In the context of the World Wide Web, a bookmark is a Uniform Resource Identifier (URI) that is stored for later retrieval in any of various storage formats. All modern web browsers include bookmark features. Bookmarks are called favorites or Internet shortcuts in Internet Explorer, and by virtue of that browser's large market share, these terms have been synonymous with ''bookmark'' since the first browser war. Bookmarks are normally accessed through a menu in the user's web browser, and folders are commonly used for organization. In addition to bookmarking methods within most browsers, many external applications offer bookmark management. Bookmarks have been incorporated in browsers since the Mosaic browser in 1993.〔("New X-based information systems browser available." ), post to ''comp.infosystems'' by Marc Andreessen on February 16, 1993〕 Bookmark lists were called ''Hotlists'' in Mosaic〔("May World-Wide Web News" ) in 1993 by Tim Berners-Lee〕 and in previous versions of Opera; this term has faded from common use. Other early web browsers such as ViolaWWW and Cello also had bookmarking features. With the advent of social bookmarking, shared bookmarks have become a means for users sharing similar interests to pool web resources, or to store their bookmarks in such a way that they are not tied to one specific computer or browser. Web-based bookmarking services let users save bookmarks on a remote web server, accessible from anywhere. Newer browsers have expanded the "bookmark" feature to include variations on the concept of saving links. Mozilla Firefox introduced live bookmarks in 2004,〔("Mozilla Foundation Releases the Highly Anticipated Mozilla Firefox 1.0 Web Browser" ), press release on November 9, 2004〕 which resemble standard bookmarks but contain a list of links to recent articles supplied by a news site or weblog, which is regularly updated via RSS feeds. "Bookmarklets" are JavaScript programs stored as bookmarks that can be clicked to perform a function. ==Storage== Each browser has a built-in tool for managing the list of bookmarks. The list storage method varies, depending on the browser, its version, and the operating system on which it runs. Netscape-derived browsers store bookmarks in the single HTML-coded file ''bookmarks.html''. This approach permits publication and printing of a categorized and indented catalog, and works across platforms. Bookmark names need not be unique. Editing this file outside its native browser requires editing HTML. Firefox 3 stores bookmarks, history, cookies, and preferences in a transactionally secure database format (SQLite). Internet Explorer's "Favorites" (also "Internet Shortcuts") are stored as individual files named with the original link name, and the filename extension ".URL", for example "Home Page.URL" collected in a directory named "Favorites" which may have subdirectories. Bookmark names must be unique within a folder. Each file contains the original URL and Microsoft-specific metadata. Browsers have varying abilities to import and export bookmarks to favorites, and vice versa. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bookmark (World Wide Web)」の詳細全文を読む スポンサード リンク
