PubMed Relevance Sort – Coming Soon

Tuesday, September 17th, 2013

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.

Changes Coming to Author Affiliations in MEDLINE/PubMed

Thursday, September 12th, 2013

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.

What’s Your Query Number?

Friday, August 30th, 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:

How is New MeSH Vocabulary Identified?

Friday, March 1st, 2013

New MeSH vocabulary is identified in one of three ways:

1. National Library of Medicine Indexers identify gaps in the vocabulary and forward the concepts to the MeSH staff.

2. NLM MeSH reviewers identify needed terms during the regular process of topic review.

3. Users alert the MeSH staff to new terms using the MeSH Suggestion page:
