ANTHOLOGIES PRODUCED AS A FREELANCE EDITOR
The following anthologies of articles from various sources were textbooks
sold to schools and libraries, which I compiled to the publisher's specifications.
I wrote only their introductory essays. The aim was to offer an unbiased
presentation of both sides of controversial issues, so they do not reveal my
own views on these subjects.
