Arquivo404 presents web-archived pages instead of “pages not found”

Does your website presents “Error 404 – Page not found” messages to your users?

Arquivo.pt offers a solution for this problem through Arquivo404.

Just insert a single line of code in the page that generates the 404 error message on your website and web-archived pages will be presented to your users instead of pages not found.

See these examples on websites that installed arquivo404.

How does Arquivo404 work?

example-fccn-arquivo404_

When a page is no longer on a website, Arquivo404 checks if a preserved version exists.

When a user tries to access a page that is no longer available on a website, Arquivo404 automatically checks if there is a version of that page preserved in Arquivo.pt.

If the page exists in Arquivo.pt, a link is presented so that the user may visit this version. If it does not exist, the normal error page is displayed.

See Arquivo404 at work in this example of an error page that presents a link automatically generated by Arquivo404.

How to install arquivo404 on your website?

The simplest implementation of arquivo404 is to insert the following Javascript on the HTML code that generates the “Page not found” message:

<script type="text/javascript" src="https://arquivo.pt/arquivo404.js" async defer onload="ARQUIVO_NOT_FOUND_404.call();"></script>

The code in Arquivo404 can easily be adapted. You can for example create a customised error message.

Hint for WordPress websites: When editing the 404 error page and inserting the arquivo404 script inside the <body>, you must put the <!– wp:html –> tag at the beginning and the <!– /wp:html –> tag at the end, otherwise the script will be deleted.

Last updated on August 23rd, 2022 at 11:51 am

Arquivo.pt launched a new version, called Francisco, on the 19th of January 2022.

The SavePageNow function stands out, allowing anyone to save a Web page to be preserved by Arquivo.pt.  It is only necessary to enter a page’s address and browse through its contents.

Arquivo.pt SavePageNow was inspired on the Internet Archive Save Page Now and implemented using webrecorder pywb.

For example, a publication on the FCCN blog marking the 30th anniversary of the Internet in Portugal was saved with SavePageNow and preserved at Arquivo.pt. This way, anyone using SavePageNow is contributing to the contents published on the Internet not being lost.

Create automatic narratives about any topic!

thumbnail-narrative-q2

Arquivo.pt provides a new function that allows you to automatically create temporal narratives on any topic.

The “Narrative” functionality, integrated into Arquivo.pt in September 2021, is the result of the collaboration between “Conta-me Histórias”, winner of the Arquivo.pt Award 2018, and Arquivo.pt.

The Conta-me Histórias” (Tell me Stories) project was developed by researchers from the Laboratory of Artificial Intelligence and Decision Support (LIAAD – INESCTEC )  and affiliated to the institutions Instituto Politécnico de Tomar – Center for Research in Smart Cities (CI2) ; University of Porto and University of Innsbruck .

How it works?

When a user enters a set of words about a topic in the Arquivo.pt search box and clicks on the “Narrative” button, the user is directed to the “Conta-me Histórias” service, which automatically analyzes the news from 25 websites archived by Arquivo.pt over time and presents a chronology of news related to the topic.

For example, if we search for “Just Bieber” and click on the “Narrative” button (Figure 1), we will be directed to the “Conta-me Histórias” , where we will automatically obtain a narrative of archived news (Figure 2).

Create your narrative now!

“Conta-me Histórias” researches, analyzes and aggregates thousands of results to generate each narrative about a topic. It is recommended to choose descriptive words about well-defined themes, personalities or events to obtain good narratives.

Creating a narrative is useful for researchers, journalists or citizens who want to quickly get an overview of the evolution of a topic along time, thus saving them a lot of time and effort.

Go to Arquivo.pt and try to create a narrative about a theme of your choice.

Exported results into an Excel sheet of a search for the word "universidade", university, limited to 10 items

Arquivo.pt launched a new version of its service on July 1, 2020 named Responsive.

The purpose of this version was to improve the user experience between different devices and add new features.

Replay a past webpage using a browser from the past

We added an option to view the archived page using a browser from the past. In the Options choose Replay with old browser and you will be redirected to the oldweb.today service that emulates browsers such as Netscape NavigatorMicrosoft Internet Explorer or NSCA Mosaic.

This external service is useful for research use cases, in areas such as Web design, Art, Communication or History,where it is necessary to access the original visual aspect of a page from the past in the most reliable way possible.

Try this new option from Arquivo.pt to replay the European Map of WWW/NIR sites in 1996 using a contemporary browser or any other historical page using the Oldweb.Today service.

You may have to wait a while for your request to be processed but it is always faster than having to install a browser from the past on your computer.

Export search results to spreadsheet format

This new function enables users to save their search results for further treatment and analysis. This is specially useful to perform thorough research about a given topic.

After a search, in the Options, just choose one of the available formats to export the obtained results: XLSX, CSV or TXT.
