WebCite is an on-demand archiving service, designed to digitally preserve scientific and educationally important material on the web by making snapshots of Internet contents as they existed at the time when a blogger, or a scholar or a Wikipedia editor cited or quoted from it. The preservation service enables verifiability of claims supported by the cited sources even when the original web pages are being revised, removed, or disappear for other reasons, an effect known as link rot. ==Comparison to other services== The service differs from the short time Google Cache copies by having indefinite archiving, and WebCite also offers on-the-fly archiving. The Internet Archive, since 2013,〔''(Fixing Broken Links on the Internet )'', Internet Archive blog, October 25, 2013.〕 also offers immediate archiving, however, WebCite has some advantages: * pages cached by WebCite also capture several layers of underlying links while Internet Archive only captures the top page chosen for archiving. The accuracy with which formatting and functionality is preserved also varies greatly between Internet Archive and WebCite. * WebCite checks robots.txt only at the time of archiving, Internet Archive checks robots.txt occasionally so changes in robots.txt (which can be caused by change the ownership of the domain name) can result in removing the cached pages from the Internet Archive. WebCite is a non-profit consortium supported by publishers and editors, and it can be used by individuals without charge. Rather than relying on a web crawler which archives pages in a "random" fashion, authors who want to cite web pages in a scholarly article can initiate the archiving process. They then cite – instead of or in addition to the original URL – the snapshot address archived by WebCite, with an identifier that specifies the cited source. It can be used to preserve cited Internet content, such as the archived web pages through WebCite, in addition to citing the original URL of the Internet content. All types of web content, including HTML web pages, PDF files, style sheets, JavaScript and digital images can be preserved. It also archives metadata about the collected resources such as access time, MIME type, and content length. 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「webcite」の詳細全文を読む スポンサード リンク
