 January 2013 (UTC)  :Hello, and thank you for your interest in Wikipedia. Normally we don't give detailed answers to general questions on this page, which is designated for questions and comments about the ClueBots (a set of programs that perform automated actions). However, since you asked, I'll give you a quick response here and I've left some links to more detailed information at . Displaying the article title in bold in the first sentence is part of an effort to standardize the format of Wikipedia articles, which is defined in the Manual of Style. The authority control information is a way to link Wikipedia articles to various library catalogue systems. (You can click on the links in this paragraph for more information.) –   04:16, 17
