An updated version of PubMed is now available at https://pubmed.ncbi.nlm.nih.gov/. The new PubMed will become the default in spring 2020 and will ultimately replace the legacy version. The new responsive layout offers better support for accessing PubMed content with the increasingly popular small-screen devices such as mobile phones and tablets. Find highly relevant articles more easily using the Best Match sort, now the default sort order in PubMed. Best Match uses a machine learning algorithm that is trained on aggregated user searches. The Best Match algorithm ranks search results according to several relevance signals.

Some things will stay the same including:

• Access the same trusted database of more than 30 million citations for biomedical literature.
• Filters to customize your search results.
• Use the "Results by Year" graph to see trends in literature over time or to refine your search results by publication year.
• Save your search results to a file, email your results to yourself or a colleague, or send your results to a clipboard, collection, or your NCBI My Bibliography.
• Go to the advanced search page to search for terms in a specific field, see the search details, review your search history and combine searches to create complex search strings.
• Save your search and create an email alert.

NLM will continue adding features and improving the user experience, ensuring that PubMed remains a trusted and accessible source of biomedical literature today and in the future.
