can I put on hold future books by an author.
Yes, you can--as soon as the book appears in our online catalog, you can place a hold. It will appear usually as soon as we have ordered it, which may be up to a few months before it is actually available.
You can also suggest purchases, and get feedback on those suggestions, here. (You will be prompted to enter your library card number and PIN first.) That page also includes a list of all the authors whose new books are ordered automatically.
