According to Google:-)
” About Google’s regular crawling of the webGoogle’s spiders regularly crawl the web to rebuild our index.

Any number of factors can affect the crawl frequency of individual sites. Our crawl process is algorithmic; computer programs determine which sites to crawl, how often, and how many pages to fetch from each site. We don’t accept payment to crawl a site more frequently. “

This is for regular web pages, but databases are part of the “Deep web” that cannot be crawled like regular webpages (

There are a few ways to get a database indexed in Google, but it’s a certain amount of work and much more than just a regular website where everything just happens by “magic”. I am sure that an organization such as Worldcat has some additional methods as well.

As a footnote, I have noticed that a lot of the bibliographic information that used to be in Google Books–found in the “About this Book” page and I always supposed came from OCLC–is no longer there.
