I am conducting a systematic literature review searching articles from four electronic databases. But the articles I retrieved seem to contain inadequate information to achieve the objectives of the review. I am thinking to extract information from webpages which I know contains information I want. My concern is in searching the webpages I won’t use search terms as I have done for databases. Would you advise me to continuing the search the webpages? Will the method still remain scientifically sound?
Method: Abstracts will be searched from electronic databases. In addition, webpages of government authorities will be searched to extract the information.
