W: Hi, can you help me?
M: Sure, what can I do for you?
W: I’ve got to write an essay on the current teaching methodologies (方法), but I can’t find any suitable books in the education section about this subject.
M: Have you tried the library search engine?
W: You mean where you type the keywords into the computer? Yes, sure. A couple of books come up but they’re not on the shelves. Someone may have taken them out.
M: Well, I can put a reserve on them so that when the person brings them back to the library, we can put them to one side for you, and then I will inform you. Do you want me to do that?
W: Mm, I don’t know. I suppose so, but ideally (理想地；非常合适地), I’d like to get started on my essay right now.
M: Well, there are some other options. Have you used the journal database?
W: No, I have never heard of that.
M: Didn’t you join the library induction tour in the first week of the term?
W: No, I was… I was ill in bed that week.
M: Well, we still offer the tour per week on Wednesdays, and I recommend (建议) you go on one of them. You’ll learn a lot of useful things which will make it extremely easy to use the resources in the library. You can sign up at the desk on the second floor.
W: Yes, I certainly will catch up with that.
M: Well, I’ll just quickly show you how you can use the journal database. First, visit the library homepage on the computer, look, and click on databases in the top right-hand corner. Then you will find all the e-journals available at the university library. And then you can use the search engine and type your keywords to search for journals you want to find. See, if I type in teaching methodologies here, you get over 10000 articles from around the world.
W: Wow, quite amazing.
M: So, that’s a good place to start. If that is not enough, you can always go and talk to your subject librarian. The person for education is George Brown. His office is on the third floor and his phone number is 8674508.
W: Will he be there now?
M: Let me see. What’s the time? 12:10. He’ll probably be at lunch. It’s best to wait and come back at two. He will be working from 2 o’clock to 5 o’clock in the afternoon.
W: OK, thank you for your great help.
