Any time you need to research something you have archives. Archives are designed to give you past information whether it is newspaper articles, job postings or blogs. When you are on a website there will be a couple of different types of archives. Blogs are just one archive you might want to search. You can look back through the archives to find out what information has been shared by a company since it began. Any articles posted on the site will also be archived based on what type of article they are.

For instance news is often in archives. The news offered may relate to company news or be news relating to a topic about what the site sells. Archives are needed on a website for navigation.
