Historical Data
Both David and Grant have hit on the problems with the collection, storage and dissemination of historical data, especially technical data, in Canada which includes: security classification, no central repository of information, a lack of interest in collecting and archiving the material and even less interest in making it available to the public. With respect to Canadian vehicle data, essentially little is saved and most of this material ends up in landfills. The move to digital manuals has exacerbated the problem with tighter controls on the data and the ease in which it can be erased.
