By this date, Virginia Tech Interlibrary Loan had processed more than 207,000 borrowing, lending, and document delivery requests through ILLiad.
July 2002
ILLiad was being used at more than 250 institutions, including one-third of the major research libraries in the United States. By this date, Virginia Tech Interlibrary Loan had processed nearly 400,000 borrowing, lending and document delivery requests through ILLiad.
March 17, 2004
By ILLiad's seventh anniversary, the system was in use at more than 400 libraries in North America and Asia, including some state-wide library systems. Fifty-four percent of the member libraries in the Association of Research Libraries were using ILLiad. By this date Virginia Tech Interlibrary Loan had processed 540,000 borrowing, lending, and document delivery requests through ILLiad.
October 22, 2004
OCLC announces that ILLiad is licensed to libraries in all 50 states.
March 17-18, 2005
First ILLiad International Meeting and 8th anniversary celebration, Dublin, OH. By this time, Virginia Tech had processed about 616,000 borrowing, lending, and document delivery requests using ILLiad. Also, by this time ILLiad was installed in more than 600 libraries, and 42% of all OCLC ILL traffic originated in ILLiad systems.
January 12, 2007
ILLiad was in use by 784 libraries at the beginning of its tenth anniversary year. Of the 123 members of the Association of Research Libraries, 70% were using ILLiad. Since July 1, 1997, Virginia Tech had processed 755,760 interlibrary borrowing, lending, and document delivery requests through ILLiad. Since 7/1/1997, Tech had borrowed a total of 232,828 items from 3,078 libraries for 19,327 students, faculty, and staff. (Note that these 3,078 distinct OCLC library symbols correspond to 3,851 unique library addresses because some OCLC symbols are used by multiple libraries in a system.) In addition, since 3/10/1999 when ILLiad lending was launched, Virginia Tech had loaned 188,140 items to 4,207 libraries. (Note that these are 4,207 distinct OCLC library symbols corresponding to 5,539 distinct library addresses.)
