WebCite is a user directed citation tool that allows you to create a static single page snapshot for your online citations. The service is non-profit and has been operational for 10 years, and it’s been used by hundreds of journalists, writers, historians, bloggers and researchers, in personal, professional and academic capacities. Wikipedia relies on WebCite to prevent “link rot”, and fans have used WebCite on (for instance) Fanlore while documenting fannish history. The service can’t access private, locked or password protected content, and it honors “no indexing” commands. In this, it works much like the Internet Archive/WayBack Machine. Unlike with the Internet Archive, though, you can direct WebCite to a specific page at once instead of hoping that one day the Internet Archive will find and crawl the site.

WebCite needs to raise development funds, or they’ll have to stop offering citation services at the end of 2013. Their fundraising page is here: fundrazr.com/campaigns/aQMp7
