We make every effort to fulfill University of Delaware researchers’ requests, but sometimes material cannot be supplied through ILL or the Article DELivery Service. Here is a common list of reasons, in order of frequency of use, that requests might be cancelled. For more information, please contact the Collections Sharing and Delivery Department.
There are many situations in which Interlibrary Loan staff will try to obtain material from another library, but we are unable to locate a library that is willing or able to supply an item. These reasons include:
Lending libraries’ restrictions: items may be displayed in DELCAT Discovery with a listing of libraries that own them, but it is up to the owning library to decide whether it can be sent on ILL. Some libraries will not lend theses and dissertations, genealogy titles, audiovisual materials, test preparation guides, rare books, and new or popular books, Libraries outside of the United States may be unwilling to lend their materials overseas. Some publishers restrict access to their materials through licenses, and some audiovisual items and case studies are unavailable through ILL.If you need an item that cannot be loaned, you can contact the library that owns it to ask about using the material on site. For items that are currently available for purchase, you may wish to recommend that the University of Delaware Library acquire a copy.
The item does not appear to be held by any library. Some titles are indexed in DELCAT Discovery and Library databases, but no library has appeared to have purchased a copy of titles. This situation is very common with self-published and other titles that have not gone through a peer review process. We recommend contacting the librarian for your topic to find alternate sources for your project.
Conference proceedings. Many papers and posters presented at conferences are indexed in DELCAT Discovery and Library databases, but the proceedings from those conferences may not have been published. We recommend contacting the author directly if you would like to obtain a personal copy: authors’ information is sometimes available in the database that indexed the paper or poster.
Dissertations and theses: Some libraries will not lend dissertations and theses, and some authors do not permit online access to their work for several years after they graduate. If a dissertation or thesis is unavailable through ILL, we recommend contacting the author directly to request a personal copy.
If you still have questions about your request’s cancellation, please contact the Collections Sharing and Delivery Department.

This item is available for viewing in the Special Collections Reading Room. Special Collections largely consists of rare books, archival collections, and manuscripts. These materials, if held by other institutions, generally are not loaned on Interlibrary Loan, and cannot be obtained on ILL as an alternative to using materials within the Library’s Special Collections Reading Room.
