h with
care for missing pages, and injuries of any kind. Imperfect volumes
are returned. But save with very expensive books this labor is
unnecessary, and doesn't pay. The time spent on it easily amounts to
more than the cost of replacing the very few books which may by chance
be later found imperfect. In fact, any responsible dealer will usually
replace an imperfect copy with a good one even if the former bears a
library mark, and has been handled a little.

Use care in cutting pages. Don't cut them with anything but a smooth,
dull edge. Cut them at the top close to the fold in the back.

The worst enemies of books are careless people.

Another enemy is damp. It is bad for the binding; it is very bad for
the paper.

Gas, with heat, is very destructive to books, especially to the
bindings.

Books should occasionally be taken from their shelves and wiped with
a soft cloth. The shelves should at the same time be taken down and
cleaned thoroughly.

Don't hold a book by one of its covers.

Don't pile up books very high.

Don't rub dust into them instead of rubbing it off.

Don't wedge books tightly into the shelves.

Those who use a public library are all desirous that its books be
clean and neat, and with a little encouragement will take pretty good
care of them. There are exceptions, of course, and especially among
the children. These must be looked after and reasoned with.

Don't cover your books. The brown paper cover is an insult to a good
book, a reproach to every reader of it, an incentive to careless
handling, and an expense without good return.

A few simple rules like the following can be brought in an unobtrusive
way to the attention of those who use the library. Always be sure that
the library sets a good example in its handling of books.

Keep books dry.

Do not handle them when the hands are moist; of course never when the
hands are soiled.

Use them to read, and for nothing else.

Never mark in them.

Do not turn down their pages.

Do not lay them face downwards.

Do not strap them up tightly.

Never let them fall.

Open them gently.

The book you are reading will go to others. Pass it on to them neat
and clean, hoping that they will do the same by you.

CHAPTER XIX

Accessioning books

A careful record should be made of all books received. Use for this
purpose what is called an accession book. This is a blank book, ruled
and lettered and numbered especially for lib
