The Pennsylvania Senate and House of Representatives maintain official profiles of all members with various biographical data and contact information. Archived versions of former legislators may be obtained through the Internet Archive project. Either method might require some trial and error and a familiarity with the Internet Archive.
Method 1: - Select legislator's profile from these archived directories.
Each party's caucus in the House and Senate maintain official webpages for its members. Generally, each caucus' web development team follows a certain predictable pattern of assigning URLs for these webpages. Generally, the desired archived page can be found by replacing XXX with the legislator's last name. If that is unsuccessful, a certain amount of trial and error might be required. Try a variety of capitalization schemes or using the senator's full name in place of the XXX. If multiple legislators have the same last name, try various forms of the first initial. Alternatively, try using the Senator's name as the domain with .com, .net, or .org. The correct internet address might be referenced in an archived profile. Some of these strategies will yield official campaign websites, which are also valuable sources of material. Unfortunately, some Internet Archive queries are blocked by a Robots exclusion standard.

Project Vote Smart is a nonprofit organization that collects biographical and ideological data on candidates for office. It maintains some voting patterns on incumbents as well. To use the service, search http://www.votesmart.org/ for the legislator's profiles. Project Vote Smart pages data can be used for Inline citations or as External links. To use the {{CongLinks}} template, locate the individual's ID number, which can be found at the end of the URL string. For example, the profile for Bill DeWeese is at http://www.votesmart.org/bio.php?can_id=9119, making his id number "9119."
The pages are de-activated once a legislator is out of office, so consider using web archival services like WebCite (currently out of service) to preserve the data. Also consider using the "| quote=" parameters for inline citations.

This is a list of various newspapers in Pennsylvania that might be useful in finding relevant information. Please note that some newspapers (like the Pittsburgh Post-Gazette) maintain extensive searchible archives of old articles, while some newspapers (like the Philadelphia Inquirer) deactivate online articles quickly and charge for continued access. Please consult the {{Cite web}} template for information on how to use "archivedurl=" and "quote=" parameters to preserve volatile information. Most newspaper articles are not retrievable with the Internet Archive. Alternate sources of information include Google News Search at http://news.google.com/, which allows for date-restricted searches of some old newspapers articles. Many of these are scanned images of the original newspaper.
Some political news aggregators may serve as convenient starting points, as they may provide links to and summaries of appropriate news articles. Some, like PoliticsPA may contain feature stories and original content that might be appropriate for inclusion. Please consult Wikipedia:Reliable Sources before doing so. For example, Best and Worst Campaigns in 2002 or Top Political Activists might be appropriate for use. Use the Internet Archive to find older material on these sites. Per Wikipedia:Verifiability (at note 4), "blogs" maintained by journalists through a newspaper website may be considered "interactive columns" and may be acceptable for use in Wikipedia. Even though some material is offered to subscribers only, it is still permitted for use as a source. Be sure to use a full citation format and consider using the "quote=" parameter for facts that might be challenged.
