    27. 27. herbert van de sompel It is -- at least -- legitimate to reflect on the possibility of a digital system for scholarly communication that is not merely a scanned copy of the paper system. In order to free our minds: let’s forget about who has been doing what and how in the existing system.
    28. 28. herbert van de sompel A preprint in a digital scholarly communication system registration yes certification no awareness yes archiving no rewarding no accessibility high availibility
    29. 29. herbert van de sompel A preprint in a digital scholarly communication system registration yes certification no awareness yes archiving no rewarding no accessibility high availibility
    30. 30. herbert van de sompel Registration via preprints suggests the feasibility of a decomposed system for scholarly communication.

    32. 32. herbert van de sompel Communication via preprints suggests the possibility of preprints being the starting point of a new value chain in which the raw material -- the non-certified preprint -- is in open access.

    35. 35. herbert van de sompel <ul><li>This urges us to think about: </li></ul><ul><li>how the functions of a scholarly communication system can be implemented in a digital environment </li></ul><ul><li>how the functions of a scholarly communication system can interoperate disregarding their implementation </li></ul>

    44. 44. herbert van de sompel So what about the library? [ back to the who does what question ]
    45. 45. herbert van de sompel Within the existing system, Libraries are trying hard to optimize the output of a system with far from optimal input.
    46. 46. herbert van de sompel It has become increasingly difficult for Libraries to fullfill their fundamental role of safeguarding equity of access.
    47. 47. herbert van de sompel In the PDF version of the information chain, Libraries are aggregating the aggregators. That is a lot of aggregating for a digital world.
    48. 48. herbert van de sompel At the core of the problems that Libraries are facing is the total dependancy on information held upstream in the information chain.
    49. 49. herbert van de sompel <ul><li>As such, there are numerous incentives for Libraries: </li></ul><ul><li>to rethink themselves </li></ul><ul><li>to be pro-active in exploring alternative mechanisms for scholarly communication </li></ul>
    50. 50. herbert van de sompel <ul><li>Libraries are close to authors : </li></ul><ul><ul><li>a great position to fullfill the registration function i.e. obtain institutional material </li></ul></ul><ul><ul><li>a great position to archive institutional material </li></ul></ul><ul><li>Libraries are fast at embracing new tech nologies </li></ul><ul><li>Libraries have very knowledgeable people </li></ul><ul><li>Libraries provide a level of redundancy in services that is no longer required in a digital environment </li></ul><ul><li>The L ibrary as an institution that safeguardes equity of access has g lobal representation </li></ul>Libraries: the good news
    51. 51. herbert van de sompel <ul><li>As organizations Libraries are slow movers, hosted by slowly moving institutions </li></ul><ul><li>Libraries are slow to recognize the fact that a new technology may allow [or beg] for a new mode of operation </li></ul><ul><li>The -- information -- world runs on Internet time </li></ul>Libraries: the bad news
