Few posts on this blog have received as much response as "Adopting Open Records." The show it complemented, "Report Argues for Open Birth Records," garnered a lot of attention, too. Many of you noted how difficult it is for an American-born adoptee to obtain birth information. On today's program, in the second hour, we'll talk to two persons, born abroad, adopted by Americans, who have tried to find their biological parents — in Korea and Vietnam, respectively. And we'll talk to Jeff Gammage, a staff writer for The Philadelphia Inquirer, who adopted his two daughters from China. All three of them blog for The New York Times, at Relative Choices. After we hear their stories, we'd like to hear yours. Are you a foreign-born adoptee? Have you tried to find track down your biological parents? What are some of the challenges you faced?
