Books containing swear words should be sold in plain covers displaying warnings, just like pornography, a top Russian lawmaker has said.
"We should consider selling such literature in cellophane covers like pornographic publications, with the warning -- Caution - uncensored language," said Stanislav Govorukhin, head of the Russian parliament's committee on culture.
Govorukhin is also a film director and member of the ruling United Russia party.
President Vladimir Putin recently signed on a law making the use of obscene language by media outlets punishable by fines.
The law sets fines of up to $6,300 for media outlets allowing the use of swear words and fines of around $100 for individuals, with provisions for the confiscation of equipment.
The law, which also applies to internet-only media, was previously approved by both houses of parliament.
The Kremlin has said that the decision on what exactly constitutes a swearword or obscene language will be taken by linguistics experts.
