Problem: Background: The New York Public Library (NYPL) is a public library system in New York City. With nearly 53 million items and 92 locations, the New York Public Library is the second largest public library in the United States (behind the Library of Congress), and fourth largest in the world. It is a private, non-governmental, independently managed, nonprofit corporation operating with both private and public financing. The library has branches in the boroughs of Manhattan, The Bronx, and Staten Island, and affiliations with academic and professional libraries in the metropolitan area of New York State.
Context: The Library website provides access to the library's catalogs, online collections and subscription databases. It also has information about the library's free events, exhibitions, computer classes and English as a Second Language (ESL) classes. The two online catalogs, LEO (which searches the circulating collections) and CATNYP (which searches the research collections) allow users to search the library's holdings of books, journals and other materials. The LEO system allows cardholders to request books from any branch and have them delivered to any branch.  The NYPL gives cardholders free access from home to thousands of current and historical magazines, newspapers, journals and reference books in subscription databases, including EBSCOhost, which contains full text of major magazines; full text of the New York Times (1995-present), Gale's Ready Reference Shelf which includes the Encyclopedia of Associations and periodical indexes, Books in Print; and Ulrich's Periodicals Directory. The New York Public Library also links to outside resources, such as the Bureau of Labor Statistics' Occupational Outlook Handbook, and the CIA's World Factbook. Databases are available for children, teenagers, and adults of all ages.  The NYPL Digital Collections (formerly named Digital Gallery) is a database of over 700,000 images digitized from the library's collections. The Digital Collections was named one of Time Magazine's 50 Coolest Websites of 2005 and Best Research Site of 2006 by an international panel of museum professionals.  The Photographers' Identities Catalog (PIC) is an experimental online service of the Photography Collection in the Stephen A. Schwarzman Building.  Other databases available only from within the library include Nature, IEEE and Wiley science journals, Wall Street Journal archives, and Factiva. Overall, the digital holdings for the Library consist of more than a petabyte of data as of 2015.
Question: what was uploaded onto the site?
Answer: reference books in subscription databases, including EBSCOhost, which contains full text of major magazines; full text of the New York Times

Background: James Watt  (30 January 1736 (19 January 1736 OS) - 25 August 1819) was a Scottish inventor, mechanical engineer, and chemist who improved on Thomas Newcomen's 1712 Newcomen steam engine with his Watt steam engine in 1781, which was fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world. While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines. He realised that contemporary engine designs wasted a great deal of energy by repeatedly cooling and reheating the cylinder. Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines.
Context: From an early age Watt was very interested in chemistry. In late 1786, while in Paris, he witnessed an experiment by Berthollet in which he reacted hydrochloric acid with manganese dioxide to produce chlorine. He had already found that an aqueous solution of chlorine could bleach textiles, and had published his findings, which aroused great interest among many potential rivals. When Watt returned to Britain, he began experiments along these lines with hopes of finding a commercially viable process. He discovered that a mixture of salt, manganese dioxide and sulphuric acid could produce chlorine, which Watt believed might be a cheaper method. He passed the chlorine into a weak solution of alkali, and obtained a turbid solution that appeared to have good bleaching properties. He soon communicated these results to James McGrigor, his father-in-law, who was a bleacher in Glasgow. Otherwise he tried to keep his method a secret.  With McGrigor and his wife Annie, he started to scale up the process, and in March 1788, McGrigor was able to bleach 1500 yards of cloth to his satisfaction. About this time Berthollet discovered the salt and sulphuric acid process, and published it so it became public knowledge. Many others began to experiment with improving the process, which still had many shortcomings, not the least of which was the problem of transporting the liquid product. Watt's rivals soon overtook him in developing the process, and he dropped out of the race. It was not until 1799, when Charles Tennant patented a process for producing solid bleaching powder (calcium hypochlorite) that it became a commercial success.  By 1794 Watt had been chosen by Thomas Beddoes to manufacture apparatus to produce, clean and store gases for use in the new Pneumatic Institution at Hotwells in Bristol. Watt continued to experiment with various gases for several years, but by 1797 the medical uses for the "factitious airs" had come to a dead end.
Question: why did it come to a dead end?
