consulted more accurately than the URL or other identifier alone. You may also copy anonline source you intend to cite onto your hard drive or a CD, so you will have a stable copythat you or your readers can later consult. Chapters 17 and 19 provide many examples ofaccess dates in citations.SUBSCRIPTION-BASED AND RESTRICTED SITES. Many online databases, journals, and otherperiodicals are accessible by subscription only. Similarly, some Web sites and Weblogs arerestricted to users who have registered or otherwise applied for access. When citing suchsources, you do not need to identify them as “subscription-based” or “restricted”; simplyinclude the URL and access date, as for any other online source.15.4.2 Other Electronic MediaSources available in other electronic media, such as CD-ROMs, are more stable than thoseposted online. Those that are reproduced and distributed in quantity should be cited similarlyto published books, with the addition of information about the medium; see 17.5.8 (forbibliography style) or 19.5.8 (for reference list style).If a source is available in more than one electronic medium (for example, online and onCD-ROM), or both electronically and in print form, consult the most stable version, andalways cite the version you consulted.15.5 Preparation of CitationsYou can ease the process of preparing and checking citations if you anticipate what you willneed.Use the most reliable sources, in their most reliable version. If you find second- orthirdhand information, track down the original source.If a source is available in multiple versions, always cite the one you actually consulted.There may be small but important differences between the versions that could affect theaccuracy of your quotations or other references to the source.Record all bibliographical information before you take notes. See figure 16.1 (forbibliography style) or figure 18.1 (for reference list style) for templates showing whatinformation is needed for several common types of sources.Record page numbers for every quotation and paraphrase.As you draft, clearly indicate every place where you may need to cite a source. It is mucheasier to remove an unnecessary citation when you revise than to remember where youmay have relied on someone else's ideas.When your draft is in its final form, consult chapter 17 or chapter 19 to ensure that eachcitation is in the correct form, including punctuation and spacing.
