Information obtained from full-text electronic resources should be cited in bibliographies and notes just as print sources are cited. If the electronic source does not have page numbers, don't invent them: omit them, giving the author's last name in the parentheses and some other indication of location. The usual substitute is to use "access points" like absolute paragraph numbers (you have to count them yourself) or paragraph numbers relative to section numbers instead. Say "Smith paragraph 12" or "Smith section 2" or "Smith Methodology paragraph 1" (where "Methodology" is the name of a section).
The following locations provide information on citing electronic sources:

The primary reason for citation is to credit the author and publisher with their original work; when using electronic resources it is also necessary to indicate "access points" for the information. The examples that follow are based on 4th edition MLA style. For more examples and in-depth explanations, consult the MLA Handbook, 4th edition, sections 4.8, 4.9, and 4.10.
Use the standard citation style for whatever type of source you are citing (e.g. A magazine article, a journal article, a newspaper article) then add the word Online followed by a period, then the name of the computer service, (italicized or underlined), and the date you accessed the service. Follow standard MLA style for presenting the date.

Citing Items Without Page Numbers--Excerpt from Li and Crane [Top]
For electronic journals, supply volume and issue, separated by a period, then date (in parentheses), followed by a colon and some indicator of the location of the article in the electronic journal or a notation on length.
Failing this, give "n.pag." for no pagination. This information is followed, in the case of commercial online databases and CD-ROMs, by medium statement, supplier, database name(italicized or underlined), database number, and item identifier.
