3. If you are within reach of another library, search WorldCat (https://www.worldcat.org/) for the book. Enter your zip code to see a list of libraries near you that have a copy. Borrowing policies will vary from library to library, but most will allow you to visit to read or make copies. Contact each library to find out about its policies.
4. If you hold a library card at your local public library, ask the librarians there about interlibrary loan services. Even if they do not have a copy of the book you need, they may be able to borrow it on your behalf.
