We had a discussion in our ProGen class about how much to include of the URL of a website in a citation. There were a variety of opinions and so I went searching for an answer. The uniform resource locator or URL is the series of numbers and letters that forms the web address. It appears in your browser window and begins with http://. Sometimes it is very short but sometimes it is very long.
The options discussed were:
- Use a TinyURL. (If you are not familiar with TinyURLs check them out here.)
- Use only the homepage URL (e.g. http://ancestry.com) and
- Use the entire URL address.
Here is what I found.
Option #1: TinyURLs
Citation for this blog using a TinyURL:
Jill Morelli, “How Do You Handle URLs in Citations?” Genealogy Certification: A Personal Journey, 7 March 2014 (http://tinyurl.com/kmj9esc : accessed 7 March 2014).
TinyURLs take a long web address (URL) and turns it into a small one. For example, the Permalink for this posting is http://tinyurl.com/kmj9esc by using going to the TinyURL website and putting in the longer web address into the field and the site generated a unique but shorter address. The address for this blog is not particularly long but compare that address with this citation for an image at Ancestry.com:
Include the citation information around this link and you end up with six to eight lines for every footnote, sometimes consuming half of the page.
Why not use a TinyURL if you only wish to locate the source in the future–that works, doesn’t it? No, it doesn’t. What if the link is broken? What clues are you or the reader given to enable you to find the source again? The TinyUrL gives no clue as to which source you consulted to obtain the information. However, the long URL in the example above has embedded within it the site name of ancestry and information about the type of record and the name of the individual of interest.
Tom Jones, in his book, Mastering Genealogical Proof doesn’t even mention ease of retrieval as a reason to cite your sources. Instead, he describes citations as indicative of an exhaustive search and our use of “least error-prone sources” and to document our findings.  But if the citation uses a TinyURL, how can you determine if you have done a thorough search? You have no idea if the author cited Wikipedia or a peer reviewed journal article. You also are hampered in predicting the probability of error. The use of a TinyURL also does not assist in documenting findings.
I do not recommend using a TinyUrl in any citations you are writing.
Option #2: use of only the homepage URL
Citation for this blog using only the homepage URL:
Jill Morelli, “How Do You Handle URLs in Citations?” Genealogy Certification: A Personal Journey, 7 March 2014 ( accessed 7 March 2014), searched for citations & case study.
Elizabeth Shown Mills in her book, Evidence Explained, discusses web addresses (URLs) in section 2.37, page 59.  Her assertion is that long URLs are subject to change more easily thanthe shorter homepage address and may not link correctly at a later date. We all have encountered the ERROR 404 on a broken link. Broken links are not uncommon even in the most cared for site.
Ms. Mills proposes that we use the address of the home page but include any additional descriptors for finding the particular item cited. You can see in the example for this web site the search criteria of “citations & case study.” In a citation for a census image from http://ancestry.com, you might add “search for John Smith, Winchester County, Indiana.” If using the homepage appraoch, Ms. Mills offers no guarantees as websites can still be rearranged, but even if the homepage changes it might be possible to locate the document in the future through the use of Internet Archive Wayback Machine. The use of the Wayback Machine is an option not available if a TinyURL is used.
Option #3: Use the entire URL
Citation for this blog using the full URL:
Jill Morelli, “How Do You Handle URLs in Citations?” Genealogy Certification: A Personal Journey, 7 March 2014 ( accessed 7 March 2014).
In EE, Ms. Mills indicates the need to use the full address for journal articles and journals themselves. She continues by saying that most style manuals use the full URL  I found it difficult to tell if she was only talking about Journal citations or it was a more global statement. I analyzed each (yes, I really did!) of the QuickCheck Models in EE that pertained to online citations to try to discern a pattern of full URL vs. just the homepage URL.
- At no time did I find an example using a TinyURL.
- The full address was used more often, by a ratio of 2:1 (n=34,) than the homepage URL for citations that were related to online resources.
- In many, but not all, where the short address was used, the citation described the database and not a specific image. In my recent blog about “What is Context Anyway?,” citations have to be responsive to what is being cited. In some cases the “short form” was being used because…it would have been inappropriate to do anything else.
- but there were examples where Ancestry.com, for example, was cited using the homepage URL and the image was the focus.
I checked ESM’s EE web page (https://www.evidenceexplained.com/) and didn’t find any specific information on this topic, but you can read what I did find by going to this link: https://www.evidenceexplained.com/search/node/URL . And, if you find a relevant article somewhere, please share!
The Chicago Manual of Style provides, to me at least, the answer:
“URL or DOI.  Many of the examples in this section include a URL or a DOI at the end of the citation. A DOI, if it is available, is preferable to a URL. If using a URL, use the address that appears in your browser’s address bar when viewing the article unless a shorter, more stable form of the URL is offered along with the electronic article.” 
Three observations seem now apparent:
- Whatever is decided, be consistent across types of citations.
- The BCG certification “fear factor” makes each applicant ultraconservative in writing citations, resulting in full URLs more prevalent (observation based on my reading of several BCG portfolios.)
- I need to think about the context of the citation. If I am citing just the database or have a narrow site focus, use the homepage URL; otherwise…
- I will be using the long URL or DOI.
I would be interested in your thoughts, especially of those who are “on the clock” or already certified.
What I have done since the last posting: spoke to the Eastside Home Economists’ Club on “Soldier, Spies & Farmwives: the Changing Roles of Women in the Civil War.” It was well received; computer was down for 1.5 weeks. I suffered from major withdrawal; worked on my draft no. 2 of my Proof Argument for ProGen; tried to set up a time to meet with my business counselor but had to cancel; encouraged a friend to consider running for Vice President of SGS; worked on presentation of GPS Element #2 for SGS to be given on Sunday. I hope some folks come–its DST!

 DOI stands for Digital Object Identifier and is tied to the image, not to the website. The link is extremely stable.
