ELECTRONIC MAIL FACTS
Electronic mail is considerably more convenient than regular mail, but there are some limitations. The most important limit is capacity. Unlike a post office box, your electronic mail box cannot expand in size. Every electronic mail box has limits imposed by your electronic postmaster. The size of the box is limited to a pre-defined capacity expressed in bytes. Each electronic letter has a different size based on content and the number of links it has passed through on the way to your mailbox. Letters stay in your mailbox until your e-mail software removes them.
In addition to limits placed on the size of the mailbox, each service provider (ISP) has placed limits on the size of files it will put into a mailbox. Typically these file sizes are large enough to pass most letters but not large enough to pass graphic attachments such as pictures and manuals. Our manuals are scanned as high quality graphics rather than text; therefore, their file sizes are usually large, and they can not be compressed any more than they already are.
Before requesting electronic delivery, please check the file size listed in the catalog. If we have not yet listed the file size, please call or e-mail to check the size. Add at least one third times the listed file size for "net overhead" and make sure that your mailbox is empty. If the file size is not yet listed please inquire about the size. We will always be glad to send you a paper copy ( + mailing charge) if the transmission fails.
