The impending release of Kalmbach's Model Railroader DVD set bodes well for the volumetrically challenged. Experience with the previously released Trains DVD set indicates that the useage pattern is reference and research, not relaxing reading. The intergrated ability to search the content is invaluable; offering an improvement over the online database searches which require you to then paw through the pulp stacks looking for the elusive issue. Switching to digital in this case should save me between 6-8 cubic feet of shelf space; a valuable commodity. If RMC, Mainline Modeler, and the NG&SL Gazette were similarly offered, a further 8-10 cubic feet could be reclaimed.
