By automatically stripping out results unrelated to medical imaging, Yottalook vastly increases the utility of the various specialized search services that you may already be familiar with in Google. For example, Google Book Search allows you to search within the actual text of an enormous number of hard-copy books, both recent and out of print. The digitized copy of the book appears onscreen opened to the page of interest, with your search terms already marked in yellow highlighting. The preview mode allows you to jump between chapters or flip page by page through surprisingly extensive sections of each book. Yottalook optimizes this already impressive service by listing only radiology texts in the search results. A search for “glioblastoma” is thus reduced from an overwhelming 1306 books in the native Google Book Search, including numerous patient survival guides and basic science texts, to a more manageable 168 medical imaging texts in Yottalook Books (Fig 3). Similarly, when one searches in the Yottalook customization of Google Scholar, one's results are already prefiltered to include only the imaging literature.
Yottalinks” are special sites that the Yottalook editors have designated as particularly high yield for particular radiology search topics. For example, if one queries “renal failure,” a Yottalink to an online glomerular filtration rate (GFR) calculator appears in a separate section of the results page.

There are numerous additional features to be discovered on the Web site. After using it just a few times, I believe that many radiologists will opt to make Yottalook their first-line search rather than Google or other general search engines.

There are several ways of making access to Yottalook's search results even easier. One can make Yottalook the Web browser's default homepage, add a Yottalook button to the Google search toolbar, or incorporate it into one's own customized Google “mash-up” homepage (iGoogle). Yottalook will be showing up in other contexts as well, since it is available for developers to include in their own Web sites and has already been integrated as the search engine of the RSNA Web site (http://www.rsna.org).
