On October 22, 2013 PubMed implemented the Sort by Relevance feature. Let us know what you think.
SciENcv is a new feature in My NCBI that helps users create an online professional profile that can be made public to share with others. Users can document their education, employment, research activities, publications, honors, research grants, and other professional contributions.
eRA Commons account holders who have linked their eRA account to My NCBI will find their SciENcv profile automatically populated with the information stored in their eRA Commons profile. You do not have to have an eRA Commons account to create a SciENcv profile.
Just in case you are not already a subscriber, the link to sign up for the U.S. National Library of Medicine’s Technical Bulletin is below. The TB (as they call it) is the source for the latest searching information about PubMed.
There are 3 subscription options:
- A once daily e-mail alert if an article is published or updated.
- A weekly notification of new or recently added content on the NLM Web site including NLM Technical Bulletin articles.
- RSS feed

PubMed will soon include a new relevance sort option. The “Relevance” sort option will be available from the “Display Settings” menu under the “Sort by” selections. The update to the new sort by selection will be combined with a new feature that retains the most recent “sort by” selection for subsequent search results until a different sort order is selected, or after eight hours of inactivity on the system.
Results for My NCBI users that are signed in with a modified default sort order will continue to display in the modified order until a different sort order is selected. A Relevance default sort selection in My NCBI PubMed Preferences will be added after the initial implementation of this new feature.
The relevance sort order for search results is based on an algorithm that analyzes each PubMed citation that includes the search terms. For each search query, “weight” is calculated for citations depending on how many search terms are found and in which fields they are found. In addition, recently-published articles are given a somewhat higher weight for sorting.

Beginning October 1, 2013, NLM will cease editing the Author Affiliation field in MEDLINE/PubMed citations. In the past, NLM policy was to carry affiliation for the first author only, quality control the data, and edit the field to add “USA” or e-mail address as appropriate. However, starting with the 2014 PubMed system in mid-December 2013, NLM will implement a new policy that allows publishers submitting XML citation data for MEDLINE indexed journals to submit Author Affiliations for each Author name, Investigator name or Corporate Author name.
To prepare for and support this change, NLM will cease quality control review and editing of the author affiliation field in the MEDLINE citation. Searchers who were using a PubMed search to limit to US authors as the first author should be aware that it will no longer be comprehensive as of October 1, 2013.
Previously, when building a search in PubMed using History on the Advanced Search page, users would choose the search numbers they wanted to combine by clicking the item (#1, #22, etc.) and that is what we would see in the search builder; numbers, not words. Now, when you combine previously run searches, the actual terms appear in the search builder. No more wondering what those numbers represent.
Here’s a quick video to demonstrate: http://www.screencast.com/t/3kbYUXhNxX
Be on the look out. PubMed will soon ask you to decipher a “captcha” on the Send to e-mail feature. This feature will combat spam issues.
