I don't see a Request button for the book I need in Worldcat.
Answer
Please check if the book is an ebook or a print title. You cannot request ebooks through Interlibrary Loan. Print titles should have a Request button if we don't own the book or it's not available from the Brown Library at this time. Ebooks will not have a Request button. The format of the book can be found right under the author's name in the short record.
