Exactly one decade from the events of September 11, 2001, a new memorial is slated to open at Ground Zero. The memorial website offers the expected information on visiting the memorial, as well as a wealth of information which can be of use well outside of the state of New York.

Plan Your Visit is the place to go if you are considering visiting the memorial yourself or taking a class to the site. Note that there are restrictions on items and bag sizes permitted, that the site contains no public restrooms, and reservations are required with the number of group visits per day limited. Prior to the official opening, visitors can view a preview museum, which includes a StoryCorps recording booth for sharing your own 9/11 story. However, there is still a hefty amount of information here for "digital only" visitors. For example, you can read about how names will be grouped on the memorial—by location at the time of the incident, by company affiliation, and by relationships requested by next-of-kin. What does this system say about how we define ourselves today with and against other people and organizations?

In the same section, you can also find a link to a free iPhone 9/11 history application. This app provides images, a timeline, and a tour of the World Trade Center area. The tour can be used to guide an actual walk, or it can be accessed from elsewhere to explore digitally.

About the Memorial provides an overview of the memorial's design and the reasoning behind these artistic and practical choices. This can be used to get your students to question the purpose of memorials and/or how environmental designs can codify collective experience and relate to the values of their time. One simple example is the use of natural elements—trees and water—in this memorial. How do these choices relate to concepts of healing, Romanticism, sustainability, etc.

Collections includes a variety of potentially useful subpages which present a smattering of 9/11 stories with artifact images and links to oral histories, as well as a small list of international tribute projects. The subsection "Contribute" also allows you or your students to upload reaction artwork, photos, videos, or stories.

Finally, there's "Teach + Learn," a section specifically dedicated to 9/11 and contextual education. Read through the key questions for a list of a number of the big issues brought up when discussing 9/11, such as how crisis and fellowship work in tandem and how to avoid the idea of the "Other," as fundamentally unlike oneself. There are also two teaching guides, one on artistic response and another on volunteerism. Another feature is a PDF on talking to children about 9/11. One suggestion listed is that 9/11 be addressed through the stories of individuals rather than themes of good or evil. Finally, this section includes webcasts on Middle Eastern culture, memory and memorials, the aftermath of 9/11, and the building of the 9/11 memorial; an interactive timeline; an interactive version of Lady Liberty, a statue bedecked in 9/11 artifacts and ephemera; and information on domestic and international attacks.

Presenting 325 probate inventories, this website provides a unique window into daily life in Virginia and Maryland between 1740 and 1810. In this time period, county courts appointed appraisers, local men, to visit an estate after its owner died, list what was there, and estimate its value. These listings, called probate records or inventories, can be analyzed to illuminate a family's routines, rituals, and social relations, as well as a region's economy and connection to larger markets. These inventories are a sample from the region at this time, picked to be representative of the furnishings in George Mason's Gunston Hall. They are all digitized, transcribed, and searchable.

For a general overview, the inventories can be browsed by decade and county—including York, Norfolk, Richmond, and Fairfax counties in Virginia. For more detailed information on the role of material culture in colonial life, the site's Interpreting section presents interviews with two scholars who use probate records to discuss topics such as slavery and slave life, credit and debt, and women and property ownership. Three detailed lesson plans, written by Virginia teachers, are also available, providing suggestions for incorporating these rich sources into classroom learning.

Wilshire Boulevard runs for 16 miles in Los Angeles, from Ocean Avenue in Santa Monica to Grand Avenue in Downtown. This website offers an interactive journey down the length of this historic street, with more than 100 stops at parks, buildings, and historic landmarks in Westwood/Brentwood, Beverley Hills, Miracle Mile/Carthay Circle, Windsor Square/Hancock Park, Wilshire Center, and the Parks District.

Virtual visitors to Palisades Park in Santa Monica, for example, can see 14 photographs and drawings of the park, spanning from the early 1900s, through the 1940s, and to contemporary photographs, and read a brief description of the park's history. Those interested in the history of architecture will find useful a website feature that allows users to filter all monuments by architect, style, and function. The website also includes a "Memory Book," allowing users to contribute their stories about Wilshire Boulevard and read the stories of others, as they talk about their favorite pizza restaurant in Westwood or their childhood in Beverly Hills in the early 1960s.

This collection features images of dams, hydroelectric power plants, and water supply facilities built in Washington State from the late 1890s to the 1950s. The archive contains 695 items, primarily photographs but also some maps, diagrams, and other documents. A book excerpt on Washington's public water projects from Building Washington: A History of Washington State Public Works (Seattle, WA: Tartu Publications, 1998) by historians Paul Dorpat and Genevieve McCoy provides perspective on the photographs. The collection is notable because "many of these dams, power plants and reservoirs were built in some of Washington's most rugged terrain and had features that represented significant engineering feats of their time." Each image is accompanied by full descriptive and bibliographic data.

The site offers three ways to search the archive of photographs: keyword search, search by collection, or an advanced search option by selected fields and subjects. Or the visitor can browse all the items by selecting "view all items" in the search drop-down menu. This website is a useful resource for those interested in the history of Western hydroelectric dams and other water projects in the first half of the 20th century.

This website functions as an easy-to-maneuver and reader-friendly website for gathering information about Arkansas and its impact on American history. Entries are divided into two categories: text and media. Both include subdivisions based on alphabetical listings or gallery images (respectively) in addition to category, type, time period, race and ethnicity, and gender. The Media section offers numerous photos, maps, documents, and video and audio resources. Entries include suggested readings, related links, and media galleries, when applicable.

Some of the more useful features of the site includes a calendar describing events in Arkansas’s history on each day, as well as a photo of the day from the Arkansas gallery. An overview entry provides general information about the state for those beginning to conduct research about Arkansas, and a breadcrumb trail at the top of each page helps readers retrace their steps while visiting the site—a feature users will find very helpful.

Educators will also find more than 100 lesson plans marked by The Butler Center—when planning for topics such as the Civil War, Korean War, and who’s who in Arkansas history. Lesson plans are in PDF format.

Teachers and students will enjoy exploring how the Razorback State played a key role in U.S. history. Teachers will also find the lesson plans from the Butler Center a useful resource for classroom instruction.

This PBS documentary provides many useful resources for teaching the long and influential history of Jewish Americans. At the heart of this video production is the struggle between identity and assimilation. While Jews in America often faced struggles integrating into new communities, their story is common to other immigrant groups and at the same time a "quintessentially American story."

The site is divided into six main sections. Educators will be particularly interested in the historical background offered in Jewish Life in America (which is divided into eleven subsections), the 30 video segments from the documentary, four lesson plans in For Educators, and links to online resources for teaching Jewish American history.

One noteworthy section of the site is Share Your Story. By allowing Jewish American viewers to submit recipes, immigration stories, or family traditions, this site provides an interactive platform that could enhance any classroom. Students can investigate, research, and conduct interviews with family or friends of Jewish heritage and submit their investigations online. Teachers will also find that the video segments, textual information, and online submission tool can work well together to compliment thematic units on immigration, ethnic identity, and moments in history specific to the Jewish experience.

The Supreme Court is a companion website to a 2008 Parents' Choice gold-award-winning PBS series on the same topic. Under About the Series, episodes can be previewed online, or you can read full transcripts. Another option is to download the discussion guide, intended for use in 9th- through 12th-grade classrooms.

For Educators includes lesson plans, interactives and games, a link to the aforementioned discussion guide, and a list of external resources. Interactives include a timeline, which requires you to put 10 landmark Supreme Court cases in order; a game of memory which requires matching historical figures to facts (ex: Oliver Wendell Holmes to being known as "the Great Dissenter"); and a quiz where you match daily activities such as listening to music or saying the Pledge to relevant case names. The four available lesson plans cover federal v. state power, the 14th Amendment, civil liberties, and the legal importance of precedent.

Note the links to games and a timeline at the top of the home page will take you to a different timeline and set of games. This timeline shows you major Supreme Court and historical events which took place in the year of your choosing. The games include six additional interactives—an explanation of design and architectural decisions as they relate to the Supreme Court; how various types of texts have served as inspiration in Supreme Court decisions; an opportunity to decide which way you think majority rule fell in four cases; matching justices, cases, or issues to quotes; examples of reversal of precedent; and an opportunity to register and predict the outcome of current cases.

Other features available on the website include pages on Supreme Court history (in the top menu of the home page) and additional interviews with Sandra Day O'Connor and John Roberts (in a menu near the bottom of the home page).

In the words of the exhibit website, "The World Trade Center: Rescue, Recovery, Response details the history of the World Trade Center, the September 11 attacks, the rescue efforts, the evidence recovery operation at the Fresh Kills facility, and the public response to the September 11th events."

The website is divided into five sections—The World Trade Center, Rescue, Recovery, Response, and Voices.

The World Trade Center provides a brief overview of the design process, a construction and habitation chronology, statistics on the towers (did you know 17 babies were born at the WTC and that more than 3,500 people worked on the construction site?), a small amount of information on the response to the 1993 bombing, and photographs of several damaged artifacts removed from the WTC towers. The very mundane nature of these objects— for example, floor number signs and a fire extinguisher—may make them more emotionally distressing to students. Proceed with care, but recognize that the inclusion of these artifacts can provide powerful commentary on 9/11.

Rescue shares the story of the first 24 hours following the attacks. The primary focus is on the sacrifice of responders, including 343 NYC Fire Department employees. A timeline breaks the day down into small portions—in some cases minutes—with a an image and sentence describing events. Additional subsections introduce the Engine 6 Company, provide brief remembrances of the members of the company on duty at the time of the tragedy (two of whom survived), interactive schematics and images of the Engine 6 Pumper before and after damage, a description of why the WTC towers' engineering failed, and a selection of artifacts used by rescue workers. This section includes videos in which the two Engine 6 survivors discuss their experiences. These are very emotional, clearly depict pain, and also discuss the men and women that fell from the towers. As a result, educators should take care in their decisions to share these film clips.

Recovery details efforts to recover objects, the deceased, and criminal evidence from the remains of the towers after their transportation to the Fresh Kills site. Here, visitors can find information on and images of the cleanup of Ground Zero; a brief overview of the Fresh Kills site; a to-the-point listing of the sorting process complete with images; images of airplane pieces; photographic panoramas of Fresh Kills; images of items and signs used at the Fresh Kills site; and statistics concerning the site, personnel involved, and objects found. If visitors are concerned, they should be aware there are no images of human remains.

Response addresses the myriad ways in which people responded to the events. The section contains images of newspaper front pages and images of and short introductions to the Union Square scrolls and St. Paul's Chapel memorials, St. Paul's Chapel and Nino's restaurant as places of refuge for recovery workers, and the Fulton Street viewing platform from which the recovery efforts could be watched, as well as photographs of objects and messages of support from around the world.

The final section, Voices, contains lengthy audio interview clips with Patty Clark who worked on the 65th floor of the North Tower; Lee Ielpi who sought his firefighter son; and Jim and Marilyn Geiger, who offer a married couple's perspective on the situation from both within and outside the building. These interviews include individual coping strategies and descriptions of events.

While this is a strong addition to the web content concerning 9/11, it is important to note that it may be a very difficult site for many as it brings human stories of emotional pain to the forefront.

The Yale Digital Commons provides access to sources from the Yale Center for British Art, Yale Peabody Museum of Natural History, Yale University Art Gallery, Yale University Library, and Yale University on iTunes U.

Getting acquainted with the commons can be somewhat daunting. Arrival on the homepage simply offers a keyword search with only a slight indication of the extent or content types of the collections you can search. The description states the contents include "art, natural history, books, and maps, as well as photos, audio, and video documenting people, places, and events that form part of Yale's institutional identity and contribution to scholarship."

The best way to proceed is to select Advanced Search. From here, you can limit a search to items available online. You can also pick one or more of the aforementioned institutions to search within, or choose specific collections which range from African Art or American Decorative Arts to Vertebrate Zoology or Yale University.

Sources you can find using this system include apparel; architectural elements; arms and armor; books, coins, and medals; calligraphy; containers; drawings and watercolors; flatware; fossils; furniture; hardware; inscriptions; lighting devices; jewelry; manuscripts and documents; masks; minerals; miniatures; models; mosaics; musical instruments; packaging; paintings; photographs; plant and animal remains; print templates; scientific instruments; stained glass; textiles; tools and equipment; timepieces; toys and games; sculpture; and wallpaper.
