Notify other libraries taking advantage of local listserves or individual e-mail. Remember, we are trying to save paper. Book Vendors Contact your major vendors or used book dealers. Some vendors purchase used books or credit your account. For best results try to match your offerings to the unique collecting habits of each vendor.
Some library associations organize committees to facilitate exchanging library materials.
The American Association of Law Librarians' Technical Services Section has a duplicate exchange committee which handles mostly journals, and once a year, treatises are exchanged. Many countries are in dire need of reading material. Even if the native language is not English, foreign libraries often welcome books that will give patrons the opportunity to practice English. I have sent large shipments of books to Mexico, Ireland, Poland, Nigeria, Cameroon, and Bulgaria. Contact the acquisitions or gifts librarian at the largest academic library in your state or area for foreign donation information, as this is often coordinated through the above mentioned exchanges.
