Welcome to the Grand Slam Project of the Tennis WikiProject. The project aims to create a page for every Grand Slam tournament and every grand slam tournament draw in history.
For the Grand Slam tournament draws there are several online sources of information (mainly Open Era):
ATPTour.com, the official site of the men's ATP Tour. It has HTML draws for all of the open-era men's slams which can be found at Scores > Results Archive (Example).
WTA Tour, the official site of the women's WTA Tour has women's draws as PDFs going back to 1968. These can be found at Tournaments > Tournament Archive (Example).
Australian Open (official site), which used to have a results archive containing HTML draws of all events going back to the inaugural edition of 1905.
Wimbledon Championships (official site), which has HTML and PDF draws of all events going back to the inaugural edition of 1877.
Roland Garros (official site), which has PDF draws for the singles events going back to 1925, the year the tournament opened to international competition.
The TennisForum website has virtually all women's singles and women's doubles draws dating back to the beginning of Grand Slam tournaments.
ITFtennis has full draws for many of the slams from the end of the Challenger era. For the men, they have the Australian, US, and Wimbledon back to the 1920s, and for the women they have Wimbledon and the Australian for the same time period. Search for something like "01/01/1900" to "31/12/1967" to see a full list. Note: since the launch of ITF's new website in March 2012 it appears that only draws from the open era are still available.
Other wikis, whose users have already created draw articles that just need to be translated to the English Wikipedia. A list of Grand Slam events for which there are articles on other language wikis but not the English Wikipedia can be generated with this query on Wikidata.
All sources need to comply with guidelines on reliable sources (WP:RS).
