New PubMed is coming!
New PubMed is coming!
PubMed is changing the look and feel but is also updating the functionalities.
The new PubMed will become the default on 18 May 2020, but the legacy of PubMed is still available. National Library of Medicine will continue to run the legacy system in parallel for a short period of time after the new PubMed becomes the default. During this time, both sites will continue to receive updates to citation data. After a short time, the legacy PubMed site will be retired.
Why changing PubMed?
The new PubMed is completely rebuilt on a new technology platform. This is important for the future sustainability and scalability of PubMed and other NCBI resources.
One of the most visible improvements is the responsive design of the new site. Responsive design means that the site can be used on any device – mobile, desktop, or tablet – with the same features and functionality. Previously, only a very basic version of PubMed was available on mobile.
The new PubMed includes also new syntax functionalities.
Some major changes
Some major changes in search syntax and search translations:
- Automatic Term Mapping has been augmented to include additional British and American spellings, singular and plural word forms, and other synonyms to provide more consistent and comprehensive search retrieval.
- Truncated terms are no longer limited to the first 600 variations of a term.
- Truncation no longer causes automatically phrase search.
The new PubMed is completely rebuilt with updated technology. Since legacy and new PubMed are two separate systems, citation counts will not always match up. Indexing is done at different times for each system, so additions, deletions (e.g., removing duplicates), or updates to records do not take effect at the same time in both places.
Collections and saved searches are stored in your My NCBI account and will continue to be available in the new site.
Where can I get help with using the new site?
