From wikipedia page:
Change detection for GIS (geographical information systems) is a process that measures how the attributes of a particular area have changed between two or more time periods. Change detection often involves comparing aerial photographs or satellite imagery of the area taken at different times. The process is most frequently associated with environmental monitoring, natural resource management, or measuring urban development
How is the comparison done? With what tools?
I feel that the description is not complete. Or something is missing.
Where or in which books can I find more information about Change Detection?
What tools should I use to perform such an analysis using the data in a shapefile? (only open-source please)

Change detection is a common operation/module in remote sensing packages like ENVI or Orfeo toolbox. It usually involves raster data (satellite images for example).
Change detection is done by comparing two raster images that were taken at different times but which cover the same area. As the images cover the same area, the images overlay each other. Imagine two grids stacked on top of each other.
It is then a matter of comparing whether the value of a pixel in the new raster is the same as the value of the pixel in the old raster. Pixels that have changed are then marked. The output is usually a raster that covers the same extents as the two images with the changed areas highlighted. It's a simplification of course but you get the idea :)

You can try out Opticks. It has a change detection plugin.
