Thabloids are unsorted, contain duplicates
Thabloids are sorted semi-randomly, i.e. not chronologically. For instance, two Thabloids from 2010 and 1998 are in between the 2015 Thabloids.
Also, there are some duplicate Thabloids, where two different issues contain the same Thabloid. Two examples are 2005/2006 issues 2 and 4, and 2005/2006 issues 1 and 3.
