Perhaps you know that Arthur Kellermann writes articles about emergency medicine. Or you saw a great article on breastfeeding, but all you copied down was the author’s name. Or you want to see if your professor ever publishes anything.
Virtually every database and index has some provision for searching for works written by a particular author. Usually it’s a fairly straightforward process. The database should either have an input box marked “author,” or a generic input box and a way to limit the search to the “author” field.
International Pharmaceutical Abstracts (IPA) and PubMed use generic fields with drop-down menus that allow you to limit the search to “author.” Medline (EBSCO) uses generic field with either tags (au) or drop down boxes to limit to author.
Although different databases expect you to enter the author’s name in different ways, you’re generally safe just using the last name. If the last name is common, you’ll want to add a first and (if you know it) second initial. Thus, if you’re looking for articles by Arthur Kellermann, you could use:
A scholarly journal is different from a magazine or other periodical because it’s a respected forum in which scholars share their research. The articles in journals are usually peer reviewed, and can be taken as legitimate scholarly knowledge.
If you take a side-by-side look at Molecular Microbiology and Time Magazine , you’ll spot the differences pretty quickly.
Easy. Maybe you know that Cell is a highly-respected journal and you want to see some articles from it, or you heard on the radio about a new study in the New England Journal of Medicine. Either way, virtually all databases allow you to search for articles using some or all of the words in a journal’s title.
Depending on the database you’re using, you’ll either have a text box labeled something like “journal title,” “source title,” or “source publication,” or you’ll have a generic text box which you can limit using drop-down menus. Just type in a journal’s name, and run the search.
Of course, if you just search on the title of the journal, you’ll get back every single article from that journal that the database contains. Searching Web of Science for “Nature Cell Biology” gets 1,395 articles. It would take you days to wade through that. But since you’re probably interested in articles on a specific topic or by a specific author, you can go ahead and add “Liu” as the author, or “telomeres” as the topic, and you’re down to a manageable number (if you add both, you’re down to a single article. That’s the power of limiting your search).
First of all, you have to know if you're after a research article, or a review article. Once you know that, most databases and indexes are set up to allow you to do choose a topic and find articles on that topic. All you have to do is pick some words that describe the topic of the articles you want to find, and the database looks for articles on those topics.
The words that you choose to describe your topic are called "search terms." The database will try to find your search terms in the most important fields of each article. That is, if you run a search on "cows," the database will look for articles that have the word "cows" in the article title, the author, the journal title, or the abstract (summary) of the article. Sometimes this is referred to as "text word" searching, because the database is just looking the text of your search term to appear anywhere important.
Once you've chosen good search terms, just type them into the text box marked "subject," "topic," or "keywords." Some databases only have one text box to use. Type in your search terms and click the "go" or "search" button.
Here are some examples of good keywords:
