The two planned update disks will include enhanced video offerings. The table of contents can be expanded or collapsed by double-clicking on a section. Key features include Search Sets, which allow creation of custom groups of frequently sought subjects. The CD allows you to see helpful hints and tool bar tips at start-up, then to delete this option once the CD has become familiar to you. Search preferences can be customized.
Navigation is fairly easy.
The table of contents outline has a synchronize option, so it will follow you through your searches keeping you from getting lost. I had the feeling I was able to beam myself back and forth from a satellite view of the world of current medical knowledge to a bedside or even microscopic view of a disease process. The functionality of the searches is pretty much the same as in the previous Harrison's CD release. Potential buyers may want to note that an Internet version is in testing, which, when released, would be accessed via a purchased password. That edition will be continuously updated but may also be limited by the relative slowness of current Internet graphic capabilities, compared with the available CD-ROM version.
