At the stage of topic selection, there is no paper direction yet, and I want to find a suitable direction to do it. At this time, I can search for "review" and "investigation" on the Internet, look at some literature reviews and find my interested direction;

We have determined the general direction and want to know the progress in this research field. At this time, it is necessary to consult experts in this field, find out who are outstanding people in this field, and search their articles-foreign traditions, many magazines will invite cattle people to write a summary when introducing achievements and progress in a certain field-only by knowing who are outstanding representatives in this field can we appreciate the wonderful development in this field from their works.

Skillfully use three tools:

(1) To consult international literature, you should be proficient in using the Science Network (/). This database is recognized as one of the necessary databases for scientific research in the world.

(2) China literature, it is suggested to use "China HowNet" skillfully. At present, this network database has gradually approached the Science Network, adding many functions. Wanfang, VIP.

(3) For Chinese and English materials, it is recommended to use "Google Academic". Google Academic Search provides a simple way to search academic literature extensively. You can search many disciplines and data sources from one place: peer-reviewed articles, papers, books, abstracts and articles from academic publishers, professional associations, preprints, universities and other academic organizations. Help you identify the most relevant research in the whole academic field. The functions of academic search include: conveniently searching all kinds of resources from one place, finding reports, abstracts and quotations, finding complete papers through your library or on the Internet, and learning about important papers in any scientific research field.

If you know the name of an article, you might as well enter the name to have a look-there is one more word here, because the full text of foreign papers is generally in pdf format, so you might as well add a "[pdf]" before the name of the entered paper, for example, "[PDF]+a survey of corporate governance" can be used as a keyword search, but the full text searched by Google is often just a working paper, and there is no magazine number and page number, so in

If you can't find the papers you need through these full-text databases, you might as well write down the page numbers of the journals that publish the papers (for reference), and then search their working papers on Google. If you can't get it on Google, you can try searching the author's home page, maybe there will be one on it. If not, you can try to write directly through the author's mailbox. Foreigners are more enthusiastic. If all these methods have been tried, you can finally consult domestic collections in EBSCO for help. Generally speaking, most classic papers will be put on the internet by busybodies, so you can't get a document by trying all the above methods, either giving up reluctantly, asking for help from foreign friends or indirectly quoting other documents.

There is another aspect worth mentioning in collecting literature. Foreign papers have been published for a long time, and the papers we see now may actually be works written two or three years ago. Therefore, to grasp the research trends, it is best to read the working papers, so as to understand what others are studying now. With the writing of the paper, this working paper may have been published. At this time, you might as well check its published periodicals online and list the published materials as your reference, so that the annotation of your paper will be more standardized and take into account the requirements of annotating the latest literature.

Finally, there are several good websites that offer free downloads of working papers: IDEAS(http://ideas.repec.org/) and NBER(www.nber.org). In addition, many universities and research institutions also provide free download addresses for their working papers, such as IDEI (http://idei.fr/presentation.) founded by Professor Lafonte.
