Information technology

When browsing through the subject headings for information technology, I noticed that it seemed to be separated based on country sometimes (if it was available) and then it would place a subtopic which would be how information technology affects it. For example, “Information technology – Environmental aspects” would contain books that talk about information technology in regards to the environment and how it affects our surroundings. Sometimes the subject headings would go further and then specify how information technology affects something like the economy in a certain country, like India. The subject heading helps narrow down your search into something more organized.
