In other lessons, we cover how to upload new documents and update existing ones. Let's take a look at how we find older documents, and that is those that have been updated.

Here are some documents. By default, the list of documents shown are always the latest revisions. But what if we want to find a previous revision? Well, it's really easy. But first, we'll search for a specific document number so that we only have one document. And that will make it easier to understand what we're doing.

So here's the document. We can see the revision-- and remembering that this may be a letter or a number or a combination of both, depending on the convention that's being used by the project. There's a checkbox labeled Show document history. We'll check that and search again.

Now we see more than one document, but what we're actually looking at are the different revisions or versions of the same document. And this is essentially the history for the document. Each time the document has been updated, we see a separate revision or version. And sometimes, the revision changes and the status too.

We can open or download any of these revisions. And that's one of the benefits of Aconex. It keeps all the versions of a document in one place and it's really easy to see what's happened to a document over any given period of time.

Notice this document that's shown in bold, and that's the current version or revision. And this is the one we previously saw before we checked the Show document history box. It's shown in bold to make it easier to spot. As with any other set of search results, we can add additional columns, sort them, and export the results to an Excel report.
