Because of the limited time that the legislature is in session, in-depth studies of important issues often are conducted by committees during interims. Generally, the lieutenant governor specifies interim charges for senate committees, and the speaker of the house specifies interim charges for house committees. Most interim studies result in a report to the senate or a report to the house containing the committee’s findings and recommendations. Copies of these reports can be obtained from the respective committee offices. Copies of senate interim committee reports also can be obtained from Senate Bill Distribution. The Legislative Reference Library and the Texas State Library and Archives Commission have extensive collections of interim study reports from the current and previous legislatures. Interim charges and interim reports are available online through the house of representatives' website and the senate's website. Current and historical interim charges and interim reports also are available online through the legislative reports page of the Legislative Reference Library’s website.
