Coming to me on Twitter via Rudibrarian is this piece from Wired about a U.S. funded search engine out of Johns Hopkins called Popline that is, apparently, blocking any search that uses the term "abortion".
A U.S. government-funded medical information site that bills itself as the world's largest database on reproductive health has quietly begun to block searches on the word "abortion," concealing nearly 25,000 search results.
Called Popline, the search site is run by the Johns Hopkins Bloomberg School of Public Health in Maryland. It's funded by the U.S. Agency for International Development, or USAID, the federal office in charge of providing foreign aid, including health care funding, to developing nations.
The massive database indexes a broad range of reproductive health literature, including titles like "Previous abortion and the risk of low birth weight and preterm births," and "Abortion in the United States: Incidence and access to services, 2005."

Edit: LISNews reports that Popline has now "unlocked abortion search".
4/5 Edit: More info and how a librarian discovered it all on LISNews.
