Brown makes no requirement for deposit or for printing. Harvard provides that one copy either printed or written must be deposited in the library. Yale requires that the "thesis must be deposited at the library for public inspection not later than May 1st" of the year in which the candidate expects to receive the degree. Of these universities two only, Brown and California, print the titles of theses in the university catalog. The foregoing statements are taken from the annual catalogs for 1899-1900 of the universities named, except in the case of Pennsylvania, where the statement made in the catalog is supplemented from a letter received from the Dean. Although I presumed that most of the copies deposited in the libraries of the universities were used for exchange, I wrote to the librarians of those universities which require the deposit of a number of printed copies, making inquiry regarding their systems of exchange and provisions for the sale of copies not exchanged. I received replies from almost all. [These letters were read, the common condition being shown to be that most of the copies received by the libraries were exchanged with foreign institutions and other American universities. Varying conditions ranging from a refusal to sell any copies to a free distribution of copies not exchanged, was found to exist with regard to sale of theses by the libraries.] It will be seen from these replies that, if a library does not happen to be on the exchange list of the university in which a thesis is written, and if the thesis is not printed in some journal or in the proceedings of some learned society, such a library stands very little chance either of learning of the publication of a thesis or of procuring it from the author or from the university. That this is not much of an affliction in most cases I cheerfully admit. Still the small colleges which deliberately refuse to attempt graduate work--and, be it said to their honor, there are not a few of these--and the large reference libraries which do not publish, have as much need of certain theses as the large universities, and they have no means of getting them easily.
