Library Search searches scholarly, trade, and popular publications. In many academic assignments, you will be encouraged to primarily gather sources from scholarly publications. For your Persuasive Speech, you can use all three types.
Always check with your instructor to see which types of publications you can use for your assignments!
When doing research, you will come across three main types of articles: Scholarly, Trade, and Popular. There is a time and place for each type of article.

Sources can be described as primary, secondary, and tertiary. These categories describe how many layers of interpretation a source has.*
Click the tabs at the top of this box to learn about each layer of interpretation.
*Many sources will have a combination of primary and secondary source information. It is rare to find raw information without any interpretation accompanying it.
A primary source is raw information. This can look differently depending on the discipline. In the sciences, raw information could be a data set; in the humanities, raw information could be the piece of art, a manuscript, or sound recording; in the social science, raw information could be a diary, newspaper clippings of an event, or census data.
Primary sources contain the information that is the focus of your research.
While the databases listed below can be used to find primary sources for a variety of topics, some disciplines have specific collections. See a subject guide for more resources.

A collection of primary source exhibits for students and scholars of queer history and culture. The database uses "queer" in its most inclusive sense, to embrace topics that are gay, lesbian, bisexual, and transgender and includes work on sexual and gender formations that are queer but not necessarily LGBT. Each document collection in the database includes a critical introductory essay that helps explain the significance of the primary sources in historical terms and in relation to previous scholarship.

Secondary sources are interpretations of raw information. They may or may not contain the raw data. For example, an anthology of letters written by a historical figure can contain the primary source of photographs or transcriptions of the original letters and be accompanied by the secondary source of short essays that provide context for the letters. Most books and journal articles will fall into this category.
Secondary sources provide context for the information at the focus of your research.
While the databases listed below can be used to find secondary sources for a variety of topics, some disciplines have specific databases or collections. See a subject guide for more resources.
This is a multi-disciplinary, full-text database which includes 4,000 peer-reviewed journals and indexing and abstracts for more than 9,000 journals.
ProQuest Central currently includes all the content available in these ProQuest Databases:
Tertiary sources are collections of interpretations (secondary sources). Like secondary sources, they may contain parts of primary sources but the purpose of a tertiary source is to give a broad overview of the scholarly conversations around a primary source. These are typically referred to as reference sources like dictionaries, encyclopedias, bibliographies, textbooks, handbooks, literature reviews, etc.
Use tertiary sources to start your research.
While the databases listed below can be used to find tertiary sources for a variety of topics, some disciplines have specific books or databases. See a subject guide for more resources.
