Free Mendeley is free Academic software which is available across a number of different platforms. You can run Mendeley on your computer or laptop, your phone or tablet, and also access it from any modern browser. You can either download the appropriate app for your particular device, or use your web browser to log onto the web version. Mendeley acts as a repository for your reference information. You add papers to your library by importing PDF files stored on your computer, or by retrieving them from other locations - like online catalogs such as ScienceDirect, Scopus, Pubmed or PLOS. You can also create entries for items that you don’t have access to as PDFs by manually entering details.
