Best Web Archive

Web Archive is a great tool. You could check how a website looked before and what difference it make. For webmaster and domainer its a great tool.

The Web changes constantly, and sometimes that page that had just the information you needed yesterday (or last month or two years ago) is not available today. At other times you may want to see how a page’s content or design has changed. There are several sources for finding Web pages as they used to exist.

While Google’s cache is probably the best known, the others are important alternatives that may have pages not available at Google or the Wayback Machine plus they may have an archived page from a different date. The table below notes the name of the service, the way to find the archived page, and some notes that should give some idea as to how old a page the archive may contain.

Multiple copies of pages
Wayback Machine	Enter URL in search box to view	From late 1996 to 8-14 months ago; from the Internet Archive. Often includes cached images, CSS, and JavaScript.
Archive-It Collections	Full-text search or enter URL	Highly selective collections, primarily of state agencies and organizations. Some general pages included as well. Full-text searching. Use “Search All Collections” for broadest coverage. Multiple dates. Images, PDFs, text.
WebCite	Enter URL in search box to view	Launched in late 2005, this site only archives Web pages cited in certain journal articles (mosty health-related). Multiple dates may be available via drop down box in upper right. No text search access. Text, images, PDFs cached. Examples: Web page, newspaper article, PDF.

ZoomInfo	[Cached] link	Only in people search, associated pages have cached links. Cache date given, but no searchable or URL access. You have to know what person might be on a specific page.

Note that none of these include all Web pages. A robots.txt file or a <meta name=”ROBOTS” content=”NOINDEX”> in the header of a file can prohibit the crawling of the page. Google and other should look for a <meta name=”ROBOTS” content=”NOARCHIVE”> in the header and not cache such pages. But the exclusions do not always work. Other possible ways to resurrect a dead link include checking in your local browser’s cache if you visited the page recently or hope that someone else copied and posted the file on the Web.
