Unless otherwise noted, these materials are kept in the Portage Library in Houghton. They are not part of the library's regular collection, and they are not meant to be checked out by the general public. Rather, they are lent to our tutors, who in turn use them with our tutees. For the procedures by which tutors can check out materials, see the page called Tutors on this web site.
Many of these materials are checked out for prolonged periods. If you have a high level of interest in an item that has been checked out for a long time, you can ask that it be returned.
