What to Use—The Full Document URL or Home Page URL?
by Paige Jackson
Following on from Annie’s post yesterday on URLs, today I wanted to share some tips that might help in deciding what to use when. With the increasing predominance of electronic publishing, it’s a challenge to know how best to cite documents you find online. The DOI is the gold standard, and eventually all documents will have their own DOIs. In the meantime, it’s not always easy to know what to do. If you find a document on the Internet (but not from a database) that you want to cite for which there is no DOI, is it better to cite the full document URL or the publisher home page URL?
The question to ask before deciding which to include is, Which will be most helpful to the reader in locating the document? The following are some instances when the homepage URL would be most helpful (all examples refer to Chapter 7 in the Publication Manual):
- Subscription wall—If the document is available online only by subscription, the document URL would not be accessible by nonsubscribers. The homepage URL, however, lets the reader know who the publisher is and therefore what databases the reader might look to to access the document.
- Unstable document URL—If the publisher is one for which document URLs are subject to change, the home page URL is more likely to be helpful (see Examples 11 and 19a).
In the following cases, the full document URL is likely to take the reader to the source more reliably:
- Publisher website that’s difficult to search—Some publisher homepages—such as those of government agencies or nongovernmental organizations—can be difficult to search, so citing the full URL for a document that takes the reader directly to the document may save time (see Examples 9, 31, and 33).
- Message posted to a blog or other online forum—Similarly, it can be difficult to locate a particular message on a blog website, so providing the URL that will lead the reader to the message would be the best choice (see Examples 74–77).
This list is not exhaustive—we hope it will give a sense of factors that should guide your decision. A URL is imperfect in pointing the reader to an electronic source, but for many sources, it’s the best we can do. So don’t belabor the issue—make an informed guess as to whether the publisher home page URL or the full document URL is more likely to lead the reader to the document in question, and move on!
