Mainly personal notebooks of engineers, although one is a listing of products of a manufacturer of gears and another is a compilation of shop orders for various products of a manufacturer. They generally contain technical descriptions, drawings, specifications, and financial data.
In the garment industry, workers are paid for the actual number of pieces they complete, regardless of how long it takes. Under federal and state law, however, employers are still required to pay the equivalent of the minimum wage. Manufacturers and some workers point out that piecework rewards those who work quickly and stay focused. However, the system can easily be abused. Despite toiling at breakneck speeds, sweatshop workers often earn substantially less than minimum wage.
On August 2, 1995, police arrested eight operators of the clandestine El Monte garment shop and freed seventy-two Thai nationals who had been working in a form of modern slavery. Workers, recruited in Thailand, were promised good pay and good working conditions. After signing an indenture agreement for $5,000 they were smuggled into the United States with fraudulent documents. The workers were paid about $1.60 an hour with sixteen-hour workdays in horrifying conditions. They were held against their will in a razor wire enclosed complex with an armed guard and were jammed into close living quarters. By 1999, eleven companies Mervyn's, Montgomery Ward, Tomato, Bum International, L.F. Sportswear, Millers Outpost, Balmara, Beniko, F-40 California, Ms. Tops, and Topson Downs, agreed to pay more than $3.7 million dollars to the 150 workers who labored in the El Monte sweatshop. As in most cases of sweatshop production, these companies contend that they did not knowingly contract with operators who were violating the law.

This pocket notebook of Joseph Henry's proceeds from front to middle for about half of the pages, and then proceeds from back to middle, upside-down, for about half of the pages. The notebook contains his notes about sound, ear trumpets, weather (particularly fog), lighthouses, and engines. At the beginning of the upside-down, back-to-middle section is recorded experimental materials (lists of instruments), measurements, and data, all regarding his experiments with sound. Experimental diagrams follow the data and measurements.

This pocket notebook contains Joseph Henry's notes on sound, ear trumpets, engines, and light houses. It also contains diagrams and measurements pertinent to these fields of study. Many of Henry's notes relate to Partridge Island, Canada, and the light house, buoys, and fog signals there. On the last page and back cover, upside-down, are measurements for classifying wind gusts, in relation to velocity.

This notebook is primarily related to Joseph Henry's interests in oil and oil lamps. It begins with a record of Henry's travels in New England in September 1865, and then proceeds to document Henry's notes, conversations with other scientists, research, and experiments in relation to lard oil. He dates his entries and includes drawings and diagrams of his experiments. There are also notes about an engine that Henry worked on, and notes about weather phenomena such as water spouts, tornados, and thunderstorms.

Edited film is the story of the Kreznar family vacation to Florida created by Frank Kreznar, an award winning amateur filmmaker and engineer. The youngest daughter is instructed by a teacher to keep a notebook of her experiences in Florida which include visiting a Florida visitor center, setting up camp in a park, watching a water skiing performance, visiting a marine animal park where they watch a dolphin show, touring the Everglades on an air powered boat, riding on a glass bottom boat, viewing bird and animal wildlife and swimming at a beach. Sound is the daughter's narration of their experiences.

This pocket diary was originally a "Churchman's Diary and Ecclesiastical Calendar" for the year of 1854, but Joseph Henry used it as a pocket diary for the year of 1865. On some pages he has not made notes, so some original content in the diary (calendars, tables of bishops and dioceses, etc.) remains unmarked. However, he has used many memoranda and weekly calendar pages to make his own notes. About half the diary is written proceeding from front to middle, and half of it is written upside-down, proceeding from back to middle. Henry's notes regard such topics as oil lamps, fog signals, engines, reports and papers to exchange among colleagues, and weather in different parts of North America.
From hidden figures to musings on how birds fly, Leonardo da Vinci’s notebooks have long been known as treasure troves of art and science. And it turns out that, 500 years after the master doodled in them, the notebooks still have some secrets. Now, a study of da Vinci’s notes and sketches has revealed something unexpected indeed: the first written evidence of the laws of friction.
In a new study in the journal Wear, an engineer from the University of Cambridge describes how he found the artist’s first writing on the laws of friction in a tiny notebook that dates from 1493 housed in the Victoria & Albert Museum in London. The text and accompanying sketches are apparently evidence of da Vinci’s earliest experiments in friction.
In a statement, researcher Ian Hutchings says that the writing demonstrates that as early as 1493, da Vinci understood the laws of friction. The artist and polymath is now known as the father of tribology, which explores the science of surfaces in motion and how they interact with one another. Friction, lubrication and wear are all part of tribology, and all three topics were explored in depth by da Vinci. He used pieces of dry wood to understand how resistance and friction worked—experiments that have been recreated by other scientists nearly 500 years later.This doodle represents the first time anyone wrote about the laws of friction. (V&A Museum, London )
Hutchings created an extensive timeline of da Vinci’s statements on friction and describes the newly-discovered notes and sketches, which portray blocks being pulled over surfaces with a string. “Friction is of double the effort for double the weight,” wrote the master. This is a different version of Amontons' first law of friction, which states: friction is proportional to the force with which an object is loaded. Guillaume Amontons, after whom the law is named, conducted friction experiments in the 17th century, but the law has long been nicknamed “da Vinci’s law of friction” due to other experiments discovered in his notebooks. Now, it appears that he did indeed state the law 200 years before Amontons, who apparently was unaware of da Vinci’s work in the field.
Ironically, the doodle and text had previously been dismissed by art historians, who preferred to focus instead on a sketch of an old woman adjacent to the scribbles. The artists scribbled the quote “cosa bella mortal passa e non dura” (a line from Petrarch that means “mortal beauty passes and does not endure”) beneath the sketch of the woman. But as long as da Vinci’s notebooks keep revealing the depth of the master’s brilliance, interest in their contents—both artistic and scientific—will never die.
Rich Madrid’s notebook is a handmade encyclopedia of machine-stamped parts produced at the NUMMI plant. Each page contains a small picture of the part as well as its part number, part name, model name, and other pertinent details relating to its production. This book is a prime example of Toyota’s concept of kaizen, or worker-led improvements. The book made it easy for Rick to make sure parts were machined to specifications.

The papers document the life and work of William R. Hutton, a civil engineer during the late 1800s to the early 1900s. Materials include diaries, notebooks, correspondence, letterpress copy book, printed materials, publications, specifications, photographs, drawings, and maps that document the construction of several architectural and engineering projects during this period. Most notable are the records containing information related to the construction of the Chesapeake and Ohio Canal, Hudson River Tunnel, the Washington Aqueduct, the Kanawha River Canal, and the Washington/Harlem River Bridge. There are also several records about railroads in the state of Maryland, the District of Columbia and elsewhere, including the Western Maryland Railroad, Baltimore and Ohio Railroad, Colorado Midlands Railway, Baltimore and Drum Point Railroad, the Northern Adirondack Railroad, and the Pittsfield and Williamstown Railroad. The records can be used to track the progression of these projects, and engineering innovation during the late 1800s to the early 1900s.
