These are currently filed between S and T in the Thode Library Reference section (Lower Level). They are in big green binders (note: a number of standards are missing).
These have designations such as:
<CAN/CGSB-38.107-93>, <39-GP-11M> or <62-GP-2b>
These standards are filed in numerical order in the binders. There is a paper index in Quick reference; however it is out-of -date but good for general information about the standards. (CA1 ST35 C31). More information can be found on their website .
