Citations in scholarly literature, in bibliographies, and in some indexing sources to Parliamentary, or Sessional, papers have these elements: Document title, session year, paper number (if given), volume number (a roman numeral) within the session year, and volume page number. For example: Estimate for Completing Exhibition Building 1863 (382) XXIX 381.
Using the online indexing features of the web sites in the Parliamentary, or Sessional, Papers--Full texts section of this guide is usually easy enough. Using the Sessional indexes for the micro sets is difficult. But here are some paper indexes, just in case the online indexing is insufficient.

British Government Publications, an Index to Chairmen of Committees and Commissions of Inquiry, 1800-1978. Z 2009 .R535 1982 v. 1-3
The purpose of this volume is to help researchers ascertain the volume in the Sessional Papers in which any particular Command Paper whose number is known may be found between 1833 and 1961/1962. The only information provided after the command number and session year is the volume number and pages where the document is located in the Sessional Papers. Use this if you have reference to a Command Paper by number but lack information on the session year, volume number, and page. Then take this information and go to the Hollander MakeCentral on 2nd floor west of the Main Library and use Microprint #10, the Sessional Papers on microcards. This book has been digitized and is available in HathiTrust, here.
