The Library of Congress’ American Memory has constructed an interactive database containing over 3,000 maps from the Civil War era. The collection offers detailed descriptions of a variety of topics such as Union General William Tecumseh Sherman’s successful Atlanta Campaign to an outline of 23 forts defending the Confederate capital of Richmond, Virginia. Another great tool within the database is the fact that each map contains a list of subject links that help to expand upon your research. The collection contains map collections originally owned by both Union and Confederate military authorities.

American Memory has other databases that can prove useful in your research. Civil War railroad maps show an intricate description of the development of railroads through 1900.  There is also a collection of over 1,000 photographs from the Civil War era that have been specifically selected due to their innate detail.

The University of Richmond Digital Scholarship Lab’s “Voting America” is great resource on US Presidential elections. The site provides a series of maps on each election between 1840 and 2004  that show a variety of different information. For example, the 1860 election map includes layers that breakdown the popular vote by county and counties with small margins of victories (when a second place candidate lost by less than 10 percent of the vote). The site also organizes the maps by topic, such as turnout and third party voting. In addition, this interactive map allows you to select the election data that appears. Also, be sure to check out all of the videos – including this one with Professor Edward Ayers who discusses the elections before the Civil War.

Though previously mentioned in another post, the The Valley of the Shadow Project has a wide range of primary sources from newspapers, maps, letters, and statistics all available for use in the 7-12 classroom. Broken up chronologically into three periods, the Project archives two communities (Augusta County, Virginia and Franklin County, Pennsylvania) between the years of 1859 and 1870. A particularly good lesson plan by Alice Carter compares the impact and the development of the railroads in both counties using various articles from historical newspapers. The lesson provides a teacher with preselected articles, however, one may choose to either find newspaper accounts that reflect individual class interests or allow students to search for their own, using the newspaper indexes. One special note: teachers could extend the lesson and explore the impact of railroads during reconstruction.

Among the many websites and digital projects bringing the 19th century to the World Wide Web is the Lincoln Archives Digital Project from researcher Karen Needles. This ambitious project began in 2002 with the goal of digitizing all federal records from the Lincoln administration, including every cabinet and every agency. The project is the first of its kind to digitize the holdings of an entire administration and its standards are high. The project uses high resolution scans of original documents from the National Archives and incorporates technology such as “Zoomify” to create a high quality and easily accessible collection.

The project is not limited to just federal documents and includes maps, newspapers, photographs, political cartoons, blogs, lesson plans and even a dictionary and who’s who of the period. The wealth of information is seemingly endless and is always growing, although a subscription is required for full access to the project. For more information, check out the project and the August article about it in Civil War News.

Interested in all things Lincoln?  The city of Ottawa, Illinois’ webpage houses a pdf entitled The OttawaLincoln Knew.  This file pulls most of its information from Aletia Tisler’s book, “Lincoln was Here,” using only facts and anecdotes pertinent to the town of Ottawa.  Although the section focuses mainly upon the Lincoln-Douglas debate that took place there in 1858, it also showcases Lincoln’s first meeting with Douglas in the courtroom.  At the bottom of the file, the site includes a map of modern day Illinois with location markers that specify places made famous by Lincoln’s presence.  This site would be especially helpful for someone trying to create a unique family vacation seeped in history.

The Northern University of Illinois page, The Lincoln/Douglas Debates of 1858, offers wide-ranging coverage of the historic oratory campaign. The site houses numerous primary documents including debate transcripts, maps, and contemporary press coverage. Also, The Lincoln/Douglas Debates of 1858 provides a video podcast on the debates by Columbia’s Eric Foner as well as lessons plans for teachers that include brief descriptions of the debate topics and guided reading assignments for students. This site would be a great addition to any history teacher’s repertoire of resources.

The National Park Service is looking to expand upon its Underground Railroad stops in its National Register of National Historic Places.  By visiting , “Aboard the Underground Railroad: A National Register Travel Itinerary” you can help the NPS. At the website, one can explore stops on the Underground Railroad, both in the North and South, and even a few stops in the territories. The site is also useful in offering a “Learn More” page, , where additional sources regarding the Underground Railroad can be found, including web resources.

With your help, by applying to the National Register of Historic Places to add your historic Underground Railroad site, this website and tool can only grow and become more useful.

One of the better resources on the website for the Civil War Preservation Trust are the very interesting, informative, and entertaining animated battle maps. Rather than just show the course of a battle through static maps, these flash-based animations such as Fredericksburg and Chancellorsville show highly detailed troop movements while providing all the information necessary to explain the battles. These maps are very useful for visually understanding the course of a battle.

Other maps include Chantilly, Cedar Creek, and Bentonville. All are worth a look.

The US Army has released a flash-based, interactive look at the Battle of Gettysburg . The page includes a step-by-step depiction of the battle using a topographic map with graphic overlays of the various Confederate and Union forces. Also included are profiles of various participants, weapon analysis, and other statistics. The website has plenty of valuable and interesting information. It requires Adobe Flash Player in order to run.

History teachers should check out Northern Illinois University’s digital collections. While some collections focus only on Illinois history, others cover a broad range of topics such as the Mexican-American War and election campaigns (1840 – 1860). Each site offers primary sources, maps, lesson plans, audio files, and other materials. Be sure to take a look at Mark Twain’s Mississippi for a number of interesting resources, such as large collection of videos. In addition, Northern Illinois University provides free access to articles published in the Journal of the Illinois State Historical Society between 1979 and 2006.
