Here are a few examples of how to cite different types of electronic sources, including electronic journals and books. Most examples come from the Purdue OWL or from the MLA Handbook for Writers of Research Papers.
Consult this section of OWL for more explanation of these examples and additional examples of how to cite electronic (web) sources of various types. Citing web sources can be problematic. The MLA Handbook (p. 182-183, for example) notes that many web sources do not supply all of the information normally desired for a citation. You may have to settle for providing whatever is available and improvising, keeping in mind the concept of providing enough information to help the reader evaluate and get to the source.
Basic Style for Citations of Electronic Sources (Including Library Online Databases)
OWL recommends trying to find the following data for electronic sources you will cite:
Abbreviations
It may be necessary to use abbreviations for information that cannot be found, such as:
This OWL page lists more abbreviations.
The basic format for citing an entire website is:
Editor, author, or compiler name (if available). Name of Site. Version number. Name of institution/organization affiliated with the site (sponsor or publisher), date of resource creation (if available). Medium of publication. Date of access.
