Table 1: This table provides a list of free, online academic search engines for various science disciplines.
Note: The results of academic search engines come in the form of an abstract, which you can read to determine if the paper is relevant to your science project, as well as a full citation (author, journal title, volume, page numbers, year, etc.) so that you can find a physical copy of the paper.
It turns out that just plugging search terms into a regular search engine, like Google, Yahoo, or MSN, isn't very effective.
The pages you get back will be a wide mixture of websites, and very few will be links to peer-reviewed scientific papers.The remainder, like the ISI Web of Science, are subscription-based.Universities and colleges often subscribe to academic search engines.As mentioned above, some search engines provide links to free online versions of the paper, if one exists.If the search engine doesn't, or if you got the citation somewhere else, like the bibliography of another science paper you were reading, there are several ways to find copies.Visit Business Insider's homepage for more stories.Established in 2004, Google Scholar is a massive database of scholarly literature that allows users to access information, cross reference it with other sources, and keep up with new research as it comes out.Using Google Scholar, you can access these kinds of sources: Journals Conference papers Academic books Pre-prints Theses and dissertations Abstracts Technical reports Other scholarly literature from "all broad areas of research" Here's more about the powerful research tool.Who can use Google Scholar Anyone can access the search database.Related coverage from How To Do Everything: Tech: How to write a Google review, and become a 'Local Guide' for your area How to change your Google username's display in Gmail How to drop a pin on Google Maps from your desktop or mobile app How to make a brochure on Google Docs for your company or cause Google Scholar is a searchable database of scholarly literature.Reading scientific literature is a critical part of conceiving of and executing a successful advanced science project.
