On April 22, the Douglas County Libraries invited our volunteers to a modest recognition dinner. The occasion: looking back on 2008 library volunteerism. It was a record-breaker.

For our 25th wedding anniversary, I gave my wife a framed version of a beautiful photograph she took of a pond in Berlin.

She asked what I wanted. I said I wanted to have my DNA tested. After 25 years, I said, you deserve to know who I am.

So she ordered the testing kit from National Geographic's Genographic Project (see www.nationalgeographic.com/genographic), and I dutifully swabbed the inside of my cheeks with the scraper. It will be some four to six weeks before I hear back. It cost about $100.

So those rumors about Indian ancestry -- truth or myth? Are there any other surprises? I chose to follow the paternal line (my paternal grandmother's father was supposed to be full-blooded Cherokee).

National Geographic also sent a quite wonderful DVD about the genetic history of the human race. Dr. Spencer Wells is a most engaging host, who gallivants around the globe exploring and explaining human genetic change.

Here's the broad thesis of modern genetics: we are all Africans.

I want to tell you about a magical book. It's a book that tells several stories at once, filled with tragedy and humor and love. It does this utterly without words.

The book is called The Arrival, by Shaun Tan. It is, technically, a "graphic novel" -- a sort of hardbound comic book.

The cover looks like a worn leather folio, with a drawing of a man encountering some kind of bizarre animal. Just inside the covers is another arresting image: 60 faces, of every ethnicity.

The story begins in what I think of as "the old country." A man is packing up a photograph of his small family. Soon, we see them all walking through the city. Around them there are shadows: the tails of dragons, snaking through the gray streets.

The man boards a train, pulling away from the fingers of his wife and daughter.

Soon he is on a ship, along with many other emigrants. For several pages, we see nothing but clouds. Finally, he arrives to a country that is utterly bewildering. There is a big harbor, with statues in the water. There is an enormous hall.

The numbers tell the story. Some 80 million Baby Boomers were born; 40 million Gen-Xers.

A 2004 report from Colorado's Library Research Service made several predictions:

* More than 20 percent of responding Colorado librarians expect to retire within the next five years. Of all responding school librarians, about half indicate plans to retire within five years; more than three times the proportion for public librarians and almost five times the proportion for academic librarians.

* Many librarians who responded to this survey are not waiting until age 65 to retire. Almost 30 percent of those who expect to retire within the next five years are ages 45 to 54.

* Retiring librarians will take with them substantial administrative skills. Of these prospective retirees, one out of five expects their job to be combined with another or eliminated. Almost one out of five expects to be succeeded by someone with less education.
