Please do not let this discourage you from using Interlibrary Loan. Most of the time, libraries loan books for free. When charges occur by other libraries, it is usually for photocopying. The cost may range from ten cents a page and up, with a possible one dollar or more handling fee, to as much as a flat fee of ten dollars or more per article regardless of the length of the article. Also, most libraries will not loan whole volumes of journals.
Charges usually occur with articles in journals in the subject areas of sciences and medicine.
An article from a well-known journal will more than likely be available at a library which does not charge.
