| A basic solution takes advantage of the fact that Wikipedia stores and makes available every previous version of every page that currently exists. In what follows below, I'll show you how you can find and cite a more durable URL (Uniform Resource Locator, or web address) that will only ever point to a specific version of a specific page. For many contexts, this is a sufficient solution, but please note that it is not comprehensive and far from "future proof" or permanent in an archival sense. Wikipedia pages can be deleted and once a page is deleted it becomes [https://en.wikipedia.org/wiki/Wikipedia:Viewing_and_restoring_deleted_pages much harder] to find their content again. Overcoming that requires a more advanced solution. | | A basic solution takes advantage of the fact that Wikipedia stores and makes available every previous version of every page that currently exists.

| Let's say I want to cite the article on the [https://en.wikipedia.org/wiki/Seneca_Falls_Convention Seneca Falls Convention]. Here's a screenshot of that article taken in February, 2020.

| If you click on that screenshot or navigate to any Wikipedia page (or just look at this page—even though it's not on Wikipedia it uses the same software and a very similar interface), you'll notice a little blue link near the top-right corner of the article text that says "View history." Click on that link!

| === 2. Select the version of the page you want by timestamp === | |
| | |
| Now you should be looking at something called a "revision history" for the original page. There's a bunch of stuff, but the main thing we're interested in is the list of things going down the middle of the page. Each of the items in this list is a previous revision of the article you were looking at a moment ago. Each row corresponds to one revision and includes some useful information such as the timestamp for when the edit was saved, the username of the editor who saved it (if applicable), the length of the article in bytes after the revision (and the length of the revision in parentheses), as well as any edit summary text that the editor entered at the time they saved the revision.

| [[File:Seneca_falls_convention_viewhistory-20200212.png|thumb|center|2. What you see after you click "View history". Notice that the previous revisions are organized in reverse-chronological order. Also notice that each revision has a timestamp associated with it (a column near the left) and that you can click on any of the timestamps to view the revision in question.]]
| |
| | |
| Assuming the page looked okay to you when you clicked "View history" a moment ago, the version you want is the most recent one right at the top of the list (the revisions are organized in reverse chronological order by default). Go ahead and click the timestamp for this revision.

|
| |
| At this point, you should be looking at the article again. Indeed, if you clicked the most recent revision from the list, you are looking at ''exactly the same version'' of the article you had seen before. So what's changed? Well, for starters, the address (URL) of the page. Look at the end of it closely. It should end in "&oldid=XXXXXXXX" where the X's correspond to some numbers. This means that the address points to the specific version of the article you clicked on from the revision list. The number is called a "revision ID" and each revision ID is, in theory, unique (database errors happen, but let's just assume that's not the case because it would be a bigger issue if they started duplicating such IDs on Wikipedia...). The other difference is the little yellow box of text across the top of the page that basically explains that the address is a permanent link.

Notice that the URL (address) for the page contains the text "&oldid=XXXXXXXX" where the X's correspond to some numbers. Also notice that the yellow textbox across the top of the page indicates (not quite accurately?) that the address (URL) "provides a permanent link to this version."]]

|
| |
| Now, finally, you have a link you can trust to point to the version of the page that is exactly as you saw it when you visited.

|
| |
| === 4. Incorporate the "oldid" URL into your preferred citation format ===
| |
|
| |
| Once you have the oldid URL, you can go ahead and cite this URL using your preferred citation method. If your instructor, students, audience, or readers wonder why, just send them to read this page.

| == Are there more advanced solutions? ==
| |
|
| |
| I called this a "basic solution", so are there others? You bet. These get more involved because they entail using another site or tool to create an archival copy of the version of the page corresponding to the revision you want to cite. One example of such a tool is [https://perma.cc perma.cc], which is what my collaborators and I use when we're citing URLs in our published work. Perma.cc is a subscription-based service that we get access to through our universities, so if that's not an option, you might also use something like the [https://web.archive.org/ Internet Archive's Wayback Machine], where there's a little text-field where you can enter a URL to "Save page now." The Internet Archive also has browser extensions linked from their homepage if you prefer that kind of thing (I can't vouch because haven't used them myself). For most people most of the time, I suspect that these even-more-permanent archival links are not necessary. That said, at least you know about them now in case they ever become something you're looking to use!

| == Wait, does this mean I can cite Wikipedia for ''anything'' now? ==
| |
|
| |
| Well, hold on there, cowboy. Wikipedia is, like any other information source, only as good as the evidence behind it. In that regard, nothing about my recommendations here make any of the information on Wikipedia any more reliable than it was before. You have to use other skills and resources to assess the quality of the information you're citing on Wikipedia (e.g., the content/quality of the references used to support the claims made in any given article). Like I said above, the problem this really tries to solve is more about how to best cite something on Wikipedia, given that you have some good reason to want to cite it in the first place.
