To determine single-piece weight in any mailing of nonidentical-weight pieces, weigh each piece individually. To determine single-piece weight in a mailing of identical-weight pieces, weigh a sample group of at least 10 randomly selected pieces and divide the total sample weight by the number of pieces in the sample. Express all single-piece weights in decimal pounds rounded off to four decimal places.
The Library Mail rate is charged per pound or fraction thereof; any fraction of a pound is considered a whole pound. For example, if an item weighs 4.225 pounds, the weight (postage) increment is 5 pounds. The minimum postage rate per addressed piece is that for an addressed piece weighing 1 pound.
Barcode Discount. The barcode discount applies to Library Mail machinable parcels (see 101.3.3) that are included in a mailing of at least 50 pieces of Library Mail. The pieces must bear a correct, readable barcode for the ZIP Code shown in the delivery address as required by 708.5.0, Standards for Postal Routing Barcodes.
For barcode discount for single-piece rate, deduct $0.03 per parcel (machinable parcels only, 50-piece minimum). See Exhibit 1.5, Library Mail Rates.
For each piece, affix the postage for the weight increment as shown in Exhibit 1.5.
The USPS does not guarantee the delivery of Library Mail within a specified time. Library Mail might receive deferred service. The local post office can provide more information concerning delivery times within its area.
Library Mail is not sealed against postal inspection. Regardless of physical closure, the mailing of articles at Library Mail rates constitutes consent by the mailer to postal inspection of the contents.
All Library Mail must bear a delivery address. The delivery address on each piece must include the correct ZIP Code or ZIP+4 code. Alternative addressing formats under 602.3.0 may be used. Each piece must bear the sender's return address.
Mailable matter meeting one of the specific eligibility standards in 3.3 or 3.4, as applicable, and that is neither mailed or required to be mailed as First-Class Mail nor entered as Periodicals, may be mailed as Library Mail.
Each piece must show in the address or return address the name of a school, college, university, public library, museum, or herbarium or the name of a nonprofit religious, educational, scientific, philanthropic (charitable), agricultural, labor, veterans, or fraternal organization or association. For Library Mail standards, these nonprofit organizations are defined in 703.1.0. Only the articles described in 3.3 and 3.4 may be mailed at the Library Mail rate.
The items described in this section may be mailed at the Library Mail rate when sent between: (1) schools, colleges, universities, public libraries, museums, and herbariums and nonprofit religious, educational, scientific, philanthropic (charitable), agricultural, labor, veterans, and fraternal organizations or associations; (2) any such institution, organization, or association and an individual who has no financial interest in the sale, promotion, or distribution of the materials; or (3) any such institution, organization, or association and a publisher, if such institution, organization, or association has placed an order to buy such materials for delivery to itself:

Markings that have the character of personal correspondence require, with certain exceptions, additional postage at the First-Class rates. The following written additions and enclosures do not require additional First-Class postage:
h. Manuscripts accompanying related proof sheets and corrections of proof sheets including corrections of typographical and other errors, changes in the text, insertions of new text, marginal instructions to the printer, and corrective rewrites of parts.
An invoice, whether it also serves as a bill, may be placed either inside a Library Mail piece or in an envelope marked "Invoice Enclosed" and attached to the outside of the piece if the invoice relates solely to the matter with which it is mailed. The invoice may show this information:
Incidental First-Class matter may be enclosed in or attached to any Library Mail piece without payment of First-Class postage. An incidental First-Class attachment or enclosure must be matter that, if mailed separately, would require First-Class postage, is closely associated with but secondary to the host piece, and is prepared so as not to interfere with postal processing. An incidental First-Class attachment or enclosure may be a bill for the product or publication, a statement of account for past products or publications, or a personal message or greeting included with a product, publication, or parcel. Postage at the Library Mail rate for the host piece is based on the combined weight of the host piece and the incidental First-Class attachment or enclosure.
