I've been in towns where there is no library, or where the library for the high school and the library for the town is one room, and it's smaller than my modest living room here. So you don't have many resources in 1950 or even 1970. This is the year, 2013, every town in America is connected to the web. Every town in America is therefore connected to all kinds of resources at the Library of Congress, at 100,000 websites.

Textbooks should show that neither morality nor immorality can simply be conferred upon us by history. Merely being part of the United States, without regard to our own acts and ideas, does not make us moral or immoral beings. History is more complicated than that.

The world, of course, doesn't come divided into disciplines. The world just is.

Teachers need to teach the subject rather than to teach the textbook.

All of the common core standards stuff about critical reading and critical thinking and so on can only be positive.

Conclusions are not always pleasant.

I think the first important thing is that usually most textbooks are not written by their authors. And so by author I mean the people who did not write them; so it's a new definition of "author."
