At this time of year, friends who know about my passion for Civil War history sometimes ask for help in choosing war-related gifts. I'm only too happy to help.

Books

There are a number of new Civil War books out this year, many that have gotten excellent reviews. I surveyed several experts on the war and asked them which book they would recommend if they could choose only one. Here's what they said:

Harold Holzer, a member of the Abraham Lincoln Bicentennial Commission: "Crossroads of Freedom: Antietam," by James M. McPherson. That book also got the votes of Frank J. Williams, another member of the Lincoln Commission, and Ed Smith, a professor at American University.

Ed Bearss, National Park Service historian emeritus: "The Fredericksburg Campaign: Winter War on the Rappahannock," by Francis Augustin O'Reilly.

Edna Greene Medford, Howard University professor: "Race and Reunion: The Civil War in American Memory," by David Blight.

Jean Baker, Goucher College professor: "They Fought Like Demons: Women Soldiers in the Civil War," Deanne Blanton and Lauren Cook.

Gabor Boritt, Gettysburg College professor: "Fredericksburg! Fredericksburg!" by George C. Rable.

Trees

For the enthusiast who is also a tree lover, American Forests has a selection of nine trees with Civil War pedigrees.

Through cuttings, seed propagation and grafts, the choices include an offspring of the Wilderness Kentucky Coffee Tree of the Ellwood Plantation that shades the grave of Confederate Gen. Thomas "Stonewall" Jackson's arm, amputated during the Battle of the Wilderness.

There is also the Antietam Sycamore that survived that battle and the Gettysburg Address Honey Locust, the only tree still surviving at the site of the famous speech.

Each tree comes with a certificate of authenticity that gives the history of the tree and an arboretum tag embossed with the tree's name, species and botanical name.

For more information, call 800-320-8733 or visit the Web site, at www.historictrees.org.

Education

If books or trees don't sound just right, consider giving the gift of knowledge. Each year in July, American University offers the Civil War Institute, an intense five-day course that can be taken for credit. Morning lectures are followed by afternoon bus tours. It is a kind of boot camp for the beginner and an intellectual challenge for the more learned. Call 202-885-1192 or e-mail esmith@american.edu.

Each November, the Lincoln Forum holds a three-day symposium in Gettysburg with an array of excellent speakers addressing Lincoln-related themes. The atmosphere is relaxed, but the subject is taken very seriously. I have attended the past three years and highly recommend it.

The Web site is www.thelincolnforum.org, or e-mail anetwest@earthlink.net.

The bargain on this list of suggested gifts is a membership in the Civil War Preservation Trust, the country's largest nonprofit battlefield-protection organization. Spokesman Jim Campi said there is a holiday special membership for $26. The usual rate is $35. That includes four issues of the trust magazine, "Hallowed Ground," and a blue Preservation Trust baseball cap.
