2. Google Scholar

2.2. Additional options

Google Scholar enables the creation of citations for items – click on the quotation marks below the record and copy the citation in a suitable style. There are five most common citation styles available, including APA.
To evaluate the impact of founded articles pay attention to cited by link. Google Scholar lists each article and the number of times it has been cited in other articles. Click cited by link to read them.
Another way of discovering publications about your chosen topic is to look at related articles. Related articles list closely related articles to your chosen one.

Although Google Scholar lists also books (marked as [BOOK]), in most cases in fact they are book previews and some pages are omitted. Those previews can still be helpful, by some books whole chapters are available.
