Borrow Direct
Borrow Direct is an interlibrary loan service that allows member university students, faculty, and staff with library borrowing privileges and active e-mail accounts to borrow books directly from the libraries of the other member universities. The patrons' home library bears the cost of the service and there is no charge to patrons. The service began within and slowly spread to all the members of the Ivy League, and has expanded since 2011 with the inclusion of the Massachusetts Institute of Technology to non-Ivy institutions.
Only print monographs are eligible for Borrow Direct; patrons may not request journals, microfilm, electronic resources, compact discs, digital video discs, or other non-print media. The Borrow Direct system will not allow patrons to place requests for items that the library believes to be available for checkout locally. Items requested are normally delivered within four business days after the request is placed, with an initial loan period of six weeks, with one renewal. Items may be recalled by the owning library at any time.
History
Borrow Direct went live in the fall of 1999 after a four-year planning and development period during which the three founding institutions, Columbia, Penn, and Yale, partnered with the Research Libraries Group for project management and assessment. The Borrow Direct Partnership expanded to seven member libraries in 2002 with the addition of Brown, Cornell, Dartmouth, and Princeton. In 2004, the Partnership exceeded 100,000 transactions for the first time. The Partnership grew to include Harvard and MIT in 2011. The University of Chicago, Johns Hopkins University, Duke University, and Stanford University joined the Borrow Direct Partnership in 2013, 2014, 2015, and 2017, respectively. Since its inception, Borrow Direct has successfully filled over 1.8 million user requests and counting.Participating Institutions
