge from the publisher's source. There
may or may not be an abstract in PubMed (if not, the citation
will display "No abstract available").
Free in PubMed Central
Full text for this article is available free from the PubMed
Central (PMC) site. Clicking on the icon displays the Abstract
format with the PubMed Central icon. Click on this icon to go to
the full text in PMC.
In a related development, you can now restrict your PubMed searches to citations with free online full text using the new subset: free full text [sb]. For details, see "Technical Notes: Free Full Text Subset Available for PubMed Searching" [c]. (NLM Tech Bull 2003 May-Jun:(332):e1)
2. LinkOut libraries now have a quick way to learn which LinkOut journals supply free full text online: consult the "Free LinkOut Journals by Provider" list [http://www.ncbi.nlm.nih.gov/entrez/journals/free_prov/free_full_prov.html]. Then, by using the LinkOut Holdings Submission Utility to enter your library's holdings for these titles, your library's LinkOut icon will provide an additional pathway to lead your users to the electronic full text of references that they find in PubMed.
NOTE: This new "Free LinkOut Journals by Provider" list includes the free online full text that is available from HighWire Press. You can use this list instead of going to the HighWire Press site, as described in the now-obsolete previous section of this series, "Free Full-Text Journals on the Web, Part IV: Using LinkOut with Highwire Press" [http://nnlm.gov/pnr/news/200304/pmcpart4.html].
3. Over the past few years, DOCLINE libraries have received numerous requests from their users for copies of articles that were available online for free. These copies have been requested from other libraries via DOCLINE. These requests-for content that users could have read immediately on their computer screens-have had unfortunate costs in delayed information access and superfluous personnel effort. However, until last month, these unnecessary requests were almost inevitable because it was so difficult to identify the PubMed citations to free full text. DOCLINE libraries should now receive far fewer of these unnecessary requests as their users are presented with clearer routes to the content they want, thanks to the new Free Full Text icon in the PubMed Summary display and the easy way for LinkOut libraries to find free LinkOut journals. If any references to free full text slip through-if a library receives a request from a user for a copy of one of these free articles-the library will be alerted by the Free Full Text icon when it uses PubMed to create a DOCLINE request. In addition, the DOCLINE system will provide an automatic notification whenever a library submits a request for an article that is available free at PubMed Central by providing a link to the article's text:
