长期以来,差不多所有报纸杂志均规定作者不得“一稿两投”,个别报刊甚至对一稿两投的作者进行公开批评,扣以各种“帽子”。这种规定和作法是正确的吗?有利于新闻的传播和文艺的繁荣吗? For a long time, almost all newspapers and magazines have stipulated that authors should not “cast a draft for one manuscript.” Some newspapers even openly criticized the authors of the two manuscripts and labeled “hats.” Is this provision and practice correct? Is it conducive to the dissemination of news and the prosperity of literature and art?
