NCBI’s new PubReader display format in PubMed Central (PMC) makes full-text research papers not only more readable but also more portable. PubReader is an alternative web presentation that offers another, more reader-friendly view of the articles in the PMC archive. Designed particularly for enhancing the readability of PMC journal articles on tablets and other small-screen devices, PubReader can also be used on desktops and laptops and from multiple web browsers. If an article retrieved by a PubMed search is available from PubMed Central, it will appear in PubReader format. In PubMed Central searches, PubReader will be one of the viewing options. The CSS and JavaScript code used to create the PubReader display is freely available from NCBITools on the public code repository GitHub.
