To locate books on specific topics in the library catalog begin with a keyword search, which allows the use of everyday terminology and the combination of two or more concepts (e.g. "food safety and packaging"; "pesticide residues and food"). Click on a title of interest and follow the subject links in the catalog record to locate other books on the same topic. Use the truncation symbol * to retrieve alternate forms of a word (e.g., food contamina* will find food contamination, food contaminants; food label* will find food label, food labels, food labelling).
Alternatively, you can do a subject search instead of a keyword search. Subject searches are more precise, but require the use of the standardized Library of Congress subject headings assigned by catalogers. Some of the official Library of Congress subject headings used in this area are:
FOOD ADULTERATION AND INSPECTION
PESTICIDE RESIDUES IN FOOD
RADIATION PRESERVATION OF FOOD
RADIOACTIVE CONTAMINATION OF FOOD
You can search the catalog for Electronic Materials to limit your results to online resources only. To find resources by topic, click Keyword or Subject, enter your search terms, and click the Search button. You will retrieve a list of electronic resources, ranked by relevancy and displayed 50 per screen, with the most recent listed first. Click on a title of interest for further information and hyperlink.
There are also guides to electronic books in both human and veterinary medicine that list select titles alphabetically, arranged by subject. These may be helpful to consult if you are looking for a specific topic.
