Perma’s newest registrar, the National Constitution Center

We’re happy to announce the National Constitution Center has recently been brought on board as a Perma registrar. A private, nonprofit organization, the Constitution Center in Philadelphia, PA serves as one of America’s leading platforms for constitutional education and debate, fulfilling its Congressional charter “to disseminate information about the U.S. Constitution on a nonpartisan basis.”

The National Constitution Center will be using Perma to develop their online Interactive Constitution, which presents the full text of the U.S. Constitution along with essays by leading scholars from across a range of perspectives, and to prevent link rot in their explainers and white papers.


The NCC reached out to us to see if they could become a Perma registrar. Interested in seeing if your nonprofit or legal organization may qualify? Contact us!

Perma’s v0.76 release, cleaner and clearer

This week’s release pushed out improves to a smattering of areas. Worth noting:

  • UI: improvements to the navigation, as well as addressing a few bugs with the user login process.
  • Size limit consistency: we’ve now set a fixed limit in Perma.cc archive sizes, as well as files (images, PDFs) that are uploaded to replace the screenshot view: 100 MB.

Extensions and a Bookmarklet: Making Perma Links is Easier than Ever

Thanks to the hard work of our new Perma developer Rebecca Cremona, we’re happy to announce Perma.cc now has a snappy browser extension for easily creating Perma links, available in both Chrome and Firefox.

How does it work?

When you click the extension button in your browser (which appears as the Perma infinity symbol), a new window opens and directs you to the Create a Perma Link page, with the URL of the page you had been viewing automatically filled in.

Both extensions can be found at https://perma.cc/settings/tools, as well as in their respective browsers’ add-on/web stores:

The bookmarklet works similarly. the bookmarklet, which is also located in the Tools page, can be dragged into your browser’s bookmarks bar, and when you’re on a page you wish to Perma, simply click the bookmark and it will trigger the same process as above: opening a new Create Perma Link window with the URL auto-filled in.

We’re constantly working on more ways to make your Perma.cc experience faster and easier. Suggestions? Contact us!

Perma.cc: now a Memento-approved archive!

Memento is a project which aims to make web archives easier to access: rather than expect a user to know all the specific archive services available, Memento pulls together all archives that adhere to its protocol and allows other services to leverage this collection of archives. For example, Memento’s Time Travel Find allows users submit a URL and date, and, if there is an archive of it in one of the many archive services that Memento supports, it will direct the user to that archive.

We are proud to announce that Perma.cc is now a Memento approved archive! This means that a user searching for a webpage on Memento’s Time Travel Find project, or any other Memento tool that utilizes the protocol, will also have any applicable public Perma links served up along side the other Memento-protocol adhering archives.

Memento is also accessible as a Chrome extension.

A Tale of Two Shortlinks: Supreme Court Edition

Two recent instances of shortened URLs appearing in Supreme Court decisions serves as an excellent use-case of considerations for when linking to content on the web.

The first is the use of a shortened Google URL on page 5 of this decision:

googl-snip

This seems to be the first instance where a URL shortener was used in a Supreme Court decision (The shortened URL was copied from the Respondent’s merits brief). Using a Google URL shortener, in addition to saving space and appearing shorter, raises additional considerations:

  • Google makes the analytics public for its shortened links. Any organization that uses a shortened Google link must consider whether or not they want these analytics public regarding those who access content through this link.
  • While Google may not control the content that is linked to, it does control the redirect URL. This means that Google can choose to change – or take down – the shortened URL as it deems fit.

The second is the use of a Perma.cc link in page 5 of this opinion:

perma-snip

(Perma link originally copied from the Petitioner’s brief). The Perma link does shorten the URL used, but more importantly, the linked content is archived and preserved through Perma’s library partners, ensuring the accuracy of the link for those who who cite this opinion in the future and removing the risk of link rot.

Update: Dual citation is a smart choice when available, too, as it allows the reader to view the source directly in the text (instead of having to click the link), and makes the source URL reachable directly from the citation rather than just potentially through the archive’s URL. Hat tip to Herbert Van De Sompel for pointing this out!

Any courts interested in using Perma to preserve the accuracy and permanence of links in their decisions should reach out to the team at  info at perma.cc! We would be happy to assist you in creating an account; courts are eligible to create an unlimited amount of Perma links for their decisions.

Perma.cc – back at AALL!

Perma.cc will be back at the upcoming American Association of Law Libraries annual meeting in Chicago, spreading the good word of archiving and link preservation.

We will be sharing a table with our friends at LIPA on Saturday through Tuesday, July 16-19. Be sure to find us for some great Perma swag at table 819!

Perma v0.67’s release: Internet Archive-ing Perma’s public links

Perma v0.67 has been released!

Alongside bug fixes, we’re excited to announce that all public Perma links are now additionally being archived at the Internet Archive.

Following the “Lots Of Copies Keep Stuff Safe” principle – where an abundance of copies helps secure the content’s longterm presence –  public Perma links are being archived at the Internet Archive. Perma archives are thus having their preservation further ensured by another trusted, not-for-profit digital library.

What’s this mean in practice? Perma links are automatically archived with the Internet Archive, 24 hours after creation (within the first 24 hours a Perma link creator still has the ability to delete a newly created link).

Perma v0.66 – it’s here! it’s here!

This week the Perma team released v0.66 of Perma.cc. Here are a few of the notable updates:

  • You can now edit a Perma link’s title and notes when the viewing the Perma link itself – not just in the link management area:
    When viewing a Perma link you own, click “Show record details” and you will be able to edit these fields there.
  • Admin tools are more robust, including the admin-side registrar approval process.
  • pywb, one of the tools used in the archiving process, has been upgraded on Perma.cc.
