Archive-It

From the Learn more page:

The Internet Archive's new subscription service, Archive-it, allows any user to create, manage and search their own web archive through a web interface without any technical expertise required. Archive-it can be used to archive an institution's own web site, or build collections of up to one hundred web sites.

Through a web based interface users can create web collections, catalogue the websites associated with a collection, archive websites in the collection, monitor the archiving process, search and browse the collection when complete, and administer access to these collections. In addition, the service will support collaborative collections, where curators at separate organizations can create and share collections.
