Postal regulation state that there can not be any personal correspondence in media mail. When I print a label for mailing, a second sheet is printed that give instruction to the sender and the receiver. This second sheet would be considered personal correspondence. The post office has a right to open media mail to see if it meets regulations.

My question is "Has anyone had a problem when sending the second sheet?"  Has anyone had a book returned or received a book with postage due?  Has anyone received a book with a sticker on it that states "this package has been open for inspection".

this is incorrect an invoice or the shipping information is okay

even a card

I have never had any problems you mentioned. And I've always used the second sheet to wrap my books. As far as I know. I've never had any of my books opened by the post office.

You are correct about the invoice, but the letter is talking about what to do on this site.  It's more than incidental material.  If it hasn't been a problem for anyone, then I don't have a problem with it.  I was just wondering if it has been a problem.

This second sheet would be considered personal correspondence. It is not personal correspondence. It is a packing slip and clearly falls under the exceptions to media mail rule. It is not only incidental to the book, it is required to go along with the book since it instructs the receiver on how complete the transaction. 

There has been many instances that members have reported their packages being open and inspected. The only USPS employees that have taken issue with it were uneducated and were quickly corrected.  We also have many postal employees on the site that have posted the part of the MM regs it falls under. 

The site obviously makes sure they are not asking us to include something that would violate postal rules. This is a highly skilled and educated staff running the site, have faith in them, they do their research.

Here is the allowed items part of the reg. I think the a,d and j clearly show the PBS wrapper info is allowed:

4.3 Written Additions

Markings that have the character of personal correspondence require, with certain exceptions, additional postage at the First-Class Mail prices. The following written additions and enclosures do not require additional First-Class Mail postage:

a. The sender's and the addressee's names, occupations, and addresses, preceded by "From" or "To," and directions for handling.

b. Marks, numbers, names, or letters describing the contents.

c. Words or phrases such as "Do Not Open Until Christmas" and "Happy Birthday, Mother."

d. Instructions and directions for the use of the item mailed.

e. A manuscript dedication or inscription not having the nature of personal correspondence.

f. Marks to call attention to words or passages in the text.

g. Corrections of typographical errors in printed matter.

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.

i. Handstamped imprints, unless the added material is in itself personal or converts the original matter to a personal communication.

j. Matter mailable separately as Standard Mail printed on the wrapper, envelope, tag, or label.

Thanks!

Just as an fyi, I stopped sending the second sheet about a year ago to save on paper & ink (since I wrap in recycled paper grocery bags rather than the PBS wrapper), and I have not had any problem so far with a recipient checking the book received.

I don't put the second sheet in anymore since my post office opened a package, saw that sheet and sent it on Priority Mail.  I was furious but couldn't do a thing about it.  I had written nothing at all on it, just the second sheet as printed.  Now, I don't even put a name & address inside the package.

i just cut out the INFORMATION FOR THE RECEIVER box and tape it to the outside of my package... in the beginning i forgot to put the infor in and now i find this soooomuch easier!
