If "blog" is a term that's new to you, don't be concerned. You've probably encountered lots of blogs while using the Web for work or recreation. In fact, blogs existed long before the term was coined. NCSA's What's New page from back in June 1993 is credited as being one of the earliest blogs. In the library sphere, Jenny Levine's Librarians' Site du Jour is considered the original library blog.
Blog, short for Weblog, is a Web site that contains brief entries arranged in reverse chronological order. Blogs are diverse, ranging from personal diaries to news sites that monitor developments on anything from Outer Mongolia to copyright law. Evan Williams, the creator of Blogger, describes them this way: "the blog concept is about three things: Frequency, Brevity and Personality."
In order to get a feel for the world of blogging, it helps to get a handle on the lingo. "Blogging" is the act of creating a blog. A "blogger" is a person who maintains a blog. Bloggers create entries, which they "post" or publish to their blog. "Bloggrolling" is the act of moving from one blog to another.
A blog can be created by just one author or done collaboratively by a community of authors. Blogs can be updated from several times per day to just a few times per week or month. Some blogs encourage interactivity between the writer and audience by allowing readers to post comments and questions about entries.
Today, blogs range from the simple "what's new" type of listing to sophisticated Web sites with dozens of bells and whistlesâ€”site search capabilities; topical categories; daily, weekly, and monthly archives; built-in mailing list management functions; and RSS headline syndication. The blog content ranges from the interesting and insightful to the mundane and useless.
