Google Scholar will allow you to add citations to Endnote Basic, as well as to other citation managers. Once you have done a search and have citations in front of you, you'll see that there is a "Cite" link at the foot of the reference. When you click on that link, you will be offered three versions of the citation which could be copied and pasted, but there are also links in the bottom edge of the box that show BibTex, RefMan, and EndNote, among others. Click on the name of the product you use, and then log in as needed, and the citation should be imported into your list of references.
Web-based Citation Managers:
EndNote Basic allows you to save citations to a personal database and then format those citations in footnotes, endnotes, or bibliographies. It is available through Web of Science.
Zotero and Mendeley are two of the free citation managers that are commonly used in academic circles; we don't have formalized support for them, but they have help pages and your librarian may be using one or more of them. Several browsers have plugins that work with Zotero or Mendeley.
Plagiarism and academic dishonesty go beyond simply cutting and pasting text from an article or book into your paper without attribution; they can include paraphrasing without attribution or listing sources that you have not consulted in your Works Cited list. The consequences of plagiarizing another's work can be very serious. Citing your sources is the first step to avoiding plagiarism.
Many databases provided by the libraries have a "Cite" feature built in. When you are looking at the detailed information for an item, look for a link or button for citing. If available, click on it; a pop-up screen will show citations in various styles that you can cut and paste into your bibliography.
Various disciplines differ in what style they prefer. Journal citation styles may be required. Endnote Basic and other citation managers include many of the journal-specific styles. Ask your professor if you have questions about what style to use.
