N LM® is pleased to announce a redesign of the PubMed interface. While retaining the robust functionality, the interface was simplified to make it easier to use while promoting scientific discovery.

The changes to PubMed are outlined below. Please note that search processing, including Automatic Term Mapping, has not changed.

PubMed Homepage

The PubMed homepage has been streamlined, requiring less effort to find resources. The new homepage includes an NCBI Header, Search Bar, and Footer that are common to all PubMed pages (see Figure 1).

The NCBI Header includes an NCBI Resources pull-down menu categorized by topic, a How To menu, and the Sign In for My NCBI.

The Search Bar retains the database selection menu, and includes a link to Advanced search and Help. Additional Search bar selections, RSS and Save search, display after running a PubMed search.

The Go button is now the Search button.

Access to the popular tools and resources previously found on the PubMed homepage sidebar may be found under PubMed Tools (e.g., the Single Citation Matcher and Clinical Queries) and More Resources (e.g., New and Noteworthy and the PubMed Tutorials).

The Footer includes links to many NCBI resources.

The Limits, Preview/Index, History and Details tabs' features have been consolidated in Advanced search.

Summary Results

Changes to the Summary format include these modifications (see Figure 2):

My NCBI Filters

Filter your results, on the right of the screen, has replaced the Filter tabs (see Figure 2). It provides Manage Filters, a quick link to change filter selections. Free Full Text has been added as a default filter option for users not signed in to My NCBI. Click on the filter link to display the filter contents. A plus sign, will display which if clicked, will add a search for that filter to the search box.


Limits (which can be activated on the Advanced search page) appear on the upper right of the screen, with links to change or remove them (see Figure 3).

Related Data

Find related data has replaced the database "Links" selections previously available on the Display pull-down menu. After selecting a database from the menu, a database-specific options menu will display if more than one option is available, as well as a description of how the related data were generated (see Figure 3).

Display Formats

The display formats have been modified and include the following options:


The Brief, Citation, and AbstractPlus formats are no longer available. The MEDLINE, XML, and PMID List display only in text format.

Display Settings

The Display Settings menu replaces the Display, Show and Sort By menus.

The consolidated Display Settings menu should be used to change results to a different display format, change the number of items per page, and the sort parameter. Make your selection(s), then use the Apply button (see Figure 5).

Send to (destination options)

The Send to menu should be used to send citations to a File, Clipboard, Collections, E-mail or to Order (see Figure 6). Use Send to File and select the MEDLINE format to download records for use with reference management software.

The RSS feature was moved from the Send to menu to the Search bar. The Send to Printer option was removed; use your browser's print options to print records.


A Clipboard link will display after sending citations to the Clipboard. Click the Clipboard number of items link to display the Clipboard contents (see Figure 7).

Individual citations in the Clipboard include a Remove from clipboard option. In addition, Remove all items displays at the top of the Clipboard page; this option changes to Remove selected items when using the check boxes to select items to delete.

Advanced search

The Advanced search page was modified to use the redesign look and feel. Changes include:

PubMed Help

The PubMed Help has been updated to reflect the redesign changes.

Discovery Ads

The discovery ads and search sensors have been modified slightly to ensure the ads fit well in the new design. One significant change is some Summary results discovery ads, which are generated based on a user's search terms, will display in the discovery column when displaying multiple records in the Abstract format. A single record displayed in the Abstract format will include the discovery ads for the particular citation.


My NCBI was updated with the following changes:

[Editor's note: These changes were implemented in PubMed on October 14, 2009.]
