The way to explain the doi and obtain the doi of the literature is as follows:
For students who often need to download the literature, they must be very familiar with the DOI. After all, entering the DOI is the quickest way no matter where they download the literature. But for budding newcomers who have just come into contact with the literature, the first thing that comes to mind when it comes to doi is do i.
1. what is DOI? Why should I download documents through DOI?
the full name of DOI is DigitalObject Unique Identifier, which refers to digital object identifier, and can be understood as the unique "ID number" of digital resources. Doi can be used to identify digital resources such as documents, videos, reports or books.
At present, most academic documents (mainly those after 2) have their own DOI. As long as you know the DOI of a document, you can find out the author, title, journals, official links and other information of the document. Therefore, as long as you enter the DOI of the document in WeChat official account, the server can quickly find the document you need to download and return the download link.
second, the format of DOI:
each DOI consists of a prefix and a suffix, which are separated by "/",and the prefix is divided into two parts by ".". The prefix is determined by the International DOI Foundation, and the suffix is specified by the resource publisher, which is unique for distinguishing a single digital material.
generally speaking, there is no DOI in documents with a long history (before 2). As for Chinese literature, because the use of DOI in China is still in its infancy, it is not possible to download domestic literature through DOI.
all DOI's begin with "1", such as:
1.116/j.food res.217.7.78.
1.18/9563.218.188888886 Baidu Academic (.bing.com/academic) and Google Academic (/) are recommended.
2, search with crossref (https://search.crossref.org/). Open the website and directly enter the title, author or other information of the document to obtain DOI. However, it should be noted that the website is slow to open and needs patience.
3, using Libgen research literature search (http:/http：//gen.lib.rus.ec/scimag//). The disadvantage is that the website may sometimes be unstable and cannot be opened.
