The following information was taken from the Oughtred Society's brochure:

"The Oughtred Society was formed in 1991 to serve the needs of the growing number of slide rule collectors and historians.  Their objective is to promote an understanding and appreciation of the slide rule as a calculating instrument and to explore its history.  The Society takes its name from William Oughtred (1574-1660), the inventor of the slide rule.  From a nucleus of 11 charter members the Society has grown to become a worldwide organization with over 400 members.  It has established a journal, a biannual swapsheet and a series of popular annual meetings of collectors."

"The Oughtred Society invites you to become a member and explore the history of the slide rules and their makers, learn more about the many types of slide rules and their uses, and buy, sell or trade with other members to enhance your collection."

"As a member of The Oughtred Society you will receive:

• Two issues of the Oughtred Society Journal (Spring and Fall)
• Free listings in the biannual swapsheet
• Two issues of the swapsheet (Winter and Summer)
• The current directory of Oughtred Society members
• An invitation to the Society's annual meeting
• Notice of other meetings of slide rule collectors, both in the U. S. and abroad"
