RFID sounds like it will make my job much easier....?

From what I have learned about RFID I think it is one technology that will most improve libraries for the librarians. The idea of having "smart shelves" sounds incredibly enticing. I hate that I can look up a book in my library's catalog and go to the shelf (cause it says it is there) and guess what, its NOT THERE! So I look all around the shelf, I look on the shelving carts, I go back and check the catalog again and then I go back and check the shelf again, still nothing...I go back to the catalog and see it may be at another nearby branch, I call the branch, they do a shelf check, I wait on the phone with the patron breathing down my neck, desperate for the book because their child's book report is due tomorrow....and it is not at the other branch either...sigh....
I do this how many times a week? Or because I am a children's librarian I collect books during the week for storytime and outreaches to schools. I find the perfect book in the catalog for my storytime or class visit and I go to the shelf to retrieve it...dammit...sorry but that is honestly my reaction, albeit a quiet reaction as children and students are around (I work in a joint middle school/public library). I just think the idea of having shelves that always know where a book is sounds AMAZING! A shelf that will keep track of every time someone removes a book, even if they put it back in the same place! AAGGH! That's a happy scream by the way. I can't imagine how great RFID would be in a bookstore as well (I used to work in a Barnes & Noble, their problems are not always so different from ours in a library). Think about it! No more shelf reading, no books out of place on the shelf! I can't help but think how it could improve access for patrons too but I'll stick to the advantages for librarians.
The RFID tag would make circulation activiites incredibly more efficient as well. Check-in and check-out would be faster as the tag could be scanned in any direction. I sit at our check-out desk and have to try and scan those barcodes several times before they take, you have to hold the barcode just in the right position before the "gun scanner" will take it. Also, you can scan multiple books at once for check-out, how fast would that be! Fast I bet.

RFID would reduce staff time for circulation activities and shelf reading. Customer and collection records could be automated in real time. RFID would also help improve circulation statistics and give libraries a better view of what their community needs are based on those circulation stats. RFID tags would also control losses and serve as a security device as RFID tags could include a built-in security feature that would be more reliable than some of the traditional security methods libraries use such as metallic strips in materials and sensor gates. Since RFID would provide more accurate information about availability of materials patrons would be happier and then librarians would be happier!
