Searchengineland.com mentions the query "book of revelation", which shows the timeline results pictured above at the bottom of the first page.

One can also view the timeline on queries like -thomas jefferson- and -albert einstein-.

According to News Archive Search Help by Google:

News archive search provides an easy way to search and explore historical archives. Users can search for events, people or ideas and see how they have been described over time. In addition to searching for the most relevant articles for their query, users can also see a historical overview of the results by browsing an automatically generated timeline.

Search results include content from a number of sources, including both partner content digitized by Google through our News Archive Partner Program and online archival materials that weve crawled. Search results can include content that is freely accessible as well as content that requires a fee. Articles related to a single story within a given time period are grouped together to allow users to see a broad perspective on the topics they are searching.

So as far as these examples are concerned, it is seen that the new timeline display shows up in addition to the results that appear on the main search page, and often appears along with news, image, or book results, too.
