As someone almost said there are lies, damned lies and Key Scottish Environment Statistics (essential for sustainable development). The last of these are not of course lies, damned or otherwise, but a useful Scottish Government compendium of information on a wide range of environmental topics, with an emphasis on trends over time. This is the tenth edition (and the first sadly to be available web-only) of this extremely useful, formerly pocket-sized (but now of no size at all in its digital manifestation) publication.
