[CODE4LIB] Durability of PDFs

2009-06-15 Thread Mike Taylor
Dear CODE4LIB colleagues, In one of my alternative incarnations, I am a zoological taxonomist. One of the big issues for taxonomy right now is whether to accept as nomenclaturally valid papers that are published only in electronic form, i.e. not printed on paper by a publisher. In a discussion

There are items/options that can be used within a given PDF that will drastically affect how likely it is that the PDF will still be readable. * Inclusion of 3D applets or any Adobe Acrobat specific features I have seen PDFs with 3D chemical applets embedded somehow into the PDF using a

It is worth following up on Xiaoming's statement of a limit of 100 uses per day of the xISSN service with the information that exceptions to this limite are certainly granted. Annette probably knows that just such an exception was granted to her LibX project, and LibX remains the single largest
