NICHD Pediatric Terminology Publication Schedule
NICHD Pediatric Terminology is developed and revised on an ongoing basis. The most current version is published in NCI Thesaurus (NCIt) every month. The database is reconciled the last Monday of every month, and the files are posted during the following two weeks. The version name appears as YR.MOweek. An example is 11.02d which corresponds to the year 2011, the month of February, and the "d" refers to the fourth Monday of the month.
Each month a change file is published, which describes the changes that have been made to the terminology. The change file is available on the NCI EVS ftp site (http://evs.nci.nih.gov/ftp1/NICHD).
