Library Resources for Nutrition 403

Learning Goals

1. Be able to form complex searches in order to effectively search for articles.
2. You should come out of this session with a head start on your research.

Research Question into Search Statement

A walnut based poppy seed salad dressing may be the most acceptable consumer product because of walnut oil’s lower acidity and rounder flavor profile compared to other commonly consumed nut oils.

1. Identify the main idea and supporting ideas. A simple search uses the connector and: main idea AND supporting idea
2. Start a list of synonyms, examples, and categories for the main idea and the supporting idea. If you don't get enough results in your first search, try the synonyms instead.
3. Add to the list as you review the literature.

Background Information

Google
Be careful not to spend too much time wading through lots of results OR base your work on biased, inaccurate, or outdated Web sources.

Library Catalog
Books can offer great background information. Books on food analysis, the science behind food preparation, reference works, and many cookbooks (including classics) can be found in Jackson Library after call number TX 541.

Netlibrary e-books
The advanced search accepts quotes, and, or, and truncation. **Create a free account (top right) before you try to use off-campus** Another caveat-the same book can only be used by one person at a time.

Examples of handy print books:
Encyclopedia of Food Sciences and Nutrition. Jackson Library Reference Room (can't be checked out), TX 349.E47.2003. Ten volumes of useful essays on nutrition and food science topics. Start with the index in volume 10.

On food and cooking : the science and lore of the kitchen. TX651 .M27. Excellent introduction to the science behind many culinary topics.

Food lover's companion : comprehensive definitions of over 3000 food, wine, and culinary terms. TX349 .H533 1990. Definitions, brief descriptions, and proper spellings for many culinary topics.

Finding Journal Articles

Science Direct Full text of Elsevier journals in many disciplines (lots of science but some health science content). Accepts Boolean connectors, truncation *, to narrow your search you can force a phrased search by putting quotes around "your terms."

Pros: Full text, science content

Cons: No subject headings to help you find other records based on a useful result. Won't email full text.

Searching: To see more search options, hit Search button in the green bar across the top

Web of Science (1955-present) Science and social science citation index. Accepts Boolean connectors, truncation *, "force a phrased search with quotes"

Pros: High quality scientific content, lots of indexing to help boost your search power.

Cons: Little or no full text. Does have Journal Finder links, which allow you to search our journal subscriptions to find out whether we own the articles you've identified.

Searching:

1. Hit the General Search button
2. Try a topic such as walnut oil
3. Too many results? "Search within" (top right) to refine: flavor

Hint: "walnut oil" will find my terms together

Getting article full text: Follow Journal Finder link IF there is no "Full Text" button below the citation

Agricola via the National Agricultural Library (1970 - present) Provides citations to articles on all aspects of agriculture, including nutrition, chemistry, etc. Searchable through FirstSearch or through National Agricultural Library interface. Accepts Boolean connectors and truncation *

SciFinder Scholar (1907-present (articles and patents); 1955-present (substances)) Online version of Chemical Abstracts. Users must create their own guest user name and password. Access limited to 8 concurrent users.

Other nutrition databases

Google Scholar Guide to scholarly literature on the Web.

Pros: Interdisciplinary; "crawls" full text of articles behind many publisher subscription barriers; you can set it to show Journal Finder links next to citations

Cons: Citations often incomplete which can make it harder to find full text when not available; Fewer search limits than subscription databases; More need to evaluate appropriateness of sources
