(Cal TF) paper on Technical Reference Manuals Best Practices from Across the Nation to Inform the Creation of the
California Electronic Technical Reference Manual (eTRM), some findings revealed that most successful jurisdictions
across United States follow similar key practices in developing the TRM.
