intervals. It is better to spend an income of $600 per year in monthly
installments of $50, than it is to buy twice a year $300 lots.

The frequent purchase will bring you the new and talked of books while
they are fresh in the minds of people, and there is greater economy of
time in cataloging and shelving them.

Second-hand books are rarely cheap at any price.

Have confidence in your agent, for your interests are always his.




CHAPTER XVII

Ink and handwriting


For catalog cards and all other records use a non-copying black,
permanent ink. Carter's record ink is good. It has been adopted, after
careful investigation, by the state of Massachusetts for all official
records. The New York state library school, at Albany, has issued a
little handbook on "library handwriting," which recommends Carter's
record, and says they use Stafford's blue writing ink for blue and his
carmine combined for red.

For all labels on the outside of books, and for all writing on
surfaces which may be much handled, use Higgins' American drawing ink,
waterproof.
