1
00:00:00,500 --> 00:00:00,830
Okay.

2
00:00:00,840 --> 00:00:06,330
Next, how do you get the research paper? And most importantly how do you get it for free?

3
00:00:06,330 --> 00:00:11,640
And the first thing you can do is to use your university library. Your university will most likely have

4
00:00:11,640 --> 00:00:17,130
an electronic library of research papers and most of the time you will find the research paper that

5
00:00:17,130 --> 00:00:19,920
you are looking at in that library for free.

6
00:00:19,920 --> 00:00:25,890
Another thing you can do is to google the paper or check out the website of the first author. And you

7
00:00:25,890 --> 00:00:26,780
might be surprised.

8
00:00:26,820 --> 00:00:34,050
This very often works because very often the first author gives away the paper for free on his Web site.

9
00:00:34,050 --> 00:00:38,340
Another thing you can do is to email the first author and ask for the paper.

10
00:00:38,540 --> 00:00:43,170
And this may sound a little bit weird. To ask for a paper that you normally need to pay for to get it

11
00:00:43,170 --> 00:00:43,990
for free.

12
00:00:44,190 --> 00:00:48,930
But with a 95 percent chance the author will be happy to give you the paper.

13
00:00:49,170 --> 00:00:54,270
And the reason is that the people who actually want you to pay for the paper are not the authors but

14
00:00:54,270 --> 00:00:55,270
the Journal.

15
00:00:55,320 --> 00:01:00,870
Most of the time the author will be happy if as many people as possibly actually read his or her paper.

16
00:01:00,870 --> 00:01:04,620
So very likely the author is just going to give you that paper.

17
00:01:04,620 --> 00:01:08,120
So that's how you can get pretty much every research paper for free.

18
00:01:08,190 --> 00:01:11,040
Okay next let's talk about how you scan a research paper.
