This might be worth a look for the ongoing search for the perfect information manager.
KnowledgeWorkshop is designed to help you manage and interconnect the information found on your PC and across the World Wide Web. It enables you to synthesize information into personal knowledge and understanding, in a manner that mimics the brain’s own mechanisms. It facilitates the generation of new insights and understanding from the relationships you can establish among your information sources leading to the “Aha!” experience.
Designed for the more casual user of information, KnowledgeWorkshop Personal Edition is ideal for individuals who are new to knowledge management and want to begin building a personal knowledge base. It is a simplified version of our professional product that is easier to learn, but still has the basic tools you need to make your information and knowledge work for you.
