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.
The vertical hand should be used in all library work.

The following rules, with the illustrations, are taken from the Albany school handbook above referred to: Brief rules 1 Ink.
