What items cannot be requested or are difficult to obtain through Interlibrary Loan?

We cannot borrow: Rosetta Stone; any downloadable or streaming formats, such as eBooks and eAudiobooks (though we may decide to purchase electronic content); entire issues of journals and periodicals (we can obtain articles). Microfiche, microfilm and genealogy materials are challenging to obtain. Additionally, we will not borrow through Interlibrary Loan any item already in our collection. We will do our best to locate the requested item, though finding a library willing to lend it is not guaranteed.
