OFFICIAL49 What does the woman mean when she says this:

[00:00.00]NARRATOR: Listen to a conversation between a student and a librarian.
[00:05.23] MALE STUDENT: Uh, hi, I need to get into Special Collections. In particular the British Literature. [00:11.01]I was working with some of the William Blake books.
[00:13.60]FEMALE LIBRARIAN: Well, then you must know that access is restricted.
[00:16.83]MALE STUDENT: Um, I was in a seminar with Professor Gray, and she authorized access for us.
[00:21.68]FEMALE LIBRARIAN: Oh, if that's the case… let me check. [00:23.75]Right, yeah, but it looks like that expired at the end of last semester.
[00:27.96]MALE STUDENT: But I really need to get back in there. [00:29.99]See, I didn't quite finish my project…
[00:32.98]FEMALE LIBRARIAN: Ah ha, the plot thickens! [00:35.14]Well, it's easy enough; [00:36.80]have Professor Gray authorize you again. [00:39.15]You see, these editions are rare and shouldn't be handled more than necessary. [00:43.11]Can you work from later editions? Or microfilm?
[00:46.54]MALE STUDENT: Not really…[00:47.83]actually my project—well, it involves some annotations in the particular edition here. [00:53.89]They haven't been reproduced because they’re really not part of the text. [00:57.32] generally clean them up. [00:59.02]They’re quite hard to see…
[01:00.71]FEMALE LIBRARIAN: Well, often the characteristics of the manuscripts have been recorded. [01:04.47]These types of extraneous markings might also be noted.
[01:07.40]MALE STUDENT: I don't think they are. [01:08.72] They're very faint, and well, I think I have a new angle on them. [01:12.75] There was a study once a long time ago about these notes that everybody else has since taken for granted, without checking for themselves. [01:19.66]I think there might have been a mistake in the past, that they were misread…
[01:24.03]FEMALE LIBRARIAN: So, get Professor Gray…
[01:26.65]MALE STUDENT: Uh, she's away this semester. I had to beg her to give me extra time on this project. [01:31.95] I haven't even received a grade in the class yet. [01:34.55]And, this class is a prerequisite for other classes in my major. [01:38.83]I really need to see those books so I can finish up this project and get back on course to graduate on time.
[01:45.29]FEMALE LIBRARIAN: Everybody has special circumstances…
[01:48.39]MALE STUDENT: Two hours? One hour? [01:50.42]I promise to be careful. [01:52.18]I just need to look at a few pages with a strong magnifying glass.
[01:56.19]FEMALE LIBRARIAN: Well, I can't let you in without authorization from your professor. [02:00.21]Can you get in touch with her somehow?
[02:02.90]MALE STUDENT: Maybe she's checking her e-mail. [02:05.00]I really thought I'd be able to straighten this out without her. [02:07.90]You know, she did me a huge favor by giving me the extra time. [02:11.42]I feel like I'm skating on thin ice with her…
[02:13.93]FEMALE LIBRARIAN: You know, you were lucky to have had permission to look at the books last semester. [02:17.95]If we don't maintain our policies, they'll disintegrate.
[02:21.16]MALE STUDENT: I know. Would an e-mail from her or a phone call be good enough?
[02:26.08]FEMALE LIBRARIAN: Of course.
