<tr><td valign=top colspan=3>
    This informal volume of technical notes is of interest to 
    those who develop and maintain the HDF5 library and 
    related, closely-coupled drivers.
    These notes are not generally of interest to applications developers 
    and certainly not of interest to users.
    (Some of these documents may be somewhat out of date as they were 
    working papers for the design process.)
