Another Genealogy Book

A few days ago I went to my local library, and it was still holding a book sale. At that book sale I found another genealogy book. I haven't read the book yet, but I think it would still be very useful. The book is Guide to Genealogical Research in the National Archives by the National Archives Trust Fund Board (National Archives And Records Service: Washington D.C., 1982). There maybe a more recent version, but I'm not completely sure. This book has several pictures in it. Given its date, other libraries probably have copies of this book.
