Arquivo404 with new methods for defining time intervals

Arquivo404 is a service that presents website users with links to web-archived versions, instead of laconic “Page not found” error messages.

However, sometimes it is necessary to specify the correct version of a web-archived page to be displayed. For example, a website’s domain may have belonged to another entity in the past, and only web-archived versions since the website came under its current owners should to be displayed.

setMinimumDate( minDate : Date ) – specifies the earliest date of the web-archived version of the URL that can be displayed.

setMaximumDate( maxDate : Date ) – specifies the latest date of the web-archived version of the URL that can be displayed.

setMostRelevantMemento( criterion : ‘oldest’ | ‘most-recent’ ) – specifies the order of results for the versions retrieved from the web archive. By default, the oldest version is displayed ( ‘oldest’ ).

In short, Arquivo404 now allows you to define whether to display the oldest or most recent web-archived page to the users, within a certain time interval.

CitationSaver processes HTML documents

CitationSaver is a service that extracts citations in documents to online resources and archives them. This service is particularly useful for maintaining the integrity of scientific articles and the reproducibility of the experiments and studies described in them.

Many open-access articles are published in hypertext format (HMTL). CitationSaver now processes documents in HTML format, in addition to PDF and TXT formats.

For example, if a user finds an article on the Web which contains citations to online resources, he/she simply needs to submit the URL of the article into CitationSaver. The URLs cited in the article will be extracted and their content will be web-archived for later access.

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?

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.
