Students who haven't enrolled for
classes but have elected to stay in Ann
Arbor this spring and summer might
be surprised when the gatekeeper at
CCRB turns them away or the doctor at
Health Service hands them a bill.
These and other "no-cost" student
services are currently being provided
exclusively to students in possession of

ACCORDING TO Central Campus
Recreation Building clerk Valerie
Wenger, students currently enrolled in
classes pay for the use of the facilities
through their tuition costs. Non-
enrolled students have not paid this fee,
she continued, and thus are not entitled
to the same privileges.
Wenger added that non-enrolled
students can purchase a student pass
for $10, entitling them to use CCRB
Health Service denies non-enrolled
students its services for- the same
reasons as does CCRB. According to In-
terim Director Anna Davol, however,
student health care rates ranging from
$10 to $15 are available.
CHECKING OUT books at the
libraries is another privilege denied to
non-enrolled students. Library Director
Richard Dougherty said denial of this
fringe benefit pis not related to a
student's tuition payments, but rather
stems from long-standing University
policy which dictates that certain ser-
vices, such as library use, are not to be
provided to non-enrolled students.
Rose-Grace Faucher, director of the
Undergraduate Library, said recom-
mendations were made by a library
staff committee to extend additional
services to non-enrolled students but no
word on the recommendations has
come from the University ad-
ministration as yet.
The library presently has no policy
enabling non-enrolled students to pay a
fee in order to use the facilities,
Students may also obtain access to
recreational buildings and Health Ser-
vice by paying a registration fee of
$42.42 at CRISP, the official said.
