Details to Note

A website citation consists of the author (if any) webpage title, edition, place of publication, publisher, date of publication, date of last update, date accessed, and a URL. A database citation consists of the database title, edition, place of publication, publisher, dates of operation, date of last update, date accessed, and URL. The CSE notes that most websites, especially homepages, do not list individual authors. If there is any doubt about attribution, use the "Website with No Author" format listed below.

Some of these citation elements are not readily available from all websites and databases. If you are unable to locate one of these items, omit that element from your citation.

Use the formats described on this page to cite a website or database only. For other electronic sources, consult the corresponding pages of this guide, which are linked on the left (eg: the citation format for an eBook is described on the "Books & Book Chapters" page). Some online sources such as videos and blog posts are included on the "Miscellaneous" page as well.

The order of elements in your citation will vary according to the in-text citation style you are using. Examples are listed on this page for both scenarios. For more information about in-text citations, refer the the CSE Style Guide homepage.
