database research- A path to success
i can access the maine east library website
And maybe find the page for my class assignment.
i can find and choose a good database for my research needs
Think about:
  • The research topic
  • Where you are at in your research.
  • What type of information do you need? Are you in search of primary sources, background information, or something else?
I can log in to access databases with my username and password
USERNAME: Your email without @s207.org
Password:​ Your email password
i can craft a good search that finds useful results
  • I can identify the important keywords and search terms for my research.
  • I can use the advanced search, and choose the best field to search for my terms in.
    • Fields can include Title, Subject, Abstract/Summary, or Anywhere/Keyword.
  • I use quotation marks around important phrases. (But only ​around important phrases.)
  • If I don't find good results the first time, I refine my search and try again.
I can filter my search results to find the most useful resources
Some filters include:
  • ​Publication date
  • The type of source or publication (newspaper, journal article, images, etc.)
  • If the source is peer reviewed
i can evaluate my search results to choose quality resources
Evaluate sources by these criteria:
  • Currency: How timely is the resource and the information within it?
  • Authority: How reliable are the author and publisher on the topic?
  • Accuracy:  How reliable is the information presented in the resource?
  • Relevance: How important and valuable is the resource for your research needs?
  • Purpose: What is the reason the resource exists? How objective is it?  What points of view are included or excluded?
I can use the tools within the database resource
Some tools might include
  • Creating or exporting citations
  • Saving the source to your Google Drive account
  • Downloading a PDF of the source
  • Translating the source into other languages
If you find yourself struggling with any of the steps in this process, look for more help in the other sections on this page.
​
You can also email or chat Ms. Cochran or Mr. Mather for further help.
​​​SEARCH STRATEGIES
Search Terms & Fields
The words you search for, how you phrase them, and where in the resource you are looking for those words, are key to finding the best resources.
Terms
​The actual words you are looking for.
PROTIP: 
Use quotation marks to search for specific words together in a specific order
​"Declaration of Independence"
"Civil Rights"
"Chicago Fire"
Field
Where are you looking for your search terms?
Title: Name of the source
Author:  Who created the source
Subject: What the source is about
Abstract: Short summary of the source
Keyword: Searches all key fields at once
Anywhere: Searches the entire source
Boolean Operators
Refine and fine-tune your search by combining search terms & fields. Some operators narrow your search, and others broaden your search results.
AND
Results with search terms combined.
Lincoln AND "civil rights"
poverty AND ​crime
OR
Results with any of the search terms.
"right to vote" OR ​suffrage
wage OR ​income
(Great for synonyms and ideas with many different names.)
NOT
Results with search terms ​excluded.
"Chicago Fire" NOT soccer
dementia NOT ​Alzheimer's
(Great for targeting a term that has many different meanings.)
filters & limit search results
After you perform a search, you can sort and fine-tune the results using filters or limiters. Different databases may use different terms, but most will let you filter by the categories listed here.
Subject
What topics the resource covers​
Hone in on all of the resources related to a topic. Databases often have specific, controlled vocabulary for topics.
​​"Canines" instead of "dogs";  "hypertension" instead of "high blood pressure." 

Search multiple subject terms at once using Boolean Operators to get even more specific.

​​You can find a database's specific subject terms  linked in a resource's information page, or in a database's Thesaurus Terms. Use those terms to search in the Subject field on future searches.
Peer Reviewed — Limits to items from scholarly journals that have gone through a review process by experts in the field.​
Publication Date
​When the resource was created
Limit the results to recent years for the most up-to-date information and research.
​
Older results can help find primary sources or show how people in certain time periods understood your topic.
Source/Content Type
​Where the resource was originally published
Reference
Books of facts with specific entries to cover particular information, like encyclopedias, atlases, dictionaries, etc.
(Ex. Dictionary of American History, Encyclopedia of Crime and Justice)

Newspaper/Magazine/Periodical
Often shorter articles, for the public and a general audience. Great for overviews, recent news, and opinions about a topic.
(Ex. Rolling Stone, Chicago Tribune)

Academic/Scholarly/Trade Journal
More technical articles for a more specialized audience. Often longer articles that include actual studies and research conducted on a particular topic.
(Ex. Journal of Education, American Historical Review)
Full Text
If the entire resource can be viewed and accessed on the database
Some databases just include information and a citation for the resource, but not the actual resource itself. Limiting by "Full Text" excludes those from your search results.
​
If you see a citation for a resource that you would like to find, talk to the librarians. We can often get that resource for you in just a few days!
Database PRO-tips
Library databases and other research sources have these tools you can find and use to research more effectively and efficiently. 
Search multiple databases. Each database has a different collection of resources. Performing the same search will get you even more resources to choose from. 
​Use the citations and bibliographies of the most useful resources. Search for those authors, or even those exact resources. Find the information those ​writers used. 
See also: Trace information back to its original context from the S.I.F.T method under "News & Media Literacy."
Cite resources on any of our databases by finding the quotation mark icon.  
Choose the citation format that is required for your project.
Abstracts are short summaries of there resource. Read the abstract and subject terms to decide if you want to save the resource and explore it further. This will save you a lot of time!
evaluating resources
Currency
Timeliness of the information
  • When was this resource created? Has it been updated?​
  • If it is a website, do most of the links still work?
  • Does your research topic require your information to be the most recent, or will older resources still be valuable?​
Authority
How reliable the source of the information is
  • Is the author clear and easy to find? Are their background and credentials clearly stated?
  • Do they have expertise or experience related to the topic?
  • Who is the publisher? Are they well known and trustworthy?​
  • Use lateral reading to find more background information.
Accuracy
How reliable and correct the resource is
  • Are the arguments and claims supported by evidence?
  • Can you verify the information from multiple other sources?
  • Does this resource have citations, footnotes, or links?
  • Has the resource gone through the peer review process?
  • Are there any spelling errors or typos?
Relevance
Importance of the information for your needs
  • ​Does the information help answer your research question?
  • Is the entire resource related to your topic, or only parts of it?
  • Does the information support or contradict your other sources?
  • Does the resource provide a perspective or point of view on your topic that is absent in your other sources?​
  • Is the information presented in a way that is too simple, too technical, or too advanced for your needs?
Purpose
The reason the resource exists
  • Why was the resource created? Is it presenting straight facts and data, or interpretations and opinions?
  • Is the information presented objectively, or is it written using words that arouse emotions? Is it attempting to sway the audience toward a specific point of view?
  • Is the resource upfront about having a particular viewpoint or mission?
  • How is the work funded? Is there extensive advertising on the website? Is a subscription required to access the information? Is the research funded by an organization with a specific interest?
CITATION TOOLS
​NoodleTools provides integrated tools for citations, document archiving, annotation, and collaborative research and writing. Most library databases will create properly formatted citations and export it right to your NoodleTools project folder.
Google Docs has a built-in Citation Tool to help you format citations, create a bibliography/works cited page, add footnotes, and more. Watch a tutorial here.
The Online Writing Lab (O.W.L) at Purdue University is an extensive resource for creating works cited and annotated bibliographies, as well as help with research, writing, and formatting styles. 
​primary sources
Types of Sources

All materials, data, and information used in research are known as sources. Information sources are classified into three categories: Primary, Secondary, and Tertiary Sources.
Primary Sources are original materials that provide first-hand information or data. They serve as the raw materials used as the building blocks of research by historians, scientists, and other scholars. Determining if a source is primary depends on context, which will be discussed further, but include examples listed here.
Examples:
  • ​Photographs
  • Music & video recordings
  • Interviews
  • Speeches​

  • Newspapers & periodicals
  • Census data & survey results
  • Letters, diaries, and journals
  • ​Scientific & medical study data
Secondary Sources describe, digest, interpret, evaluate, and analyze information, usually by using multiple primary sources. 
Examples:
  • ​Journal articles
  • Biographies
  • Nonfiction books​

  • Reviews & criticism
  • ​Documentary films
Tertiary Sources compile, list, index, and summarize information from secondary and primary sources. These sources are great for starting your research journey when getting background information, but are not sources you want to cite in your own research projects.
Examples: 
  • Encyclopedias
  • Reference books​ ​

  • ​Wikipedia
  • Textbooks​ ​
Identifying Primary Sources

Determining if something is a primary source is often dependent on the context in which the source was created and published, and how you are using and interpreting the source. Consider these factors when making a decision.
Timing

Was the source produced at the time of the event/period being studied? Shortly after? Or much later?

Sources created closer to the event are more likely to be primary.
Primary Source: A photograph of settlers preparing for their journey on the Oregon Trail in 1847
​
Secondary Source: A 2018 documentary film about the Oregon Trail using photographs, diaries, and other source material 
Authorship

Was the source created by someone directly involved or witnessing the event?

First-hand accounts and records usually indicate a primary source.
Primary Source: A memoir written by a woman who grew up during the Great Depression

Secondary Source: A biography by a historian published in 2004 about Frances Perkins, the U.S. Secretary of Labor during the Great Depression 
Purpose

Is the source's original purpose to convey direct information, or to analyze or interpret the information?

Raw documentation and data tends to be primary sources
Primary Source: Statistical data on 1980s voter turnout collected by the U.S. Census Bureau
​
Secondary Source: An article in an academic journal analyzing voter trends over time that uses census data
Context of Use

The context in which a researcher uses and analyzes a source can also determine if it is primary or secondary.

If the source directly provides the key information or evidence being examined, it is likely a primary source.
Source: Review of the movie Jurassic Park by movie critic Roger Ebert.

Primary Source: For a biography about Ebert, or a study of film criticism through history. 

Secondary Source: For research on the evolution of special effects in movies, or a biography of the director.
Finding Primary Sources

There are multiple ways to gather Primary Sources. Think about the type of primary source you are looking for to help you decide the best place to find it.
Databases & Websites
Several databases and websites are dedicated to providing original documents, raw research data, and other primary sources. You can find a large collection of them on our Primary Sources database page.
Archives
Archives are collections of historical artifacts like documents, records, manuscripts, or photographs surrounding a specific place, institution, individual, or group of people. They are usually hosted by museums, historical societies, libraries, businesses, universities, and other institutions. Many archives require appointments and other requirements to view their materials, but there are often partial or complete digital archives as well.
Oral Histories
Oral histories are collections of interviews - either audio recording or transcribed - with people who have first-hand experience with a historical event or topic. Oral histories are often collected in books or as digital archives. 
Create Them Yourself
Conduct interviews or surveys, collect your own raw data, or take your own photos! If they help to answer your research question, they are primary sources.
​news & mEDIA LITERACY​
How do you know if news and other online information is credible?

Use the four moves of the S.I.F.T. method to help you analyze news, videos, and other information that you encounter online and on social media.
The SIFT method is a strategy developed by digital literacy expert, Mike Caulfield. All SIFT information on this page is adapted from his materials with a CC BY 4.0 license.
Stop
Don't rush to share and trust information right away!
Consider what you already know about the topic or source. Is it reputable and reliable?

Focus on why this information matters to you. Don't get distracted by unrelated details.

​Recognize if the headline/article/video is trying to provoke a strong reaction to get attention. Is their goal to get more views and clicks over sharing accurate information?
Investigate the source
Research the author and publication
What relevant background, expertise, or agendas to they have?

Use lateral reading: check what other credible and trusted sources say about this source, instead of relying on how they present themselves. Wikipedia and Google are great.

Is the site, author, or organization what you originally thought it was? Is there inconsistency in how they present themselves?
Find additional coverage
Find the best information on the topic.
Search for other coverage of the topic to compare perspectives. Do different sources agree or contradict the original information? Is there a general consensus?

Read more in-depth reporting and analysis - don't settle for the first article you see.

Evaluate which sources seem the most thorough and credible. Consider adding them to your personal list of trustworthy news outlets to check first in the future.
Trace information to its original context
Find the original source for the claim, quote, and media.​
It's always best to locate the origins of images, videos, quotes, research studies, and other information.

Check if re-reported information accurately reflects the primary source.

Has anything been altered or taken out of context. Was data cherry-picked to support a specific agenda? 
When in doubt, contact an expert - like a librarian!
