Assistant Dean of the College Karen E. Avery '87 thought she would be receiving just one more woman in her life this week a baby girl that she delivered on schedule Monday.

But with the end of Radcliffe's days as a college, Avery, who is responsible for co-educational issues at Harvard, ended up with more than 3,000 new charges.

Along with other administrators in University Hall, Avery must ensure that Harvard's decision to acquire the 120-year-old institution will not adversely affect undergraduate women who have come to rely on Radcliffe for spring break externships, summer traveling fellowships and a seal on their diploma.

But while pledging to continue to serve the needs of females on campus, Harvard and Radcliffe officials said these and other single-sex traditions on campus are likely to change. Administrators stressed that many implications for undergraduate life were not fully thought out in yesterday's agreement.

"Some things are not at all decided or discussed, especially about under- graduates," said Mary Maples Dunn, who wasnamed the interim head of Radcliffe yesterday.

All Dean of the Faculty Jeremy R. Knowles couldpromise yesterday was that the undergraduateprograms Radcliffe has offered will remainunchanged next year.

But according to Dean of the College Harry R.Lewis '68, Harvard will not make an exception toits non-discrimination policy for the single-sexprograms.

"Whatever happens, the College will maintainits principle that all Harvard programs should beopen to all Harvard students without regard totheir gender," he said.

"I'm sure there will be a transition periodwhere the implications of this agreement withRadcliffe will have to be worked out," he added.

Harvard and Radcliffe officials expresseddiffering opinions yesterday about whetherHarvard, which receives money from the government,would be legally permitted to administersingle-sex programs under federal law.

While the law exempts traditionally single-sexcolleges such as Radcliffe, this exemption may notapply to Harvard.

"If it's okay to have women's sports, is itokay to have a women's student union?" Dunn said."I don't know. I'd have to ask a lawyer, and wewill, I'm sure."

Entrances and Exits

Programs aside, yesterday's agreement willchange the way women enter and exit the College.

Until yesterday, women were officially admittedto Radcliffe College and then immediately enrolledat Harvard, while men were admitted directly toHarvard.

Future classes will be admitted to Harvarddirectly and will no longer have "dualcitizenship" at two colleges.
