Editing Interlibrary loan (section)

==Methods==
After receiving a request, the borrowing library identifies potential lending libraries with the desired item. The lending library delivers the item physically or electronically, and the borrowing library receives the item and delivers it to their patron, and if necessary, arranges for its return. Sometimes, fees accompany interlibrary loan services. 

Libraries can define what materials from their holdings are eligible for interlibrary loan. Many journal or database licenses specify whether a library can or cannot supply journal articles via ILL, with libraries negotiating for ILL eligibility.<ref>{{Cite journal |last=Croft |first=Janet Brennan |date=2005-05-31 |title=Interlibrary Loan and Licensing |journal=Journal of Library Administration |volume=42 |issue=3–4 |pages=41–53 |doi=10.1300/J111v42n03_03 |issn=0193-0826 |s2cid=152664274}}</ref><ref>{{Cite journal |last1=Litsey |first1=Ryan |last2=Ketner |first2=Kenny |date=2013-11-18 |title=Oh the possibilities: ebook lending and interlibrary loan |url=https://www.emerald.com/insight/content/doi/10.1108/ILDS-09-2013-0027/full/html |journal=Interlending & Document Supply |language=en |volume=41 |issue=4 |pages=120–121 |doi=10.1108/ILDS-09-2013-0027 |issn=0264-1615}}</ref>

The [[International Organization for Standardization]] (ISO) developed ISO standards [[ISO 10160|10160]] and [[ISO 10161|10161]] to standardize terminology and define a set of communication protocols between interlibrary loan systems.<ref>{{Cite web |title=ISO 10160:2015 |url=https://www.iso.org/standard/66169.html |access-date=2023-03-12 |website=ISO |language=en}}</ref><ref>{{Cite web |title=ISO 10161-1:2014 |url=https://www.iso.org/standard/66170.html |access-date=2023-03-12 |website=ISO |language=en}}</ref>
