Every **SYN corpus** contains all the [[en:pojmy:synchronni|synchronic]] [[en:pojmy:psany|written]] corpora of the [[en:cnk:syn|SYN]] series published up until the time of the given version's publication. The corpus SYN version 3 therefore contains the corpora  [[en:cnk:syn2000|SYN2000]], [[en:cnk:syn2005|SYN2005]], [[en:cnk:syn2006pub|SYN2006PUB]], [[en:cnk:syn2009pub|SYN2009PUB]], [[en:cnk:syn2010|SYN2010]] and [[en:cnk:syn2013pub|SYN2013PUB]].

Because all of these corpora are **disjunctive** (i.e. they do not contain the same texts), the total size of the SYN version 3 is given by their sum, which makes 2,232 billion words ([[en:pojmy:token|tokens]] without punctuation). The SYN corpus is not  [[en:pojmy:reprezentativnost|representative]]; the dominant component is journalism, which is the result of the predominance of journalistic corpora [[en:cnk:syn2006pub|SYN2006PUB]], [[en:cnk:syn2009pub|SYN2009PUB]] and [[en:cnk:syn2013pub|SYN2013PUB]].

The SYN version 3 corpus is [[en:pojmy:referencni|referential]],and will remain accessible to users even after newer versions have been published. It is however necessary to keep in mind that the linguistic information will become outdated, as a natural result of the referential nature of the corpus.

The composition of the journalistic part of the corpus SYN version 3 covers the production of most of the national daily newspapers (Mladá fronta DNES, Lidové noviny, Právo, Hospodářské noviny, Blesk) and non-specialized magazines (Reflex, Respekt, Týden) between the years 1998--2009. A table containing the 15 titles most represented in the journalistic part of the corpus SYN version 3 (with a layout for the individual years; the numbers are in millions of words, i.e. positions not counting punctuation) can be downloaded below, a preview of the composition of the journalism part can be seen on the following graph.
