Literature retrieval skills are the first step on the path of scientific research, and having a firm grasp of this skill can help us to get the latest advances in the discipline and update our professional knowledge. But for novice Xiaobai, looking for literature is like finding a needle in a haystack, and finding literature is not as simple as Baidu searching.
So many databases, their types of inclusion and literature direction, what are the advantages and disadvantages, according to their own needs should search which database, everywhere is learning.
Here is a scientific researcher to help you classify and sort out the commonly used database resources in biomedicine and share them with you.

Full-text databases
CNKI, Wanfang, Weipu, etc., these are comprehensive databases, which can be downloaded in full. It includes all subject categories, but the corresponding scope of inclusion will be different.
The Chinese biomedical literature knowledge base CBM is only for biomedicine, so there is no need to use CBM to search for non-biomedical content.
Summary database
Compared with the full-text database, the abstract database provides us with only the abstract of the paper instead of the full text, and the more common and easy to use is the well-known PubMed and EMbase.
PubMed will have a "Full text" prompt, but only give a full text link, not necessarily to get the full text. If you want to get the full text through such a database, you need to use some plug-ins to achieve, the space is limited, and the scientific researcher will not give you details here.
Database retrieval platform
Very famous is our OVOD platform! OVID includes many databases, such as MEDLINE database, EMBASE database, through OVID to search, you can retrieve documents containing these two databases or other databases, there is no need to search individually.
The biggest advantage of such a database for us is that it can be more fully searched, and depending on the scope of the database inclusion, it may retrieve documents that we cannot retrieve through the above two types of databases. In addition to OVID, the same type of database is EBSCO and so on.
Literature search engine
Common ones are Google Scholar, Baidu Academic, Bing Academic, etc., which are to integrate all published papers together for our search. However, compared with traditional databases, the search methods of these search engines are relatively single, and they are not as comprehensive as our database search methods, so it may be difficult to accurately find the search results during the search process.
search engine
When you see this, you may think that search engines and literature search engines are not the same thing? But in fact, there is a certain difference, simply put, the difference between "Google Scholar" and "Google Search".
Sometimes our literature is not included in the literature search engine, but when searching through the search engine, the full text can be searched. Therefore, it can be said that the search engine is a supplement to the literature resources of the literature search engine, and the common search engine is the well-known Google, Baidu and so on.
In general, when we search for literature, we usually search only for these five types. If you master their skills, you will be able to find exactly the "needle" you want in this sea of literature.
