It would not be economical to plan a time limit on loans, as usually
the library requesting it states the time the book will be needed and
it is, if possible, loaned for that period. As soon as the library
borrowing it is through with it, even if sooner than the time it
expected to need it, the book is returned. Any book must of necessity
be subject to recall by the library loaning it. There cannot well be
a limit to the number of volumes loaned at any one time. That would
naturally depend upon the need. No fines or other penalties for
negligence in returning loans are necessary where there is a spirit of
perfect co-operation, as librarians all understand the necessity of
system, and in California at least, show great consideration for each
other.
