Library Operations incorporates RFID tags and barcodes

Tri-State Tape & Label, Beverly, NJ., worked with Bill Bewlay at Leeming Management Systems, Somerset, NJ, and others to set up the system and integrate the barcode and RFID readers with the library's existing database.

First, the old barcode label in each book was scanned to pull up the data associated with that book. Then the book's new RFID tag was read, integrating its pre-programmed number with the book's database information and old barcode number. Simultaneously, reading the tag instructs the SATO printer to produce a new bar-coded label with the new RFID tag number in Codabar barcode symbology and in humanreadable characters.

The SATO CL408e thermal transfer printer produces the 14-digit Codabar barcode symbol on a white film label, along with the library's name and logo. TriState sales manager George Righter chose the SATO printer for the job because of its reliability.

"In my experience SATO products are the most reliable out there. When I put a SATO printer in a place, I don't have to worry about it. When it does need service, it is very easy to do. SATO printers are very user friendly and very durable," says Righter.

The price is right too, he says. " The pricing is very, very reasonable. They have the best value. I can go on and on about the value of SATO printers."

TriState selected white film for the label, rather than standard paper stock, for longevity and durability. The labels have an interior die cut 1/4 inch around the perimeter of the label allowing that portion of the liner to be pulled away to expose a special adhesive. This archival adhesive doesn't yellow, keeping the label appearance clean and sharp. The 2.5-inch square label is manually affixed over the RFID tag on the inside book cover. The label looks like any standard plate label on the inside cover of a book. It is difficult to remove and disguises the chip underneath.

With the assistance of epixtech in Provo, UT, the RFID reader ties into an automated library system. Now, when a clerk passes a book over the RFID reader pad, it reads the same number encoded in the barcode on the SATO label. Simultaneously, the tag is turned off, to allow the book to pass through the exit reader, and the library's inventory is adjusted to record the item as checked out, to whom, the date and when it is due back.

"It typically takes 30-40% less time to check out materials now. People aren't opening and closing the book and reading the barcode with a wand. They are just moving the book over a pad. The movement is smoother, faster, very efficient and very accurate," says Papai.

So why is the barcode still on the label? While the branch has switched to the new RFID system, the main library is still using a bar-coded checkout method. Books can be exchanged between the different facilities, so both technologies must be used together until the main library is converted in 2001 or 2002, says Papai. It's a good example of two technologies and multiple vendors working side by side to assist each use.

"The different companies have been extraordinarily cooperative to resolve any problems," Papai says. While many libraries use an RFID system to make sure only checked out books leave the library, the Farmington Community Library system has added other applications. Soon, the library system will expand the RFID tag applications to inventory control use and for book returns.

Using an RFID wand, library workers can record what books are on its shelves just by walking down the aisles of books. "Typically, libraries do not have time to do inventory. It is tremendously time consuming. This is great, however, because instead of handling each book, you can just walk down a section of an aisle and the computer wand reads it. You don't have to point it because it’s multidirectional, so it takes both sides of the aisle. It’s just remarkable," says Papai.

The biggest test, however, will come by 2002, when the main branch is renovated, nearly doubling the size from 38,000 square feet to 74,000 square feet. Papai expects an automated material handling system to meet the anticipated increase in use with only minimal staff increases. When the main library's renovation is completed, returned books, both from the outside drop-off box and those returned inside will go on a conveyor. The books will pass through readers that will send them to specific sections of library carts for eventual return to shelves by library staff.

"It will totally eliminate manual check in and sorting of books. That will be effective for 90% of materials that come back to us," says Papai.

"We're also considering applying this to more than books and library materials. Every organization has to be responsible for fixed assets. There's no reason we can't put tags on tables and chairs and then just walk through a room with an inventory reader. No more searching for tags on a table," says Papai.

As in industrial uses of bar-coded and RFID tagged systems, Papai would like to see the barcode label or RFID tag installed at the point of origin--when the book is published. She'd also like more information stored on each tag. Says she, "I'd like to see author, title, copyright date, ISN number and retail price stored on the tag. If I had all that information, then I wouldn't have to key it into my system. I'd save a tremendous amount of time."

Concludes Papai: "This is definitely one instance where public institutions can learn from industry and apply the same efficiency standards to a government operation."

And maybe, an instance where industry can learn from a visionary government institution once thought of as dark and stodgy.
