Most important, provide the full URL to the resource, including the protocol, host address, and the complete path or directories necessary to access the document. (best to use an electronic "copy" from the "location" box of your browser and "paste" into your word processor).
Citations to appropriate sources show that you've done your homework and are aware of the background and context into which your work fits, and they help lend validity to your arguments.
Reference citations also provide avenues for interested readers to follow up on aspects of your work -- they help weave the web of science.
Science moves forward only by building upon the work of others.
There are, however, other reasons for citing references in scientific research papers.
If you have more than one entry by the same author, they should be further ordered by increasing publication date (more recent papers last).
If you have multiple sources from a single author published in the same year, distinguish them both in the in-text citation and in the reference list, by appending the letters a, b, c...Reference lists are generally reverse-indented--this just helps the reader to find references to specific authors that much faster. Follow the examples given below and you will be all set. Sources that need to be acknowledged are not limited to books and journal articles, but include internet sites, computer software, written and e-mail correspondence, even verbal conversations with other people (in person or by telephone).All different kinds of sources must be acknowledged.Furthermore, if you use figures, illustrations, or graphical material, either directly or in modified form, that you did not yourself create or design, you need to acknowledge the sources of those figures.When you cite a reference in your text you should use one of the following three formats: (1) Mention the author by last name in the sentence and then give the year of the publication in parenthesis: You only need to include the page number in the citation if you are quoting directly, or if the source is very long and the specific fact or idea you are citing can only be found on a specific page.Your list of References Cited should include all of the references you cited in your paper, and no more!It should be arranged in alphabetical order by the last name of the first author.Harnack & Kleppinger (2000) have adapted "CBE style" to cite and document online sources.You should acknowledge a source any time (and every time) you use a fact or an idea that you obtained from that source.
