Hi,

'Scan' has the idea of looking at quite quickly but from top to bottom or from side to side. If you scan a page of text, you are not looking at every single word in detail. You can also scan the sky or the horizon when you are looking for a plane or a bird. 'Scan' is of course used in a technical sense whereby you copy a piece of text or a photograph with a 'scanner', which will then be transferred to a computer.

Hi Sitifan,

In addition to Alan's excellent explanation I'd like to say that the word 'reading' doesn't make much sense in the given context. Maybe it's a typo and the word should read 'reader'. A reader is a book that contains a collection of passages or excerpts of other books.
