Google is adding back issues of magazines to its Book Search index. From the Official Google Blog:
Try queries like [obama keynote convention], [hollywood brat pack] or [world’s most challenging crossword] and you’ll find magazine articles alongside books results. Magazine articles are tagged with the keyword “Magazine” on the search snippet.
Over time, as we scan more articles, you’ll see more and more magazines appear in Google Book Search results. Eventually, we’ll also begin blending magazine results into our main Google.com search results, so you may begin finding magazines you didn’t even know you were looking for. For now you can restrict your search to magazines we’ve scanned by trying an advanced search.
The Associated Press says Google will share advertising revenue generated by Google ads with magazine publishers. Embedded advertising from the original print editions remains intact as part of the overall archive. It’ll be interesting to see how Google and magazine publishers coordinate on ads if/when publishers seed current editions into the service.
