Congress introduces legislation in four different forms: bills, joint resolutions, concurrent resolutions, and simple resolutions. The bills, designated as "H.R." or "S.", and the joint resolutions, known as "H.J. Res." or "S.J. Res.", may be enacted into statutes.
Bills and resolutions are found on microfiche filed in cabinets in the Microform Room. The microfiche are assigned the Library of Congress classification number Z1223 .A3. Within this classification number the fiche are organized numerically by the Superintendent of Documents classification number. Senate bills are filed under the number Y 1.4/1:, and House bills are filed under the number Y 1.4/6:. Senate joint resolutions are filed under Y1.4/3:; House joint resolutions, under Y 1.4/8:.
Bills and resolutions are numbered consecutively at the time they are introduced into Congress. Because bill numbers repeat themselves each Congress, the year or Congressional session is critical to finding the bill. To find all versions of a bill or joint resolution and track its progress, printed and online resources are readily available.
