Disrupting access to scholarly journals

What happens when scholars bypass the library? In new and probably illegal ways?

Why would you want to pay 30 USD for a 20 year scientific article?

It’s nothing new. Scholars have always exchanged information. In olden days, before the deluge of videos shaming cats for silly behaviour, scientist regularly needed access to papers that were not available through their university library. When that happened, they asked their secretary to write the author of the paper, and request a copy.

It was institutionalized. When you submitted a paper to a journal, you were expected to buy a number of preprints of the paper from the journal. That  covered some of the cost of printing the journal, and you were welcome to distribute the preprints among your colleagues. You were annoyed that you had to buy them, but you actually needed them, to promote your own work, so that was OK.

Then the internet happened. Scholarly journals became digital, information suddenly had the potential to become very free. Scholars had instant access to huge numbers of scientific papers. Information could travel around the globe almost instantly. What also happened, was that the cost of subscribing to the journals went through the roof. No university library today can afford to subscribe to all the journals that researchers want access to. The publishers still want to be paid for the access, so they erect paywalls around their content. If your university library does not subscribe to the journal you want to read, you can pay to get access.

Okay. The scene is set. We have scholars, who believes that information should be free. We have information with a very high potential for being set free. And most of that information is hidden behind paywalls, where some scholars have access, and others dont.

Solution? Write to a colleague that has access, and ask him to email you a pdf.

Again, nothing new. We’ve seen it before. If we could gain access to the emails, we could describe the networks exchanging pdfs.

It might even be possible to describe this situation with nice formulas. It is probably analogous to the potential energy harnessed by cells, then there is a difference in the concentration of sodium ions across a cell membrane.

But now something interesting has happend (it actually happened a couple of years ago).

Researchers have begun using Twitter to request copies of papers they otherwise wouldnt have access to. They tweet the hash-tag “#ICanHazPDF, along with a reference and an email-adress. And kind people around the world, with access to the paper, send a pdf-copy of it. Quick. Easy. Free.

That was a very long introduction, inspired by this post. Whats next? In the next couple of posts, I’ll try to analyze what the consequences of this new-ish phenomenon might be. Maybe we’ll even get some numbers.

 

Rotoscoping

I ved godt hvad det er – I så det i A-HAs hit “take on me”.

Her er en katte-gif. I gamle dage var GIF bare et grafikformat. De kunne godt nok animeres, men det var lidt tungt, filer fyldte for meget og sådan. Og så blev de primært brugt til at lave hjemmesider der ikke var til at holde ud at se på.

I dag er de på mode igen – så meget at folk ikke tror at GIF også bare er et billedformat, men at de fuldstændigt er associeret med animerede gifs.

Men det var ikke det der var den egentlige pointe. Pointen var at lave en rotoscopet animeret gif.

Man starter med at finde en gif. Her er en god en, der fint illustrerer hvordan jeg har oplevet de sidste ca. 24 timer (nu er der kun fem kvarter til det er weekend. Yay!)

Og her er så resultatet af en rotoscoping:

t00zm

Nå. Hvad gjorde jeg så?

  1. Jeg startede med at lede efter et billede der udtrykte min sindstilstand. Egentlig var det et hamsterhjul med en hamster jeg ledte efter. Men det passede sgu meget godt at katten havde fået skåret halen af (stakkels kat). Giffen blev downloaded.
  2. I IrfanView (enestående fantastisk program!!!) splittede jeg filen af i dens enkeltbilleder.
  3. Hvert enkelt billede fik følgende behandling:
    1. CTRL-E – vælg edgedetection. Det finder “kanterne” på billederne, der hvor der er overgange mellem forskellige farver.
    2. ALT-I (for image), vælg negative – alle kanaler.
    3. Gem.
    4. Egentlig burde hvert enkelt billede også konverteres til gråtoner, det ville få det endelige resultat til at fylde mindre. Det var jeg for doven til.
  4. Herefter skulle billederne samles til en animeret gif igen. Det skete på ImgFlip. Der er andre værktøjer. Jeg har bare ikke fået downloadet GIMP endnu, efter min forlovede har opgraderet computeren til windows something (10?). Så jeg hoppede på nettet og fandt noget.
  5. Vupti! Der er et vandmærke der irriterer og sådan. Og næste gang laver jeg øvelsen under punkt 3 i ImageMagick i stedet. Den kan nemlig automatiseres. Det kræver en særligt desillusioneret hjerne at sidde og gøre det i hånden for par-og-firs billeder.

Hep! Sådan.

Rotoscoping

It’s been a little quiet around here. A lot of things have happened, maybe to many given the activity here.

We are getting ready to open the DataLab. The InnovationLab have had its first workshops (and I have to build a gadget to fix a problem with one of the printers – it is going to be ugly. But it will work!)

But right now I’m waiting for someone to send me an image. Before I get that, I cant send out our annual user satisfaction survey. So – an unexpected break!

Therefore a post that would normally show up at another blog, dedicated to geeking out. But relevant here.

One of the latest trends in library marketing is the promotional video. At our library, we appear to be fond of LEGO stop-motion animations. But “my” library is a small one, and we are frequently left out of the videos. For good reasons, but still, something must be done!

It is time consuming to produce a stop-motion video. And its been done. Instead we should do something that has’nt been done before. But it should be cool. Enter the music video for AHAs hit Take On Me. It used a technique called rotoscoping, to mix ordinary imagery with sequences that appear to have been drawn in hand.

How to do that?

  1. Download ImageMagick
  2. Make an ordinary video
  3. Download IrfanView
  4. Split the video into individual frames, using IrfanView
  5. Process the frames with ImageMagick – edgedetect and negate are the filters we’re going to use her
  6. Splice all the frames together again to a video

Simple. Allthough it does require a lot of time. But first of all – sell the idea, and make a storyboard.
