Here's what we have received so far. *We started out as a pack library.  We purchase our own envelopes if we run out.  We then went no-pack and within a few weeks had more items coming back with banged up corners, gouged covers, etc.  We then switched back to pack and I am glad.  It seemed we were always submitting a complaint or request for payment to Rides.  The problem we ran into after we switched back was that libraries returning items to us had printed the MeL straps or labels ahead of time and it showed we were no-pack.  So we had to ask Sue to remind libraries to be aware that libraries may change their preferences and to be on the look out.  Don't get me wrong, I think having the option is great, but our items were getting damaged and it was cheaper for us to purchase envelopes than replace books. Hope this helps! *Hi Loretta, we've been no-pack for a number of years. We love it! * Not much damage at all, mainly to larger, skinny paperbacks that curl if people use hefty rubber bands. * Do realize, though, that RIDES won't reimburse for lost no-pack items, only AV.  As we use a local delivery system instead of RIDES, it's a moot point for us as each system tends to blame the other for everything!  Can't say that we've lost many items either, though. * We have put a few new envelopes into the system, but I can't say we've needed to do it often.  In fact, we've offered up bundles of envelopes in the past when they've stacked up past what we can store.  Some libraries will send your items back packed regardless, so I think that's where we gain them... * Boxes for AV are another story.  We box all AV (our own and others') just to be safe.  However, as MeL allows envelopes for AV packing you could go that route if you wish.  Boxes, though, definitely prevent almost all AV damage so it's a nice thing to do if you can afford it.  We use Uline for our boxes, but I'm sure there are other options out there. * I think many libraries use the system of 2/page labels for no-pack and 6/page for pack (you might already do this), and it usually doesn't let us down. * If you do switch, we've found it is safest if you stick one end of the larger label inside the book, fold it over the cover, and then use at least 3 rubber bands to secure. *We're no pack.  Huge time-saver.  I don't see things coming back damaged. *I was a little leary of moving to no-pack, but it has worked out well.  There have been a few damaged items, usually CDs which weren't packed.  I'm rarely low (or have too many) envelopes. It has saved us a lot of staff time. *We are a no-pack library. Made the switch from pack about two years ago. We have lost maybe two books to damage in all that time.  I think for a public library, no-pack is the way to go.  Needless to say, we save a lot on packaging materials and it's better from a workflow standpoint also. *We have always been no pack and had no problems; in fact I wish everyone were except for AV and obviously fragile items like pop ups. We bought a few DVD mailers early on but have never needed to purchase anything else. *In our area packing envelopes can not be recycled so we put out the word to our patrons that we recycle packing envelopes and our patrons bring bags and boxes of them to us. We have never had to purchase envelopes and are often giving boxes of them away because we end up with too many.  Patrons also appreciate that we reuse them. *We are a no pack library.The con is that if something is damaged or lost in transit you are not eligible for reimbursement.The big pro for us is time savings.We do a large MeLCat volume.It is much more cost effective for us in terms of staff time vs. the occasional cost of a lost/damaged item. *Hi Loretta Cadillac Wexford Public Library is NO PACK, and we have been almost from the beginning of our participation in MeLCat.  We experience very little damage from RIDES issues, and what does happen certainly doesn't equal the extra cost of packaging materials and the staff time to pack non AV items.  We try to re-use the materials we receive from packed items for the items we need to send back packaged, so need to buy very few supplies: mostly tape and sometimes rubber bands.  I hope this information is helpful. *Hi Loretta, I passed your query to my staff who handle our MEL's and here is a response: *"We have been very happy being a no-pack library. The time it saves is immeasurable and it also saves paper and space in our bins. Also, after being no-pack since the beginning, we have had no problem at all with material being damaged. Hope this helps" Have a great Tuesday! *We have been a no pack library for about 10 years and less than a handful of books have actually been damaged. I must say it is very nice not having to place our books in envelopes and saves time for sure. When we switched to no pack I was nervous about items being lost or damaged but I am so glad we did switch. You won't regret it! Whatever you choose there are always libraries needing to get rid of envelopes, we share with other libraries:) *We are an academic library, so we tend to hang on to our holdings for a long time. Largely because of this, we pack, to cut down on damages and lost items. Also, we tape the shipping labels to the package, and we think this reduces potential for shipping errors, due to lost labels, etc. We do purchase some envelopes, and reuse many of the envelopes we receive. If we run short, we will respond to offers for packing materials available, and if we have extra, we offer them on the listserve. All in all, Mel costs us so much less than regular ILL, so we don't worry too much about the envelope costs; we'd be buying them anyway. Hope this is helpful *We here in Allendale are a no pack and I can't recall a single item being damaged, as a result, in my 7 years. *We are a pack library and cannot imagine going any other way.I actually have had a couple of our books returned without packing and they were damaged.Of course I have no idea if it happened in delivery or while the other user had it but usually the borrowing library tells me that it was fine when they send it into delivery. I recycle envelopes from anything that we get in.I purchase movies from Amazon and they come in nice large bubbled envelopes.I just take off the mailing label and voila!Many of my staff have started bringing in their used envelopes too as a way to recycle them.If need be, I have purchased a large box of envelopes from Sam's before too. My biggest frustration with the no pack libraries is how to get the labels on to return them.We have gotten some fairly mean emails from libraries because a little bit of tape has gotten on the cover of their book.We always use removeable tape but apparently sometimes it does damage the cover.We definitely try to not get tape on the cover but sometimes it just feels impossible, we usually tape the rubber bands but.....-we want the book to get back home!! Just my two cents worth— *We have had packaged items damaged, so I wonder if they are more careful with unpackaged items. We usually have plenty of envelopes.  Whenever something arrives to my house in a packing envelope, I bring in the envelope to re-use. -- Loretta Sherfield Branch District Library Interlibrary Loan Department
