How are bills identified?

There are four types of legislation: bills, joint resolutions, concurrent resolutions and simple resolutions. Any of these may be introduced in either chamber. Search Tools Overview is a guide for finding legislation in

Why are there different versions of bills?

Legislation may be changed or amended as it makes its way through the legislative process. You will sometimes see different bill text versions in the Text tab of a bill record. A table defining each of the possible bill text versions can be found on the GPO website: Definitions of Common Versions of Bills.

The full text of a bill I need is not on yet. What can I do?

Check to see if the bill is available on GPO’s govinfo. Since GPO is the source of bills for, a bill may appear sooner on GPO. In the current Congress, a bill or resolution normally will appear under the bill profile Text tab a day or two after it has been introduced on the floor of the House or Senate. Delays can occur when there is a large number of bills to prepare or when a very large bill has to be printed quickly. The system checks for new electronic
copies sent from GPO throughout the day and begins the update process as soon as a bill or resolution is received.

Please note that when both the House and Senate pass or adopt legislation containing the same legislative text, an ENR measure is created and made available online. The paper version (the official document of record) is presented to the President for his signature. The time between when the last chamber agreed to the legislation and the ENR version is made available at GPO’s govinfo is variable and largely depends on the size of the legislation. Larger documents take longer to prepare. The time between when the ENR is available and additional action steps by the President are made available is also variable and depends on the actions taken by the President. More information on Presidential actions and some of the timeframes can be found in “How Our Laws are Made”.

What is the difference between policy area terms and legislative subject terms?

Legislative analysts from the Congressional Research Service (CRS) closely examine the content of each bill and resolution to assign Policy Area Terms and Legislative Subject Terms. Each measure is assigned only one of 32 possible Policy Area terms. There is no limit to the number of legislative subject terms that may be assigned. Assignment of a Policy Area term is made when a new measure is added to, while it may take longer to add legislative subject terms. If a measure is revised as it moves through the legislative process, additional subject terms may be assigned. Amendments are not assigned policy area or subject terms.

The Legislative Indexing Vocabulary (LIV) is an older CRS thesaurus that was discontinued in 2008. For more information on using terms from all three subject vocabularies to enhance research, see Find Bills by Subject and Policy Area.

Why has the short title not yet been added to a bill?

Short titles are manually added to bill records after the bill text has been published and is available on govinfo. The bill’s official title will display until the bill text is available and the short title can be verified. The glossary provides more information about short titles.

Where do I find Conference Reports?

Conference reports published since 1995 are available from

Conference reports are published in the Congressional Record and also in the congressional report document series. They may be available on House committee websites, especially the House Committee on Rules site or on the House Text of Bills to be Considered on the House Floor site before they are published in the Congressional Record.

Why doesn’t the bill number in my On the House Floor Today or On the Senate Floor Today email link to the bill? is updated early each morning with bills introduced on the previous day. So if a bill is considered on the floor on the same day it is introduced, it will be listed in your On the Floor email that day but will not be available on until the next day. You can find the bill when it is available by searching on the bill number.
