18 See SciFinder Scholar Help and also Search Hints Help Tips for Specifying a Research Topic Restrictions Up to 40 words can be used to define the research topic. Up to seven concepts can be used to define the research topic. Up to eight terms can be used to define a single concept. Up to three Boolean operators can be used to define a single concept. Use of AND and OR Sometimes, SciFinder cannot discern the differences in the words AND and OR. In these cases, SciFinder runs the search using AND and OR and presents both results for your selection. Do not use the word AND if a preposition would be more exact. Instead of: human growth hormone and fetal development Use: effects of human growth hormone on fetal development Do not use AND when you really mean OR. Use OR to signify either term or both terms. Use AND to signify both terms only. Example: interface software for bibliographic information AND numeric data Meaning: You want a single piece of software to interface with bibliographic information and numeric data. Example: interface software for bibliographic information OR numeric data Meaning: You want a single piece of software to interface with bibliographic information or numeric data. 18

19 See SciFinder Scholar Help and also Search Hints Help Tips for Specifying a Research Topic Negation You may describe a research topic using negative terms such as NOT or EXCEPT (in either upper- or lowercase). Example: ringed planets but NOT Saturn Abbreviations and Misspellings SciFinder is designed to recognize and accept: Commonly used abbreviations, such as BTU and Prep Words spelled according to either British or American English (colour or color) Synonyms You may enter synonyms with your research topic. Place synonyms in parentheses next to the topic you entered. Example: milk production of cows (bovines) Result: SciFinder searches for both terms, cows and bovines. Truncated Words and Truncating Symbols SciFinder automatically truncates the terms in your query and searches for plural forms, past tense verbs, and other word forms. Do not include truncation or wildcard symbols (such as! or *) in your search terms. SciFinder disregards them and interprets the remaining characters literally. Example: effects of age on calcium absorption in women Result: SciFinder automatically expands your query to include terms such as aged or 19aging.

20 URLs for selected Library databases may change Have you experienced issues trying to access databases through the Georgia Tech Library website? It is likely due to our recent change to OpenAthens IP Authentication. If you have any access questions or database access problems, please contact This will allow us to establish an issues log and address the access issues systemically. Authentication service information is at including changing permanently linked information ("Recent News" - right column: OpenAthens; Experiencing Issues with databases, etc.). While accessing e-resources off-campus, you may notice an OpenAthens login screen. The OpenAthens screen will ask you to identify your home. Use the "Login via your institution: Other Institution Login" (box, right column of screen) then "Find your organization" to search for Georgia (Georgia Institute of Technology). See example. From there, use the Georgia Tech login service and you will be given access to the resource. All Library databases: 20 Library home page (left column): "Research Tools" -- "Find Databases"
