In 1912, Japan presented Washington, DC, with 3,000 cherry trees as a gift. This Library of Congress exhibit uses primary sources to explore the history of the trees, the National Cherry Blossom Festival that grew up around them, and Japan/U.S. relations.

Primary sources are divided up by four themes. "Art and Documentation" includes three sources: a letter from Tokyo mayor Yei Theodora Ozaki to First Lady Helen Taft on the gift of the trees, a memo on artwork acquired by botanist Walter Tennyson Swingle in Japan, and a photograph of Swingle and Seisaku Funatsu, one of the group of Japanese experts who cultivated the trees gifted to the U.S.

In "A Special Gift to Washington from the City of Tokyo," visitors can view Swingle's collection of 11 Japanese watercolors depicting different types of cherry trees.

"Cherry Blossoms in Japanese Cultural History" collects 15 pieces of Japanese artwork depicting traditional hanami (flower viewing), as well as two pieces of Western artwork showing Japanese influence. Also included in this section are 12 stereographs of Japan during cherry blossom time, created between 1904 and 1908 for Western audiences.

"Enduring Symbols of Friendship" includes nine sources exploring the place of the cherry trees in Japan/U.S. relations. A 1938 Japanese magazine cover, notes for a 1934 speech by Japanese ambassador Hiroshi Satou, and a photo of children from the Japanese Embassy at the Tidal Basin show pre-World War II peace. Two political cartoons show how quickly the trees became a symbol of DC, and a photograph shows U.S. cherry blossom viewers during World War II. The section also features three photographs from a 2011 photography contest associated with the National Cherry Blossom Festival.

Visitors can also click on "Exhibition Items" to view all 55 primary sources, sortable alphabetically or by theme.

Some sources lack annotations, and existing annotations are sparse. However, this is a unique collection of sources that could be used as jumping-off points for exploring cultural exchange, international relations over time, and DC history.

The White House Historical Association works "to enhance the understanding, appreciation and enjoyment of the White House." The website has a number of useful educational resources if you know where to look.

Start with the Themes and Media page that gathers educational resources from the entire website into thematic categories from African American history to protests. Within each collection, you'll find relevant selections from the website's pool of 10 text timelines, more than 15 online exhibits and tours, and more than 20 lesson plans labeled by grade level. One exhibit covers the political symbolism of, and national reaction to, First Lady Lou Hoover's invitation of Jessie DePriest, wife of the first African American elected to Congress in the 20th century, to tea.

The History page gathers the majority of these resources in one location. From information on artwork in the White House to milestones in White House staff history to White House pets, there's plenty to discover.

Most of the content in the Classroom section overlaps with that in History. However, here you can access all available lesson plans, sorted by grade level (K–3, 4–8, 9–12), as well as more than 10 primary sources. Finally, this is the place to go for more information on touring the White House or reserving a program for your DC Metro-area classroom.

Memoirs v. Tapes consists primarily of a web-published essay on the Nixon White House Tapes from between October 1972 and February 1973. These tapes were released from the Nixon Library as recently as 2008 through 2010, making them quite new to the public. As a text-heavy resource, and in consideration of the complexity of the questions the content raises, it is likely best used with high school students.

The essay is divided into seven sections and an accompanying appendix. The key issue under discussion is the position of Nixon and Kissinger on the 1972 Christmas bombing of North Vietnam. Nixon's memoirs state that he only reluctantly agreed to Kissinger's eagerness to bomb North Vietnam. In contrast, Kissinger notes that while he was pro-bombing, Nixon generally agreed with him, rather than only coming to the decision at a point of supposed necessity. Most sections of the website are accompanied by audio clips of the actual decision-making conversations; maps; documents such as letters, address drafts, and cables; and video clips.

The Nixon Presidential Library and Museum recognizes that the audio clips can be difficult to understand. As a result, they have prepared a short list of tips to help listeners get the most from the sources. In addition, each audio clip has an accompanying log link. The log lists, in bullet form, the topics of conversation covered in the clip.

The conclusion offers a set of five questions to consider after having perused the site and its resources. The questions, such as "What role did the convening of a new Congress play in December 1972 decisions about ending the war?," are, as noted previously, likely most appropriate for high school classrooms. However, it is possible that they may also be of use in middle school, depending on the engagement and ability levels of students.

Finally, the appendix offers suggested readings, as well as additional documents, audio and video clips, and photographs which may be of interest.
