See "Legislative History" at the bottom of the page for more information.
Legislative materials of interest can be found on the webpage for Publications & Records of the Parliament. It contains links to Hansard, publications of the Houses, archives, and committee papers. One of the best sources for research is the Research Publications page; this page contains research papers produced by the Parliament libraries from 1996-present. This is a treasure trove of research as it gives extensive information.
The Hansard web pages provide comprehensive legislative history materials and should always be consulted for researching legislation. Hansard publishes debates from the House of Commons and the House of Lords. "Commons debates can be read back until November 1988 and Lords debates until 1995-96 on the Parliament website. Hansard debates from both the Commons and Lords from 1803-2005 can be read on the Historic Hansard website."
There are more ways to access legislation and parliamentary materials than listed. Some of the listed sources are the Bluebook preferred - consult Table 2. All sources listed are accessible in the library, via electronic subscription resources for students and faculty, or for free online.
