Interlibrary Loan




Without interlibrary loans, if a library patron found an item they wanted, they would have to travel to that library, and apply for a local Library Card if eligible, or present a reciprocal card in order to borrow the item. By taking advantage of interlibrary loan, in comparison, the library staff can search large numbers of libraries at once, transport the item from several miles to thousands of miles away, and allow a patron to borrow the item using their local library card.


HOW INTERLIBRARY LOAN WORKS


Interlibrary loan is conceptualized in terms of borrowing and lending.
  • A Borrowing Institution is requesting an item for use.

  • A Lending Institution is filling the request of the Borrower.

  • Most institutions both borrow and lend.

  • Commercial document delivery services can borrow on behalf of anyone willing to purchase the information.


In some instances, one librarian is in charge of borrowing and another is in charge of lending; this varies by institution. Some computer programs used to manage interlibrary lending include Ariel, Clio, and Odyssey.

Loans between branch libraries in the same system may take one or two days, while loans between library systems may take a week or more to be delivered. If an item is rare or difficult to find, this may be the easiest way to gain access to it. However, if an item is rare or difficult to find, interlibrary loan does not guarantee that the lending library will send the item to you through your local library. Some collections and volumes may be non-circulating. ''Urgent requests'' are placed if the item is needed urgently. These requests should be prioritised and supplied quickly. Books may be posted by courier and photocopies may be faxed or scanned and sent electronically. Additional fees may be charged for urgent service.


HISTORY OF INTERLIBRARY LOAN


Traditionally, library users discovered potentially useful titles from book advertisements, through word-of-mouth from a friend or an authority on the subject, consulting the Bibliographies found at the back of books or published as a separate book, or a printed Union Catalog of all the books in a group of libraries such as NUCMC . Since the mid-1980s, searching for books located at other libraries has become easier, as many libraries have allowed library users to search their Online Catalogs at the library or over the Internet .


RESOURCE SHARING NETWORKS


Libraries have formed voluntary associations with each other to provide an online union catalog of all the items held by all member libraries. Whenever a library adds a new item to their own catalog, a copy of the record is sent to update the union list. This allows libraries to quickly find out what other libraries hold an item, and software can facilitate the requesting and supplying of interlibrary loans. In the U.S., OCLC (Online Computer Library Center) is usually used by public and academic libraries, and RLIN (Research Libraries Information Network) is used primarily by academic libraries, although some libraries are members of both. Australia and New Zealand use Libraries Australia and Te Puna respectively, the national bibliographic networks of those countries.

Libraries that do not belong to a network can participate in interlibrary loan by making the arrangements by postal mail, fax, email or phone. Requests placed in one of these ways are referred to as ''manual requests''.

Libraries may also have reciprocal arrangements with each other in order to supply loans and copies for free.


USEFUL INFORMATION FOR INTERLIBRARY LOAN USERS


  • Interlibrary loan policies will vary from country to country and library to library; always check your own library's policy with library staff.


  • If an item is not available from libraries in your own country, it might be possible to get it from another country, although this may be more difficult. Neighboring countries should be tapped first for faster turnaround time.


  • Insurance and shipping charges may be an issue regarding loans from other countries. Check with the interlibrary loan staff regarding questions on these charges and whether any costs will be passed on to you.


  • If you frequently use ILL, you might not get items every week. You might get many items one week and almost no items the next week, since turnaround time varies depending on a number of factors.


  • The OCLC First Search WorldCat Database is the best place to look for Interlibrary Loan items, and your local library probably has an online "order form" to use to obtain the items, although some libraries in rural areas may still have print order forms.


  • Many books published in Latin America are owned by the University of Texas in Austin. (They have one of the biggest Latin American libraries in the U.S.) Books regarding Alaska or the Polar Regions may come from Elmer Rasmusson Library at the University of Alaska Fairbanks. University of Manoa in Hawaii has the largest depository of items regarding the Pacific Islands but, if on the mainland, it is usually not possible to get items from there.


  • Providing the results of your own searching of online catalogs may be useful for the library doing the interlibrary loan for you but your library may obtain your loan from somewhere different if they have their own systems they prefer such as reciprocal arrangements that cost less.


  • A rare book may be hard to obtain, but there is a chance that more than one library may own a copy. Some may loan their copies while others have policies restricting lending of rare materials. Interlibrary loan departments will usually try to obtain most requested items even if a title is considered "rare". Rare items may only be available for reference use in the borrowing library, however.
