An online collection or website catalog is a web directory or connection directy. That is, it is a World Wide Web directory of (all or part of) the World Wide Web.Historically, directories and their contact details usually listed entries for persons or companies; such directories are still in use today.
A web directory comprises website entries, including links to certain websites, grouped into categories and subcategories. In addition to a link, each entry can include a website title and a summary of the contents of the website.
The entries in most web directories are for entire websites, instead of individual pages inside them (called “deep links”). Inclusion in just a few groups is also restricted to blogs.
There are two ways on the Web to find information: by surfing or scanning. In an organized list, web folders have connections to make searching smoother. By providing a search engine to search the archive, several web directories merge scanning and browsing.
Most web directories are manually created by human editors, unlike search engines that base searches on a database of entries automatically compiled by web crawlers. Many web directories encourage site owners to submit fitness submissions for inclusion on their site, and have editors review submissions.
Online directories may have a broad variety, or they may be limited to individual subjects or areas.
Entries can be listed free of charge or by paying entries (meaning the site owner must pay to have his or her website listed).
RSS folders are identical to web directories, but instead of web site links, they contain sets of RSS feeds.
