Weeks ago I attended a lecture/seminar in NYU Shanghai, and I am not a student nor an alumnus of it. After the lecture I attempted to ask if I can have a copy of the slides because the content is so interesting. The lecturer said to me that I'd better email her later and she will send me it. And I searched Google for her name and found her email address and shot her an email(using my hotmail email address), but now I still have not recieved the slides.

I thought she doesn't know me and hence might don't know that I am not affiliated to NYU Shanghai. But it seems that she doesn't have any reason to share with me the slides.

When I was a graduate student I attended a lecture on open source and what the lecturer said about it is still whirling in my head: the slides that are not allowed to share are not valuable enough to be shared. I love such ideas, abeit sometimes too idealistic.

But when is it appropriate to ask for a copy of the slides and when it is not?

EDIT after one day of waiting and two additional emails:

Following the suggestion by @WolfgangBangerth I sent the lecturer one more email and she redirected me to the host of the seminar and then I cold-emailed the host with some explanations such as who I am, how I relate to the university and why the slides are important to me. Just now I recieved the slides from the host. Thanks.

It is always appropriate to ask. But some people are unwilling to share their slides for a variety of reasons (none of which I think are particularly good, for basically the reasons you mention in your quote).

So you may or may not get the slides, but it is certainly ok to request them!

In my opinion it is always ok to ask for something. One thing to keep in mind is the question whether the lecture was public. In Austria most lectures from universities are public so anyone can join and listen/participate (only lectures, no seminars).

A reason for you not getting the slides may be that the professor was just busy and forgot to reply to your mail.

Another point to keep in mind is: Do you need all slides? Is there something the interests you particularly and you know the number of the slides. Then I'd suggest to ask for this slide rather than the full set of slides. I've seen situations where lectures have just been copied by a lecturer. So some lecturers might be cautious to send their slides.

The answer depends on what you mean by "OK". If by that you mean "not inappropriate", then sure. It isn't some kind of taboo or insult. But if you mean when is asking even a bit too much, well if they didn't respond apparently it was.

Every email request that requires the other person to perform some new task runs a high risk of crossing that line and not getting a response. I.e. requests where they have to go look something up, or dig out some document to attach, etc. Sometimes people mean to but then forget, but often they just think "nah" and move to the next email.

This is magnified greatly when the person receiving the request is in a position that gets many such requests every day. And moreso in a academic jobs where they are always fighting to get out from their todo list to make time for "real work" like writing and doing research.

Finally, if the person requesting the information has absolutely no relationship with the other person, the odds go down another order of magnitude. In such cases the person is basically a saint if they consistently respond to everyone. Yes I know such people too.

Conversely, I'd note that when you put someone on the spot in person and ask if they will do you some favor such as this, it makes them uncomfortable to refuse directly even if they want to. So they may give you an agreement they didn't mean. Indeed in some cultures it is supposedly impolite to decline a request directly, which is often seen as too blunt. So they will agree (or seem to agree) in a face-saving not-really-agreeing way that is hard for outsiders to read as a refusal.

Saying "e-mail me later and I'll send you the slides" may be a way of telling "no, I won't give you the slides" without starting a discussion as to why not. Same as saying "we will keep you informed" at the end of an interview to a candidate which didn't pass.

It's not impolite to ask, but unless you're entitled to the slides, there's no guarantee that you will get them.

Asking is fine; there's no reason for it not to be.

The top hypothesis that an academic doesn't get back to you about any particular thing must always be, "Too busy; not caught up on the last thousand emails."
