After August 2008 sites had to be listed on the Open Directory in order to be included. According to Jeff Kaplan of the Internet Archive in November 2010, other sites were still being archived, but more recent captures would become visible only after the next major indexing, an infrequent operation.

Who stated that sites not on Open Directory were still being saved but would not be released until the Archive was reindexed?
