I love to pick a topic and browse the shelf at the library. The shelves start with a basic section on the subject and then break out a number of specialty sections. A basic example might be World War II, would break out sections on the war in Europe and the war in the Pacific. Also I might find a section on Naval warfare, tank warfare, submarine warfare, and air warfare. Additional sections might be the politics of the war, the economics of the war, and the social effects of the war. I might breeze through the sections on tank warfare and naval warfare but spend more time in submarine warfare and the Air war. How do I do this in Logos? If I go to the library and sort by subject, I get all the a's followed by all the b's. I want similar subjects together. The library systems (either the Dewey Decimal System or the Library of Congress System) are well designed with a hierarchal system of subjects in a published book. If you have a lot of books in a subject area you open up a number of the sub-subjects and sub-sub-subjects. If you only have a few cooking books then all might be in Cooking, if you have more you use Italian cooking, and Chinese cooking in addition to the general Cooking subject heading when designing your library. Can I do this in Logos. I would love to learn that you have used the Library of Congress system and Subject headings and I have not found a way to view the LC numbers. Maybe you could consider this a suggestion. Libraries have spent years perfecting this system. It would be a shame not to use it and a waste of time to re-invent the system. Can I do this now.?
