Most library items [2] circulate for three weeks and may be renewed twice, except when an item has been requested by another patron [3], in which case the item will be recalled after the initial loan period. Exceptions to the standard loan period include DVD's, which circulate for three days, and reference [4] items, which circulate for 24 hours. The library also lends audio visual equipment, which have variable loan periods.
