There are 4 basic parts of a citation:
A citation or reference includes all the information needed for someone to identify and find the resource. Elements will change depending on the resource (a blog, article, legal materials, etc.). Depending on the citation style, a citation may include any of the following: title, author, date, page numbers, publisher, place of publication, link, doi, etc.
Journal article with a DOI (Don't know what a DOI is? Find the answer here.)

You may need to use a direct quote from an e-book, websites and webpages, or other material that do not have page numbers. When there are no page numbers provided, the in-text citation must still indicate where in the text the quote can be located. Any of the following approaches is acceptable; use the approach that will best help readers find the quotation:
EasyBib's barcode scanner pulls citation information and formats it in APA, MLA or Chicago style. You can then e-mail the citation to yourself to copy and paste into your reference list. Available for iOS, Android, and Google Apps.

There are 4 important components of any citation: author, year, title, and source (site name/URL). To cite websites, the most important components are the author (whether an individual or institution), the date, the title of the page, and the url for the site.

References for letters in a digital repository may be formatted using the template shown in Section 10.8 of the seventh edition of the Publication Manual. A letter is not likely to have a title, so you can substitute in a description in brackets in the title position. The best example to follow is actually Example 95 on page 346, a radio interview recording in a digital archive, although Example 73, an informal work from an institutional repository, also provides an idea of what the reference would look like.

Alternatively, if you think using the title assigned by the library would aid in retrieval, you could put the library's title in the title position instead of the description. Because the library's title identifies the source as being a letter, you do not need to add [Letter] after the title.

For most guidelines posted through AHRQ and National Guideline Clearinghouse (guideline.gov) you will cite these documents like websites and web reports. In other words, you need the same 4 major components discussed earlier on this page: author, year, title, and source. After the title of the work, provide any number or identifier for the standard (if any) in parentheses without italics. Below is an example of a guideline found on Guideline.gov:

Guidelines published in a traditional journal, whether in print or online, should be cited as journal articles.

Sometimes you will use a website which allows you to select and compare data. These might be sites from the Census, the CDC, or a site like Nursing Home Compare from the Centers for Medicare and Medicaid Services. Purdue's OWL site for APA offers recommendations for citing data sets and graphic data. We recommend you combine pieces of these two formats to cite a resource like Nursing Home Compare. This allows you to credit the source and provide your reader with the information needed to retrieve the data you used.

One-author entries should be arranged by year, the earliest being first. No-date (n.d.) references precede references with dates, and in-press references are listed last.
One author entries precede multiple author entries beginning with the same first name author, even if the multiple-author work was published earlier.
Multiple-author entries in which all authors appear in the same order should then be arranged by the year of publication. Multiple-author entries with the same first author and different subsequent authors are arranged alphabetically by the surname of the second author, then third, and so forth.
Some confusing and ambiguity may arise for works with same author(s) and dates. To distinguish between these works, put a lowercase letter after the year in both the in-text citation and the reference list.
Assigning letters is a two-step process. First, compare dates. References with only a year preceded those with more specific dates, and specific dates are placed in chronological order.
Second, if the references have identical dates, alphabetize the references by title (disregarding the words "A," An," & "The" at the beginning of the reference title).
