Sometimes it seems to me that old-ish reference books (on not too-hard science) age into cinematographic world-building. For example, there are some good volumes on the vegetation structure of European forests c. 1950-s. As botanic material, they are dated: the woods have burnt, grown, got paved, incorporated alien species etc., and the current methods to describe vegetation are more demanding.
Yet as simple pictures of the state of the world, grainy and washed out in places, they are good enough.
