D Using the Internet and CD-ROM databases in the library Bramley College now has full electronic information resources in the College Library to help you in your studies. On CD-ROM in the library we have about fifty databases (数据库) , including many statistical sources. Want to know the average rainfall in Tokyo? It’s easy to find out. You can conduct your own CD-ROM search for no charge, and you can print out your results on the library printers using your library photocopying card. Alternatively, you can download your results to disk, again for no charge, but bring your own USB flash disk ( U盘 ) or CD-ROM. If you are not sure how to conduct a search for yourself, librarians can do it for you , but we charge $5 each time for this service, no matter how long or how short a time it takes. All library workstations have access to the Internet, so you can find the Web-based information you need quickly and easily. If you are unfamiliar with using the Internet, help is available in several ways. You can start with the online tutorial ( 指南) Netstart. The tutorial will take you through the basic step to using the Internet, at any time convenient to you. If you prefer, ask one of the librarians for Internet advice ( at times between 8:00 am and 12：00 am weekdays ) or attend one of the introductory group sessions that are held in the first two weeks of each term. A word of warning: demand for access to library workstations is very high, so you are strongly advised to book a workstation, and we have to limit your use to a maximum of one hour at any one time. Also, use of the computers is limited to students only, so you may be asked to show your Student Identification Card to make a booking, or while using the workstations. 68.
