Mek & Tosj today announced a major update to their 2007 Apple Design Award winning application Papers, a program which helps scientists on the Mac to create and organize their Personal Library of Scientific literature. The version 1.5 update brings over 100 new features and bug fixes and is the most significant update of Papers they’ve done to date. One of the biggest new features is the support for search engine plugins — it ships with built-in support for Google Scholar, Google Books, Pubmed, Scopus and Web of Science. Papers 1.5 is now also fully compatible with Mac OS X 10.5 Leopard, has an improved and streamlined user interface, and more tightly integrates with other applications in your literature workflow.[ Price: from €29 ~ Requires: Mac OS X 10.4 or later ~ Leopard support ]
