eCollectica’s pioneering development of online eGuides fundamentally changes the nature of reference book creation and distribution. Instead of having to wait months or years to update and revise a book, changes can be made in a matter of days or weeks. New material can be added to each eGuide as it becomes available, with none of the printing costs or physical space limitations imposed by traditional publishing methods. Thousands of high quality color photographs can be shown without regard to the high cost of printed reproduction. Keyword searching allows users to find relevant information quickly, and choices of display options offer flexibility that is unavailable with print.
