Aaron Swartz, a celebrated internet freedom activist and early developer of the website Reddit, has died at 26.

The activist and programmer took his life in his New York apartment, a relative and the state medical examiner said. His body was found on Friday.

A sad day, especially for those who share Aaron Swartz’s commitment to openness and admire his commitment to the development of tools, services and standards, such as RSS, which have helped to make open access to resources accessible on a global basis.

Earlier today I came across a tweet which encouraged academics to show their support for Aaron’s work:

Please share: Academics posting their papers online in tribute to Aaron Swartz using hashtag #pdftribute.

I would like to endorse this proposal. I have created a Storify summary of the #pdftribute tweets, which contains over 500 posts since the call was made just over 3 hours ago.

Although we have see that initial tweet being widely retweets, as @neuroconscience (Micah Allen) has suggested:

Folks as exciting as #pdftribute is we need less links talking about it and more actual paper posting.

But what could be said in 140 characters?

Within my Twitter stream I have already seen tweets from those involved in supporting their institutional repository including @SarahNicholas:

Cardiff academics! Post your articles to @CardiffOrca. #openaccess#pdftribute

and @glamlaflib (Sue House):

Glamorgan academics can deposit their articles & papers here (if you retained the copyright) http://dspace1.isd.glam.ac.uk/dspace/ #pdftribute

I have also seen @openscience endorsing @jambina’s reminder of the role which can be played by librarians:

Librarians: always friends in #openaccess, #openscience MT @jambina: librarians can help you free your work. we are on your side #pdftribute

Meanwhile @MrGunn describes services which can be used:

@opendna @venturejessica @Aine Mendeley can push into to local repository via Symplectics Elements, other routes can be made with Open API.

Of course many researchers are demonstrating their commitment to providing open access to their research papers:

whilst others provide a more political view:

@MarietjeD66 @mikebutcher Let this be the start of the end of the ridiculous copyright laws. #pdftribute #AaronSwarz

Would you like to join in by giving your views or ensuring that your Twitter community is aware of how you have made your research papers openly available?
