From the Collection Development and Management Plan 02.20.2014:
*Legal Aspects of Gifts
“One Internal Revenue Service (IRS) regulation relevant to libraries has to do with gifts and donations to a library or not-for-profit information center. Any library, or its parent institution, that receives a gift-in-kind (books, journals, manuscripts, and so forth) with an appraised value of $5,000 or more must report the gift to the IRS. A second regulation forbids the receiving party (in this case the library) from providing an estimated value for the gift-in-kind. ... Typically, with gifts thought to be worth less than $4,999, the library may write a letter of acknowledgement indicating the number and type of items received. For gifts of less than $250, the IRS does not require a letter.” (Evans, 2012).
