Dear student,

I hope you are doing well, if are searching for articles based on research you will have to check on authorized data basis like

ScienceOpen.

Directory of Open Access Journals.

Education Resources Information Center.

arXiv e-Print Archive.

Social Science Research Network.

Public Library of Science.

OpenDOAR.

These are usually free of cost so u can access them in a very convenient way. They will help u alot or try Nlist database im a science bsc student i usually use nlist resources comes quite handy...

Now to know if an article is authentic u will have to check the references. References play a vital role to help know if a document is authentic or not.

Hope this helps!!
