Utopia Documents
Utopia Documents is a semantic, scientific, web-enabled PDF reader that is part of the Utopia toolset. Utopia Documents can be downloaded for free. Utopia provides links to web resources and metadata. Although Utopia is a PDF-reader, it bridges the web-connectivity gap with HTML content by making normally static PDFs fully web-enabled (as long as the user is online). Since June 2, 2014, Utopia Documents changed their license to become open source under GPLv3. Versions. Utopia Documents v. 3.1 is available for Microsoft Windows (XP, Vista and Windows 7), Mac (OS X 10.6 (Snow Leopard ) and above) and Linux (beta). Software Features. Utopia Documents can be used in the same way as any other PDF reader, such as Adobe Acrobat Reader or the Preview application on a Mac. The application's workspace is split into three main panes (which can be collapsed): the PDF file itself is displayed on the left, a 'pager' is displayed at the bottom, and a sidebar to the right. The pager allows you to scan back and forth through the document and to move rapidly from one page to another. Although you can use Utopia Documents to look at any  PDF file, the software really comes into its own as a reader for scholarly papers in the biomedical and biochemical fields. Data Sources.
