The Shapiro Wing is now open for silent study. We look forward to welcoming you back into the Library. For more information about study space and resources available, please see our On-Campus Services Page
Choosing a topic - where do you begin?
Many students choose a topic that they already know something about and explore new research in that area. Whatever you choose, make sure you are interested in the topic! If you don't have an idea yet, browsing through the library's book collection in biology will present you with a broad variety of subjects. You might also want to scan issues of the magazines Discover, New Scientist, BBC Knowledge, or Science to read about topics in the recent news.
Too big or too little?
A quick way to get a feel for how well your area has been researched is to run a search in Google Scholar. If only 10 hits are returned you'll know you have to expand your topic or change your topic. There just isn't enough information. On the other hand, if you get 10,000 hits you'll know you have to narrow down your topic. Google Scholar also has a link at the top of the results list to limit results by date.
If a book or article you want is not available, use Interlibrary Loan (ILL). The Library can order books and articles from other libraries. This process takes few days but is completely free for DelVal students, faculty, and staff.
If you have answered "yes" to these five questions you have probably located a scientific article.
Research articles are also often known as scientific or peer-reviewed articles. If the article is NOT written by the person or group who did the research, it is NOT a peer-reviewed or scientific article. Research articles are important for knowing what new discoveries have been made. This is why it is important to use recent articles, since they will be the first things published on a new scientific development.
Here's a quick overview of how to identify these journal articles:
Assessing the effectiveness of Garcinia cambogia for weight loss
BY 4110 - Senior Seminar
September 13, 2021
When the author's name appears in the sentence, it does not need to be repeated in the citation.
Recent literature has examined long-run price drifts following initial public offerings and other factors (Ritter 2009).
Fisher (2010) reaches more or less the same conclusion.
More than one author
(Smith and Johnson 1998)
More than two authors
(Smith et al. 2001)
Multiple citations in the same sentence
When referencing multiple studies within the same sentence, cite in order by author's last name
(Dawson J 2006; Mondari 2010)
Use the first word or first few words of the title. Use only as many words as are needed to distinguish it from other references.
(Handbook ... 2000)
To save space, journal titles are abbreviated according to the ISO 4 standard, shortening significant words and omitting insignificant words.
NOTE: There is another abbreviation generation CASSI which can also be used. It does not follow CSE so remember to make the appropriate adjustments.
Last name First initial. Year. Article title, sentence style capitalization. Abbreviated journal title. Volume(issue, if available):pages. URL, if no DOI available.
Lawskowski DA. 2002. Physical and chemical proprieties of pyrethroids. Rev Environ Contam Toxiocol. 174:149-170. doi:10.1136/rect.330.7500.1119.
Article titles are not italicized. However, species names are italicized and capitalized normally.
In vitro and in vivo reconstitution of the cadherin-catenin-actin complex from Caenorhabditis elegans.
NOTE: As many more journals only publish online, they often don't have page numbers. They will usually have a article number which sometimes has an "e" before it, for example, "e586839." You would use this in place of the page range.
Journal article with multiple authors
When there are 2 to 10 authors, list all of them. If there are more than 10 authors, list the first 10 followed by et al.

CSE recommends placing reference to personal communications such as letters and conversations with the running text, not as formal end references. The nature and the source of the cited information should be identified by an appropriate statement. Place the source information within parentheses, using a term or terms to indicate clearly that the citation is not represented in the reference list.
...and most of these meningiomas proved to be inoperable (2003 letter from RS Grant to me; unreferenced, see "Notes") while a few were not.
The author must provide written permission to the publisher from the cited person (if living) or from the cited organization if it is carried in a document such as an internal memorandum that is not accessible to scholars. The permission should be acknowledged in an "Acknowledgements" or a "Notes" section that follows the text of an article or is placed at the end of a book's main text; such statements may include additional details such as the reason for the communication.
