Iowa Departmental Rules (IDR)

The Iowa Departmental Rules (IDR) preceded the current Iowa Administrative Code (IAC). The IDRs were bound hard-cover volumes that contained the permanent rules of general application promulgated by the state departments. The IDRs were published in 1952, 1954, 1958, 1962, 1966, 1971 and 1973.

The IDR Supplements were bound paper volumes that contained the permanent rules of general application promulgated in the years between the IDRs. The IDR Supplements were published in January and July from 1956 through 1975. (Note: No IDR Supplements were published in January 1962, January 1966, January 1971 and January 1973.)
