These tools will help you to either locate items in our collection (DOI Search, Journal Finder, LibKey Nomad) or to request a copy of an item we don't currently have access to (Interlibrary Loan).
To get the most out of your searches in library and public databases (or even Google!), it helps to know how to search using keywords and operators. Instead of trying to use full sentences, select the most important terms in your query (usually nouns or noun phrases) and join them to other terms in order to control the results you get. For example: if you're trying to learn about craniofacial surgery, you'll get the same or better results in PubMed using the phrase "craniofacial surgery" rather than "what is craniofacial surgery." Here are some ways to use and combine terms to get better results (links go to illustrative search results in PubMed):
Example: Use "craniofacial surgery" instead of craniofacial surgery. Notice that using quotation marks generates a much smaller and more focused set of results.
Example: Instead of doing two separate searches for "green tea" and "black tea", combine them: "green tea" AND "black tea" [Note: PubMed and some other databases assume that any terms you enter in the search box are joined by an AND unless you ask them to do otherwise]
Example: Heart attacks can be described in different language depending on context and usage. You'll get different results searching for "heart attack" than you would searching for "myocardial infarction". Using OR, you can combine them to cover both options, like so: "heart attack" OR "myocardial infarction". This is also a good trick to use to cover variant spellings (UK vs US English), plurals, and other forms of words.
Example: Sometimes, your search will include results that aren't quite what you need. You can use NOT to get rid of them. To test this, first look at this search for "oral health", then compare it to the number of results and visible options in this search for "oral health" NOT pregnancy
The Threadbox below contains three basic instructional VoiceThreads for using PubMed. If your view in the box is too small, here are some individual links so you can open each one in a new window:

Include the Peer Review table and the rest of the Peer Review FAQ here. Consider adding some guidance for where to look to see if something is peer reviewed. Pull code from RADT424 guide.
As a general rule, evidence is stronger if it is more generalizable and less vulnerable to bias. Generalizability is easier to get from the combined analysis of several studies than it is from any single study. Rigorously designed and controlled experimental studies are typically less vulnerable to bias than purely observational studies, which are in turn less vulnerable to bias than descriptive or qualitative studies. Expert opinion or analysis pieces, no matter how well-sourced and well-informed, are the weakest form of relevant evidence, as they do not lend themselves to generalization well and often reflect the biases, agendas, or prior assumptions of their authors.
Note that for the purpose of your work in Dental Hygiene at USI, animal and laboratory studies typically don't constitute usable evidence.

Format for organizational and government reports varies widely – especially if you wander into the world of numbered codes and resolutions. In these cases, use your best judgment, consult the AMA manual online (see Chapter 3, sections 3.13.2 and 3.15.5), or (if needed) reach out to a librarian for assistance.

Chances are you will most likely be citing online news sources. If this is the case, you will often not see a “section” or page numbers because news publishers reformat content for online environments and remove things like page numbers - which would mean nothing to online readers. However, if you do see this information online, include it! Additionally, if you are citing a print newspaper – or a PDF of an old print newspaper in a database, this is important information to include.

Discussion
1. If the author of the chapter cited is also the editor of the book, omit editor information.
2. To cite a book as a whole, rather than referring to an individual chapter or specific pages, do this: Author(s). Book Title. Edition. Publisher; year of publication. Accessed date (if online/ebook). URL (if online/ebook)
3. No edition number is needed for the first edition of a text.
Author. Title or brief description.; year published. Accessed date. URL

Presentations made in class can be a little tricky; AMA is not a student-oriented style, and does not have a special format for class presentation citations. The example presented here is a local practice at USI, and does not represent any official position presented in the manual itself. The best place to look in the manual for assistance is 3.13.9.1: Items Presented at a Meeting. For most of the presentations made in classes at USI, even if there are videos or slides shared in BlackBoard, you're better off omitting a URL (as you won't be able to provide one that works for all users).
For most serious research work done in CNHP programs at USI, Continuing Education materials are not appropriate sources. That said, occasionally a student may find them useful for background information. We offer two models here, depending on how the material in question is published. The models suggested here are local to USI -- the AMA Manual itself does not specifically address them.
Continuing education content published by a company called StatPearls frequently turns up in PubMed search results, and it is typically classified by its metadata in PubMed's database as a book. For the sake of simplicity, a slightly modified book/monograph model generally works best for StatPearls content. Typically, the publication date is actually the last date this content was updated. Other continuing education materials may also appear in this "book" format, but the most commonly seen in PubMed is published by StatPearls; obviously, if it's published by someone else but still functions like a book, replace "StatPearls" with the appropriate publication information.

Companies like NetCE offer a wide range of continuing education courses for healthcare professionals. You may come across older/expired course content elsewhere, but the current, up to date material is only available from NetCE's own site. NetCE and other providers often offer course materials in both plain webpage and ebook formats. If you have NetCE content in ebook format (as a pdf or epub document, for example), use the book model we used for StatPearls above, with NetCE as the publisher and the listed course faculty (look toward the end of the document) as the authors. Treat the release date as the publication date.
Otherwise, cite NetCE like an authored webpage on a website:
