Anime News Network has an article that will be of interest to libraries that purchase manga. Japan is experiencing a paper and ink shortage because of the earthquake and tsunami. Therefore, many manga, newspapers, and magazines are being delayed. This will of course effect the manga industry in translating new material to the international market. Some of your libraries titles might be delayed because of this, but tell your patrons to be patient and understanding (which most will be) of what has happened in Japan. Link below to the full article.
