Blog: The term "weblog" was coined by Jorn Barger on 17 December 1997. Then Peter Merholz, jokingly broke the word weblog into the phrase we blog in the sidebar of his blog in 1999, from where it becomes popular as "blog". Thus Blog is derived from Weblog. Blog or weblog is a web-based publication consisting primarily of periodic articles normally in reverse chronological order with reflections, comments, and often hyperlinks provided by the writer.

1. Definition: Blogs have different meaning to different people, ranging from “online journal” to “easily updated personal website”. A weblog is a journal (or newsletter) that is frequently updated and intended for general public consumption. Blogs generally represent the personality of the author or the Web site.

According to Concept Websites Ltd (, “a blog is basically a journal that is available on the web. The activity of updating a blog is "blogging" and someone who keeps a blog is a "blogger." Blogs are typically updated daily using software that allows people with little or no technical background to update and maintain the blog”.

In simple, it can be said that it is a web based website where articles posted will automatically be arranged in reverse chronological fashion or in a chronological fashion. The owner/member will post message which are sometimes rich with graph, audio, video and hyperlink periodically enabling others to view and comment. Topics often include the owner's/member’s daily life or views on a particular subject or topic of important to the group. The original post with its associated comments and discussion provide a very insight to the topic at hand.

            Many blogs are frequently updated and publicly accessible i.e they allow anybody to sign up at any time; some others are private where entry to the group is restricted. Some advanced users have server-side software, and often implement membership management and password protected areas. Others have created a mix of a blog and wiki, called a bliki.

2. History: At the initial stage of internet development, Usenet, e-mail lists, Bulletin Board Systems (BBS), chronicles, commonplaces, diaries, and perzines were used as a form of Citizen Media. Bulletin Board is a service whereby messages and points of interest can be posted to be read and replied to unlike list server. The news group provides access to thousands of topic based discussion group services which are open to all. The news reader software allows one to post an article to any group for others to read. A comment to the message (original) can be added to the thread of the article. In recent times these are effectively replaced by the “blog”.

During recent days, blog has evolved into a tool that offers some of the most insightful information on the Web. It provides self-publishing phenomenon represented by blogging and becoming much more common in LIS, as librarians, libraries and library associations have begun to blog as a way of communicating with their patrons and constituents. Many librarians world wide also publish their personal blogs that offer a wealth of information about librarianship, their parent institution and sometimes to their personal lives as well.

The emergence of blogging provides a medium to give readers of the library new perspectives on the realities, as well as often offering different viewpoints from those of its official news sources. Many bloggers began to provide nearly-instant commentary on televised events, creating a secondary meaning of the word "blogging": to simultaneously transcribe and editorialize speeches and events shown on television (liveblogging).

3. Anatomy of a Blog Entry: Blog uses web interfaces that allow anyone over the Internet, to create blogs by their own. It usually does not demand the maintenance of server software by the users themselves. It also does not demand to go for the HTML. A blog entry typically consists of the following:

a) Title: The main title, or headline, of the post;

b) Body: Main content of the post;

c) Permalink: The URL of the full, individual article;

d) Post Date: Date and time the post published.

A blog entry optionally also includes the comments or feedback. Comments are a way to provide discussion on blog entries. Readers can leave a comment on a post (a way of correcting one’s error) or they can also leave their personal opinion on the previous post(s).

4. Types: There are various types of blogs, and each differs in the way content is delivered or written. A typical blog combines text, images, and links to other blogs, web pages, and other media related to its topic, the ability to quote another user's post with special formatting in ones post is also a special feature of many blogs. Generally, blog can be categorized as follows:

a) Linklog: A blog comprising links;

b) Moblog: A blog written by a mobile phone or Personal Digital Assistant (PDA);

c) Photoblog: A blog comprising photos;

d) Podcasting: Blog containing audio;

e) Vlog: A blog comprising videos.

Blog can also be categorized based on a particular subject, such as political blogs, travel blogs, legal blogs (often referred to as a blawg), Library blogs, Academic Library blogs, Librarian’s blogs and so on.

5. Importance: Blogging combined the site with tools to make linking to other pages easier specifically permalinks, blogrolls and TrackBacks. This, together with blog search engines enabled bloggers to track the threads that connected them to others with similar interests.

a) Blog as a Forum: The ability for readers to leave comments in an interactive format and the scope for adding more than one author in a blog, can be used to create discussion forum. Wordpress comments at the bottom of a blog post allow for a single-threaded discussion of any given blog post. Slashcode, on the other hand, is far more complicated, allowing fully threaded discussions and incorporating a robust moderation and meta-moderation system as well as many of the profile features available to forum users.

b) Blog as a Group: The Blog’s RSS Feed or Atom by burning with some feed burning services can be used to provide email subscription option (some blog hosting service even produce it by default). This feature can be used as a group to notify the intended users or reader or subscribers about some announcement.

Blog also have blogrolls (i.e. links to other blogs which the owner reads or admires), and indicate the social relationship of a particular blog to those of other bloggers. Pingback (links to other sites that refer to the entry) and trackback (one of three types of Linkbacks, methods for Web authors to request notification when somebody links to one of their documents) allow one blog to notify another blog, creating an inter-blog conversation. In summary, blogs engage readers and build a virtual community around a particular person or interest, which have immense implication in library and information science.

c) A Major Part of the Internet: Blogs are easy to create and maintain as compared to websites. As a result, people are turning towards blog as a publication medium. Day by day, its volume as well as quality increases and now we are in a position where we can say that if one is unable to locate any information over internet by searching in the traditional general purpose search engine then it must be in blog.

d) Latest Information: The literature search forms the backbone of any research activities. In recent times, a part of this business relies on internet and for a comprehensive list of resources over internet, the search should extend to blog also, as it contains the latest, up to the minute information on a given topic.

e) Substitute of Mainstream Media: Blog increasingly considered as a substitute of the mainstream media for news services, consultants, etc. As blog becomes a standard part of the publicity arsenal, it is used extensively as a tool for outreach and opinion forming and as means of applying pressure upon concern authority and like other. It can also be used to push the messages directly to the public by avoiding the filtering process of the mainstream media (the editorial board of which often cut down the massage as a means to avoid the legal liabilities, to present credible news or at times to justify their presence!).

6. Finding a Blog / Blog Search Engine: The general purpose search engines generally avoid displaying results from blogosphere. So, for searching the blog over internet, reliance must be placed on the specially designed blog search engines. Several blog search engines are used to search blog contents (also known as the blogosphere), such as blogdigger, Feedster, and Technorati, which helps one to find out what people are saying on any subject of his/her interest.
