Use the Web Importer browser extension when viewing a citation record, or a list of search results in databases such as PubMed, Google Scholar, or a website or a webpage, such as an article on the LA Times website.
As you add the citation(s) to your library, the Web Importer attempt to add the PDF to your library. Click on the ... at the bottom of the Web Importer pane to change this setting.
If the Web Importer does not work well, look for an options such as Cite/Save Citation/Export or a quotation mark icon to save or export the citation in RIS format. Depending on the database,
- you may be able to directly export to Mendeley, or
- you may have to save the RIS file and then import it into your library by clicking + Add new > File(s) from computer.
You may have to try out different methods. Note: RIS files are universally compatible with reference managers, regardless of platform or tool.
