A librarian's ethical dilemma

I borrow knitting magazines from my public library and thought I had returned 2 issues of Interweave Knits last week. Then I got an overdue notice for one of them and checked my pile of magazines. There it was. I'd returned one of my own magazines by mistake, which is ok since it wasn't one of my favorites. But the library's issue (Summer 2004) has some great patterns -- several bags, a mitered square rug by Katy Ryan, Streaming Leaves Shawl by Cat Bordhi, Cabaret Raghlan by Norah Gaughan, Mosaic Mitts by Sandy Cushman. . . . Apparently I'm not alone in wanting this issue--it's sold out everywhere. I am a librarian, though, so I couldn't just give up. I started trolling the web and found:

• Mitered Square Rug is online at Interweave's free patterns. Success!
• Cabaraet Raglan is included in The Best of Interweave Knits so I may just buy the book.
• Mosaic Mitts is included in Interweave's Holiday Gifts 2006, also sold out but I think I can track this down.

While searching, I found some great websites, blogs and new free patterns, so this was time well spent:

• Cashmere Moebius Shawl and Baby Life-Ring Socks on Cat Bordhi's website.
• Habu Textiles Knit-A-Long blog
• "Is it a sweater yet?" blog archive with lots of pictures and commentary posted by Aven while knitting Cabaret Raglan (Do all knitters have cats? I don't think I've seen a knitting blog that doesn't have as many cat photos as project photos. I don't have a cat.)
• Needle Beetle -- way more advanced than I'm ready for but I've tagged it. (So much to do when I retire. Just 2 years to go)

So, I found only one of the patterns I want. What's an honest librarian to do? I'll return Interweave to the library, after a pricey trip to Kinko's to make color copies. And I just subscribed to Interweave Knits.
