Sentence:  In Poland, some <WSD>samizdats</WSD> are different: they are professionally produced and are sold for money. But the money that these Polish consumers pay for these illegal <WSD>samizdats</WSD> is not dissipated in the domain of individual or corporate profits, nor does it help support the government and its publishing monopoly. The money acquired through sales is used for – and this the consumer is well aware of – the advancement of the Solidarity movement. 
Meaning of the word marked with <WSD> tags:  A samizdat publication.
