Read the following passage carefully. Then answer the questions or complete the statements in the fewest possible words.
The library is one of the most popular places at a Western university. Students turn to it for research, conversations about class, and many other services.
Compared with Chinese libraries, college libraries in the US and UK tend to offer more resources. A graduate student at Yale University can borrow as many as 225 books at a time.
In addition to borrowing books, there are online and electronic resources. These include a database (数据库) search of popular and academic material, such as LexisNexis Academic, which offers items from newspapers and magazines.
Although books and articles are the items that students ask for most frequently, some libraries provide video recordings. At some schools, teachers and tutors put electronic copies of their teaching PPTs on the library Web to give easier access for students.
Another useful service in Western college libraries is the Interlibrary Loan. This allows a student at one school to borrow books from another school. The loan request is made through the student’s college library, which gets the book, gives it to the user, and arranges for its return.
Technology has made libraries more attractive. Some universities have services for students to send messages through the computer.
Earlier this year, Harvard University introduced a new Scan and Deliver service, allowing students to make requests for parts of books and articles. Requests made through the system are handled by library staff. The student receives an e-mail with an Internet link to the scanned pages. The service is free and all material comes within four days.
It used to be that libraries didn’t allow food or drinks. But that rule is changing and many of them now contain a café so students can spend as much time as they want in the library.
Additionally, some US university libraries are now all-night affairs, or have at least one study room open all night.
