As such, classprints are neither used to circumvent copyright laws nor discourage purchase of text material, nor subscription to the journal from which the information was extracted. Students are provided with classprint documents for a specified time during the course to take notes. In any citation of information the user must make appropriate reference to the work using accepted bibliographic style and form. Images from deep space used in teaching come in all shapes and sizes as shuttle photos, as well as, satellite and computer-generated images.
Visualization is distinguished as the representation of data using software tools.
Imaging and visualization tools reshape old questions by changing their orientation and focus. New research styles are needed for analyzing data and producing scientific findings. But storing vast numbers of images creates a burden for educators as consumers of this data form. The vast image treasury of original and unique data must be archived since it will not be superseded in the near future. Once obtained, image data must be archived, catalogued, and accessed easily.
