Foreign authors are friendly and basically willing to give. But there is no contact information of the author on PUBMED. You can find his email address and personal homepage in the following ways. First, some PUBMED abstracts directly provide the author's email address. After finding the abstract with PUBMED, click on the author's name to find other articles published by him and display them in abstract format. Maybe you can find his email directly. Note: First, there may be abbreviations and duplicate names, and the author's unit can judge whether it is the same author. Secondly, only the email of the first author will be displayed, so you should use LIMITS to limit your search to the first author. The method is to leave only the first letter in the search box, and then click Limit. Select the first author in DEFAULTTAG. Second, if the method fails, you can find its unit in the PUBMED abstract, which is generally ok. Then, copy its unit name, use Google search, you can find the unit's website, enter and select the staff to find it. You can use IE to edit, search (on the current page) and enter the author's initials to speed up the search. Three. After finding the abstract with PUBMED, you can find other articles published by the author by clicking his name. Maybe you can find the full text for free or through the database ordered by the school, and you can find the author's contact information in the full text. The precautions are the same. Fourth, using the second method, you may find the author's personal homepage in the author's introduction. Free full text may be provided on the personal homepage. Use method 2 to find the website of the laboratory. The full text can be found inside.
