The University of Missouri Digital Library has a range of digital collections covering much of the fine Show Me State, along with other regions of the United States and the globe. This particular collection brings together key documents that tell the story of British religious, legal, and political history from the 1600s to the 1800s. Visitors can browse at their leisure or perform complex searches across the entire collection. It is impressive indeed, as it contains over 20,000 items that were purchased by the university beginning in 1943. Many of these documents were published anonymously, due to their possibly inflammatory and controversial subject matter. It's fun to just look around, as visitors can find items like the 1642 pamphlet "What kinds of Parliament will please the King" and 1643's "A Second Complaint: being an honest letter to a doubtfull friend, about the rifling of the twentieth part of his estate."

The University of Houston has increased its digital offerings in recent years to allow visitors to make their way through everything from home retail pamphlets from the 1920s to copper plate engravings from Theodor de Bry's "Grandes Voyages." This particular collection offers users access to 80 different menus from the 1850s and 1860s. The menus are taken from establishments that were located all over the country, such as the American Hotel in Buffalo and the Allyn House in Hartford. It's quite a revelation to learn that on March 5, 1859, the patrons at the Allyn House would have had access to over 35 menu options, including oyster fritters and halibut. Culinary historians and gastronomy types will have a field day with these menus, which might inspire a rather elaborate repast.

The transit of Venus is a rare astronomical event that has been well documented throughout history. The most recent transit occurred in June of 2004, and the one before that took place more than 100 years earlier in 1882. This site from the South African Astronomical Observatory provides information and first-hand observations of the 1882 event from Wellington, South Africa. Just prior to the event, an observatory was erected at the Huguenot Seminary for girls, and some of the historical observations made from that site in 1882 are provided here for your perusal.

During the 19th century, the ever-popular trade card was a way for American businesses to effectively promote their goods and services. Some examples include a colorful business card depicting freshly caught mackerel in a net (appropriately enough for "Deep Sea Mackerel") and the Charter Oak Lawn Mower, which feature two Victorian women enjoying a leisurely mowing session in a pastoral setting. This online collection was created by Harvard Business School's Baker Library, which happens to have over 8000 of these cards. The online archive contains around 1000 cards which date from the 1870s to the 1890s. Visitors can search this archive via Harvard's Visual Information Access (VIA) union catalog which will allow them to focus in on subjects of particular interest. Finally, visitors can also avail themselves of the site's digital exhibition entitled "A New and Wonderful Invention: The Nineteenth-Century American Trade Card".

Over a century ago, Yiddish theater was all the rage in New York and other major American cities with a sizable Jewish population. A wide range of well known performers (such as Paul Muni and Leonard Nimoy) cut their teeth on these stages. Of course, the 2nd Avenue corridor in New York City held many of these Yiddish theaters and this site from the New York University Libraries seeks "to capture the memory and to convey the feel of 2nd Avenue as a living part of the history and culture of New York and America." Visitors to the site can browse around the Multimedia area to listen to oral histories or check out some video clips. The Photos area includes a history of Yiddish theater in New York along with several family photo albums. The site is rounded out by a collection of related radio programs and stations.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

The activity explores the three states of matter and Newtonäóťs Laws of Motion.

In this activity, learners build small indoor paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw. This lesson plan includes procedures for the two part activity, background information, diagrams for making Ares 1 paper rockets, discussion questions, extensions, and black-line masters for learners.

In 1968, Dr. Martin Luther King Jr. traveled to Memphis to support striking sanitation workers. On the evening of April 3, King delivered his "I've Been to the Mountaintop" speech to strikers and their supporters. The very next day, he was assassinated. This site takes visitors through the experiences of those who were there and also through the words of Dr. King during his time in Memphis. Visitors can find video clips, a chronology of the 1968 strike, and a transcript of King's famous speech.

Born in 1828 in Nunda, New York, Andrew J. Russell worked as a portrait and landscape painter as a young man. In 1862, he organized a local militia unit for service in the Civil War and he learned the craft of photography along the way. Several years later in 1868, he began a project to document the construction of the Union Pacific railroad during its long march to its meeting point with the Central Pacific in Promontory Point, Utah. Russell made three trips west in 1868 and 1869, and he made several hundred plate negatives as part of his extensive work. The Yale Collection of Western Americana has a great deal of his work, and this digital collection brings together a diverse set of these materials for consideration by the public. On the site, visitors can browse through these images, which include bridge construction photographs, shots of the surrounding landscapes, and men at work.

A video from the Extreme Ice Survey in which Dr. Tad Pfeffer and photographer Jim Balog discuss the dynamics of the Columbia glacier's retreat in recent years through this time-lapse movie. Key point: glacier size is being reduced not just by glacial melting but due to a shift in glacial dynamics brought on by climate change.

While some may harbor antiquated and erroneous impressions of librarians, those in the know can attest that these invaluable professionals like to get out and about just like their kinfolk in other learned professions. There is ample historical proof of this fact offered by this website, which contains a selection of digitized documents from the American Library Association (ALA) Archives, housed at the University of Illinois at Urbana-Champaign. Currently, the digitized collections include the F.W. Saxon Photographs Collection and the Library Building Photographs Collection. The Saxon Collection includes over 170 group pictures of librarians attending the ALA conferences in the US and Canada from the period 1894 to 1932. The Library Building Collection is quite intriguing, as it contains 78 postcards of libraries from locales such as Gadsden, Alabama.

This activity lets you program your 'robot' (a willing friend) to pick up and dispose of some 'toxic waste' using as few commands as possible. Learners create command cards (Turn Left, Right, Forward 1, etc.), mark out a simulation area on the floor, and try to get the "robot" to dispose of something that serves as "toxic waste" into something that serves as a "containment vessel" - in as few steps as possible. Strategy, predication and cooperation are all part of this activity.

The experiments are designed for small groups in a classroom or after school setting. Each of the experiments gives students a clue to solve the mystery.

Setting out on the Caribbean today on a large vessel might involve boarding a massive cruise ship in Fort Lauderdale or Nassau in the Bahamas. Things were a bit different when Aaron Thomas set off on those same waters back in 1798. Thomas served on the HMS Lapwing during the French Revolutionary wars and his journal contains first-hand accounts of naval operations, customs of the day, and humorous anecdotes involving shipmates and superiors. This wonderful volume is physically located at the University of Miami Libraries Special Collections Division, but visitors can read the document on this site. One sample contains this chestnut of an observation: "Never stop at an Inn, nor go into a Shop to buy goods, if you see the Master has a Superfine Coat on." The document includes pen sketches, financial records, and graveyard epitaphs collected during Thomas's forays ashore. Visitors can click on the Biography area to learn more about Thomas and also use the Excerpts area to get a flavor for his prose style.

The abacus has been around for several thousand years, and it is an efficient and interesting counting machine. The standard abacus can be used to perform addition, subtraction, division, and multiplication, along with its use in extracting square roots and cubic roots. This site was created by Luis Fernandes, and it explores the wide world of the abacus through illustrations, thoughtful essays, and other items. On the site's homepage visitors can read a detailed introduction to the abacus, look over an interactive abacus tutorial, and learn about the history of the device.

In the process, students develop an understanding that science theories change in the face of new evidence. This acitivity is part of the "Swift: Eyes Through Time" collection that is available on the Teacher's Domain website.

This case was developed for use in the first semester of a sophomore organic chemistry laboratory to illustrate how a combination of techniques is usually required in the identification of chemical compounds. It involves a murder mystery with a forensic twist. Students are told that two bodies have recently been recovered from two different lakes. Due to a mix-up at the morgue, the coroner's office is unable to determine which body came from which lake. The students' task is to develop a methodology to solve this mystery as well as determine whether the deaths were the result of murder or mishap. The case could also be used in instrumental analysis courses or adapted for a non-majors course in the general education curriculum.

The goal of the Afghanistan Digital Library at New York University is "to retrieve and restore the first sixty years of Afghanistan's published cultural heritage." This period, from 1871 to 1930, is of great importance as the earliest publications from this time frame are very rare and decades of war have not helped the situation. A team of scholars working at the National Archives in Kabul and NYU has helped to digitize a number of these documents for inclusion in this digital library. The project is sponsored by NYU Libraries, the National Endowment for the Humanities, and The Reed Foundation. Currently, the archive contains over 380 books, and visitors can browse them at their leisure. There is a search feature, but as the transliteration part of the project is still in development, visitors might just want to look around at items they find compelling. The viewer application is quite user-friendly, and visitors can zoom in to examine various details of each work.

Based at the East Central Georgia Regional Library, the African American Funeral Programs collection consists of over 1,000 funeral programs dated from 1933 to 2008. Most of the programs are from churches in Augusta, Georgia, and the surrounding area, with a few outliers coming from New York and Florida. These materials are tremendously important historical resources, as most programs contain a photograph of the deceased, an obituary, and a list of surviving relatives. Visitors can browse the collection by name, year of death, city, or funeral site. Additionally, they may wish to use the advanced search feature on the homepage. First-time visitors may wish to click on the featured obituary on the "From the collection" graphic. It's a remarkable collection and one that is worth passing along to friends and colleagues.
