explosivejared writes "The Washington Post is running a story on the fight between publishers and search engines over just what exactly is allowed to be shown by search results. From the article: 'The desire for greater control over how search engines index and display Web sites is driving an effort launched yesterday by leading news organizations and other publishers to revise a 13-year-old technology for restricting access. Currently, Google, Yahoo and other top search companies voluntarily respect a Web site's wishes as declared in a text file known as robots.txt, which a search engine's indexing software, called a crawler, knows to look for on a site ... [new] proposed extensions, known as Automated Content Access Protocol, partly grew out of those disputes. Leading the ACAP effort were groups representing publishers of newspapers, magazines, online databases, books and journals. The AP is one of dozens of organizations that have joined ACAP."
