The Library of Congress

Since the early 1970s, the construction of railways in the USA has dramatically increased. Before 1871, about 45,000 miles of railroad was laid. Between 1871 and 1900, the country's growing railway system increased 170,000 miles. Most of the growth is due to the construction of a transcontinental railroad. In 1862, Congress passed the Pacific Railroad Act, which approved the construction of a transcontinental railroad. Such a first railroad was completed on May 10, 1869. By 1900, the other four transcontinental railroads connected eastern provinces and the Pacific coast.

Four of the five transcontinental railroads were constructed with the aid of the land with the help of the federal government. Millions of acres of public land were received from Congress. It was secured for railway and sale, and its benefits helped the company to fund its railway construction. However, not all railroads were built with the help of the government. Small railroads have to purchase land from private owners, some of them oppose the railroad and refuse to grant access

It is very difficult to lay tracks and live in railway construction camps. Railway contractors are not only influenced by extreme weather conditions, they also have to go through many natural terrain such as rivers, canyons, mountains, deserts. Like other major economic opportunities in developing countries, railway construction camps are attracting all kinds of people and are seeking ways to make almost all people legitimately or illegally profitably profitable. Life in the refugee camp is very rude and impolite

By 1900, most of the country 's railway system was upgraded. The railroad opened up a way to settle in the West, provided new economic opportunities, stimulated the development of the towns and communities, and generally connected the provinces. When the railroad was closed during the Great Railway strike in 1894, the true importance of the railway was fully reflected.

To search for other US documents related to this topic we will use the term railway, including land grants, construction and construction camps in 1894, transcontinental and other railroad strikes.

The term "illegal alien" is the subject of the Congress library. "The subject heading of the Library of Congress (LCSH) has actively maintained the information directory of the Library of Congress since 1898" (http://id.loc.gov/) in the article " The way people use will be our parents The choice is a crime to provide us with a better life and to completely compromise the courageous choices and obstacles we have overcome to survive (Http://www.nytimes.com). Undocumented immigrants claim to be survivors devoted to a better future Padilla said the term "illegal aliens" Regardless of its legal status, I think that it is being used to respect Mexican immigrants, "foreigners" and "illegal aliens" are disapproved by resolution of the American Library Association. Padilla and Dartmouth students spent more than two years trying to delete topic titles.

Does the Congressional Library title continue for another 100 years? LCSH - Introduction to the Library of Congress Libraries (LCSH) is organized by the American Library Congress to maintain the subject headings of bibliographic records (Hiorland, 2007). As necessary, topic headings are formed to classify and catalog the books included in the library. If the book is classified as a distinguishable topic for reference and accessibility by users and librarians, a new title will be given.

There is only one name authorization file in the US library. Congressional libraries are responsible for maintaining them. The authority of many subjects including the subject heading of Congress library's heading (for most academic libraries), the headings of Sears topic (for most public libraries), the medical subject headline (maintained by the National Medical Library and used in medicine) There is a document. Library etc) The catalog record you find back to where you can not see it will identify the topic permission file it uses. Like the name permission file, the subject permission record contains cross-references, so you can find the topic title you need, even if it is not completely correct. But whichever you write an authoritative record, you will expect what you are looking for.
