the DOI issue is as described by "aroch" Quickscrape is capable of downloading PDFs, given a DOI I think: https://github.com/ContentMine/quickscrape If publishers listened to their readers we would have had 100% Open Access ten years ago. Traditional academic publishers do not listen and don't care. Even if I could convince say PLOS to do something about this it wouldn't change much. We need all or the majority of pu…

Well hopefully the coverage of full-text link metadata in Crossref will increase over time. Until then, best of luck to ContentMine! Improving metadata coverage is a different issue than changing business model. Objectively, one's easier to implement than the other. It is indeed tricky getting ~5,000 publishers to provide optimal metadata, but it's a good thing to have an industry-standard platform to do it in. (I wo…

Do you mean having all DOIs for all referenced papers included in the pdf metadata somehow? From my experience, authors don't know LaTeX well enough to do that. Half of them don't even read the submission guidelines that clearly say not to put page numbers on the camera-ready paper; they're never going to understand complicated metadata commands...

The metadata in papers is the responsibility of publishers not authors.

Thanks for the stack trace. Yes please, sample PDFs with problems would be great! You can find my email in my profile.

Maybe I just show you next time we run into each other at the 'lab or so ..

Use a reader like evince and toggle the checkbox.

Nice! Thanks for that! If you only knew how much I've looked for something like this, and, not to brag or anything, my internet-search-skills are prettttttty sharp. For others information (from wikipedia): "Evince used to obey the DRM restrictions of PDF files, which may prevent copying, printing, or converting some PDF files, however this has been made optional, and turned off by default[...]"

You're welcome, have fun! I only found out about it by luck myself.

I've installed pdfx and saw the help info as the demo. But when I tried to download the example 17 pdf files the following error msg jumped in the end ERROR 2: len() takes exactly one argument (2 given) What does this mean??

Thanks, you found a bug! I've fixed it right now. You can update pdfx with

    $ easy_install -U pdfx
