The Inter Library Loan service (InterLibrary Loan, ILL) provides:
If the item of interest is only part of a book (less than 15% of the total pages) and not the whole book => make a request for the document delivery and interlibrary loan.
These are usually excluded from the interlibrary loan:
books in the examination program, journals, dissertations, bibliographies, dictionaries, encyclopedias, material on magnetic or optical media, books purchased with research funds, old books, rare or valuable books belonging to special collections.
The individual libraries can adopt specific solutions regarding this service: see also the library service page.
