When you create a post on your WordPress blog, you can file that post under a category that you specify. This feature makes for a nifty archiving system in which you and your readers can find articles/posts that you’ve placed within a specific category. Articles you post are also sorted and organized by date (day/month/year) so that you can easily locate articles that you posted at a certain time.
You can easily create an archive listing by using a WordPress plugin called Clean Archives Reloaded, which you can find in the WordPress Plugin Directory. This plugin is easy to install, and to use it, you just need to create a page and add a short code segment ([cleanarchivesreloaded]) to the page content; that code automatically builds a Chronological Archives page that links to all the content you’ve published on your site.
The different types of archives and content include
Categories: Create categories of topics in which you can file your articles so that you can easily archive relevant topics. Many websites display content by category — typically referred to as a magazine theme, in which all content is displayed by topic, rather than in a simple chronological listing.
Tags: Tagging your posts with micro keywords, called tags, further defines related content within your site, which can improve your site for SEO purposes by assisting the search engines in finding related and relevant content. You can also provide additional navigation to help your readers find relevant content on your site.
Date Based: Your content is automatically archived by date based on the day, month, year, and time of day you publish it.
Author: Content is automatically archived by author based on the author of the post and/or page — you can create an author archive if your site has multiple content contributors.
Keyword (or Search): WordPress has a built-in search function that allows you and your readers to search for keywords, which presents an archive listing of content that’s relevant to your chosen keywords.
Custom Post Types: You can build custom post types based on the kind of content your site offers — you can find detailed information on custom post.
Attachments: WordPress has a built-in media library where you can upload different media files such as photos, images, documents, videos, and audio files (to name a few). You can build an archive of those files to create things such as photo galleries, eBook archives (PDFs), or video galleries.
Links: Build your own link directory of resources by using the built-in Link Manager in the WordPress Dashboard, and then create a page to display the links on your site.
