When you order please be sure to put down both the file number and the complete OB title, especially the date.
Material is printed out by file number.
The title is necessary if I am to resolve problems when the computer tells me a file number is bad. If your handwriting is not clear, errors can result in the filling of your orders. Use only capital letters when you fill in the file number. These errors can be eliminated by downloading the catalogs and editing a copy to list only what you want. Also, to facilitate our filling your order, please try to keep the files you order in the order in which they appear in the catalog.
