Amir: Hi, er, can you help me?
Librarian: Sure, what's the problem?
Amir: I've got to write an essay on electrical distribution and transmission systems, but I can't find any suitable books in the engineering section on level three.
Librarian: Have you used the library search engine?
Amir: You mean where you type the keywords into the computer?  Yes, I've done that.  A couple of books come up but they're not on the shelves, someone's taken them out.
Librarian: Well, I can put a reserve on them so that when the person brings them back to the library, we can put them on one side for you.  Do you want to do that?
Amir: Mmm, I don't know.  I suppose so, but ideally, I'd like to get started on my essay sooner rather than later.
Librarian: Well, there are some other options.  Have you used the journal database?
Amir: No, what's that?
Librarian: Didn't you go on a library induction tour in the first week of term?  They were running five days a week, morning and afternoon.
Amir: No, I was, er, I was ill that week.
Librarian: Well, we still do two library inductions a week on Wednesdays, and I recommend you go on one of them.  You'll learn a lot of useful things.  You can sign up at the desk on level two.  
Amir: Yes, I probably should do that then.
Librarian: Well, I'll just quickly show you how you can use the journal database.  If you go onto the library homepage on the computer, look, and click on databases, here in the top right hand corner, it takes you to all the e-journals that we have access to here at the university library.  You can use the search engine to find journals that are related to your keywords.  See, if I type in electrical transmission, you get over five thousand articles.
Amir: Wow.
Librarian: So, that's a good place to start.  Meanwhile, you can always go and talk to your subject librarian.  The person for Electrical Engineering is Mark Taylor.  His office is on level four.
Amir: Will he be there now?
Librarian: Let me see.  What's the time?  Twelve fifteen.  He'll probably be on lunch, or if not, he'll be going at twelve thirty.  You'd be best to wait and come back at two-ish.  Then you'll be more likely to catch him.
Amir: Okay, thank you.
