But in 1905 Jane Stanford directed that after her death, her jewels should be sold and the funds used as a permanent endowment "to be used exclusively for the purchase of books and other publications."[3] The board of trustees confirmed this arrangement, and the Jewel Fund was established in 1908.[2] It has been augmenting the university's library collections for more than 100 years.[4] The endowment, originally $500,000, is now worth about $20 million.[4] Items purchased through the Jewel Fund display a distinctive bookplate which shows a romanticized Jane Stanford offering her jewels to Athena, the goddess of wisdom.[5] Since 2007, benefactors who provide endowments for library acquisitions are referred to as members of the Jewel Society.[6]
