The College's top librarian said yesterday that administrators are considering many proposals to restructure the library system, including several recommendations to revamp Lamont.

At a meeting of the Committee on Undergraduate Education (CUE), Harvard College Librarian Richard De Gennaro said the library staff is undertaking an intensive study to help determine its development during the next decade.

While emphasizing that all proposals are still tentative, De Gennaro said that library officials are seriously considering whether Lamont should continue to serve primarily as an undergraduate library.

Forty years ago, when Lamont became one of the first undergraduate libraries in the country, it was widely viewed as a model for other such libraries. But since then, De Gennaro said, changes in library use patterns have led him to think that "the concept of an undergraduate library needs rethinking now."

De Gennaro said that the following proposals are also under consideration:

. Leaving at least a portion of Lamont open 24 hours a day;

. Acquiring more media and electronic facilities in the library;

. Converting the rest of the library's extensive card catalog to HOLLIS.

. Giving significantly less emphasis to Lamont's "browsing collections." De Gennaro said that since book-stores are now widely used for browsing, "such `gentlemen's libraries' are totally obsolete."

In addition, De Gennaro said that library officials are concerned about an inefficient use of library facilities which is causing a shortage of space.

"We have a very serious space crisis...[but] the problem is not that we need more space, but that we need to rethink the purpose of library space in the Yard," he said.

And De Gennaro said that Harvard may move some 400,000 volumes currently housed in a book depository in Allston to another location. Built some 40 years ago, the Allston depository can hold only a fraction of the books Harvard officials had hoped it could.

De Gennaro said that the review project is an attempt to set priorities for all of the Faculty's libraries. He said that the investigation began early this term and will continue at least until June.

Once the study is completed, a committee of administrators, faculty, and library staff will examine its results and consider future strategies, he said.

Lawrence Dowler, associate librarian for public services, said that library officials will try to involve the wider University community in their deliberations.
