wisdom of this provision is very doubtful. A single card catalogue
for each class of copyright work would save an immense amount of
time and error to the public, and to the Librarian in making
searches. Instead of periodically destroying card catalogues, they
should be added to and preserved. As soon as they are destroyed,
instead of being able to make one examination of one part of the
card catalogue, the public will be compelled to examine a great
number of periodically made printed indexes. I therefore suggest
that the words "and thereupon", to and including the word
"intervals," lines 9 to 12 of page 34, be canceled.
As to the destruction of articles provided for in section 59, I
suggest that the section be amended by inserting in line 10 of
page 36, after the word "provided," the words "and with the
authorization of the Committees on Patents of the Senate and of
the House of Representatives."
