# HDF5 Technical Notes

### Technical Notes for HDF5 Library and Driver Developers

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 (Some of these documents may be somewhat out of date as they were working papers for the design process.)
