The National Library of Medicine (NLM) continues to develop features in the new PubMed site, which will replace the legacy PubMed in late spring 2020. Several features have been recently added or updated in the new PubMed:
The summary display format has been updated to include more citation details, such as the full author list. Labels indicating retractions and other important updates to the original publication are included, as well as labels for free articles when a link to the free full-text article is available. Also, you can now download citations in PubMed format, which matches the MEDLINE format from the legacy site. The PubMed format uses Unicode UTF-8 character encoding; diacritics such as accent marks will now be preserved in your exported file. Citations can be saved in PubMed format as a text (.txt) file or an .nbib file for use with citation management software. See Save citations as a text file and Cite an article in the PubMed User Guide for more information.
The RIS file format has been removed and replaced with PubMed format. The PubMed format provides the complete bibliographic data—including PubMed specific fields—requested by many users, which the RIS format could not accommodate. See PubMed format in the PubMed User Guide for more information about the data included in PubMed format.
Send to: Citation manager is available with the same functionality as in the legacy PubMed. Use Send to: Citation Manager to export citations in PubMed format as an .nbib file, which can be used by many citation management programs. See Export citations into citation management software in the PubMed User Guide. Individual term translations are included with the search details in History, available on the Advanced Search page. Translations show how each term was processed using PubMed’s search rules and syntax. For example, PubMed may modify or add terms to a search to optimize retrieval, such as: MeSH terms, British/American spellings, singular/plural word forms, and other synonyms. See How PubMed works: Automatic Term Mapping (ATM) in the PubMed User Guide.
Citations in the Clipboard are represented in your History by the search number #0, which may be used in Boolean search statements. For example, to limit the citations you have collected in the Clipboard to English language articles, use the following search: #0 AND english [la]. This does not affect or replace the Clipboard contents. See Save citations temporarily using the Clipboard and History in the PubMed User Guide for more information.
