Thanks to the many people who sent me ideas for historical material to discuss on my NYT columns. There were many I couldn't use, but in two cases, I was able to suggest how the researcher could do his or her own op ed on the topic. One of those has been published and another is in the works. Meanwhile I will have my first guest column in this Sunday's NYT and was able to work in some material from Susan Matt's recent book on Homesickness.
