I recently went to a library book sale and some of the books have the library's name & address stamped on the first page and on a couple of pages in the middle of the story (page edge).  Is this acceptable?  This is what I find from the help center and am not sure if it includes pages within the middle of the book.

Ok let me get this right. The markings are on the outside of the book or on the inside first page?

Do the stamps or their markings impact the text at all, or are they just in the margins?

The first inside page and could be on page 30 and page 150 (edges, usually at the bottom by the page number).

The books that I've checked, the stamps do not cover up any part of the story (on either side.....as it was covered by permanent marker and shows through the other side of the page).

Decirculated library books may have various markings and/or stamps inside or outside or on the page edges of the book; this is OKAY.

They are fine.  This statement would include anything a library does to a book to process it, have it circulate, and be withdrawn would be all the things you are wondering about. 

Libraries often put a stamp somewhere once of twice in the middle on the book in the margins.  It's for security.  It's too easy to rip out the first page if it's got a stamp, but not so easy to find them all within the text.  Another thing that libraries do is put on security tape in the spine for hardcover books and a security sticker within the pages of the text. 

Hi, I'm new around here and just posted my first books. I was checking out the forums and stumbled across this. I'm glad you posted this because quite a few of my books are ex-library books purchased at book sales. They all have stamps, markings in various places but none interfere with the reading of the book. I'm glad to see that this is ok.

You might want to PM the person before you send just to make sure.  The library stamps might not be an issue but the black marker on text pages might bother some people. Does it cover the text on the back of the page where the marker is?

Here's another question about ex-library books.  Obviously if the wear and tear from the books library days is excessive "cleaved spine, water damage, etc.", then the book is not postable.  What about damage other than stamping from the withdrawl process?  For example, sometimes the library removes the card pocket (from books that still had them), thus damaging the inside cover.  Or they cut out the security bar, leaving a hole in the protective clear "plastic" that often is put on paperbacks.  Or reinforcing tape is added to the inside front and back covers.  Would these types of things make a book unpostable, or is that just part of the ex-library book package?

Those all sound fine to me.

I think those are all just ex-library things to me and I would not care about receiving a book like that.  If people do not want ex-lib books, then it should be in their conditions.

I do think that it is a good idea to PM the requestor prior to sending out the book.......even if the requestor does not list any conditions.  It will save the time and headache of them marking the book "received with a problem".

Removing the pockets shouldn't be a problem.  A lot of libraries have books circulating with the pocket removed.  This should be fine because it's the normal wear & tear one would expect to find on a library book. 

In my 14 years as a librarian, I have never seen a library cut out security tape / stickers.  All libraries are different, though.  Just think of the time used to cut out barcodes and the like when a thick black marker through the barcode serves the same purpose.  A lot of libraries don't even use a marker to cross out the barcode; some don't even stamp the books as "Withdrawn."

I sent an ex-library book out just a few weeks ago that had the security sticker thingie cut out and the requestor marked it as received with a problem and chose the "damaged by sender" option.

I thought the book was fine, read it and enjoyed it, but he had a problem with the cut-out, I guess. It irritates me that this caused my very first damaged book. I'd really like to know from the powers that be if this cut-out is allowed or not. I have two other books that were all bought from the same library sale and they both have the cut-out. They're both wishlisted, but I'm afraid to list them now. I'll probably just give them to friend's here.

Ange, my library is a teeny-tiny country library and it seems like they have lots of free time to cut up books! I wish they didn't have time to do this to the books! LOL

I would think that it is okay to send it because A) it's okay to have the cover torn or missing up to an inch and B) it's okay to have the corner snipped off the way used paperback stores do to their books. 

So the book you sent, Valli, should be okay as long as the cut out was an inch or smaller.

The guidelines here say that a name plate on the inside cover or on the first page is okay.  Substitute circulation pocket for name plate...

You think your library has free time to cut up books?  One of my smaller libraries used to "clean" all the children's books with wipes like Windex, Mr Clean, etc when they were returned !!!

Valli:  you could put a post in book bazaar saying you have those 2 WL books and explain about the ex-library cut out. I bet someone with them on WL will let you know they don't care about that.  Then you can post them direct to their WL.
