For example, Geology isn't just about rocks, and physics isn't limited to The Standard Model. And taking the beaten track doesn't guarantee high content. Like dark matter, most of what can be found on the network resides on The Invisible Web. It's off-the-grid, but only insofar as lying outside the conventionally accepted perception of what can be trusted, like a brand name. For instance, Google's database represents at most 20% of what's out there; it's based on traffic, staying on the highways, bypassing off-ramps.

Varying levels of exposition--varying degrees of difficulty--in material and the method of its presentation--the visual layout (is it clear or confusing?)--are important considerations. Seeing the same thing through different lenses increases the chances of understanding a concept or appreciating a description. A synopsis, hitting all the high points of whatever, is often more enlightening than an in-depth academic report. Current ideas are not only defined and expounded upon by learned science writers of news and ezine articles, and by academics and professionals through journals and preprint repositories, but also are interpreted on the layman-level by those who work in the field or by knowledgeable individuals who have a deep interest in the subject.

Classification and organization are overriding concerns. There are considerable overlaps; where does one place specific information? Stem-cell exposition and news would naturally fall in the Medical context, but also applies under the study of Biology--cell and molecular biology, genetics. The idea of an Ecosystem, defined as a complex set of relationships among the living resources, habitats, and residents of an area, taken as a whole, falls within biology, but also can be placed under Earth Sciences--Physical Geography, Environmental Geology, Biomes.

As well, certain ideas and principles are found to be common denominators, and fields can encompass a wide range of subfields. For example: self-organization finds a home in Biology, Physics, and Chemistry. Mathematics (Chaos Theory) runs through a number of subfields including Geodynamics--earthquakes, avalanches, and weather. And Oceanography is defined as the science that examines the biology, chemistry, physics, and geology of oceans. Could anything be more inter-disciplinary?
