“…Increasing the output power generally increases the reading distance (Daim and Lee, 2009) for UHF tags. This relation does, however, not apply at certain distances, and the range can decline at increasing power (Hoong, 2007).…”

“…The output power of the inventory reader determines the read range. The higher the output the longer the read range is, although this relationship seems not valid at all distances (Daim and Lee, 2009). The output power is limited by legal limits for health and safety reasons (TagSys, 2006), the higher the output the larger the battery needed or shorter the battery life.…”

PurposeLow read rates are a general problem in library inventories. The purpose of this study is to examine the factors that contribute to the success of library inventory by means of a radio-frequency identification (RFID) inventory taker. The factors investigated were tag position, tag orientation, book thickness, tag density (related to thickness of a sequence of books) and position on the shelf.Design/methodology/approachA total of 210 books were placed in eight random permutations on three fixed book shelves. For each configuration, the RFID tags were read forty times. The resulting data were analysed by means of a generalized linear model, relating the combined contribution of tag position, tag orientation, book thickness and position on the bookshelf to the read rate.FindingsThe tags positioned directly next to the spine were always read, but those near the opening of the book (far from the spine and inventory reader) were not always read. Considering only books with tags near the opening, tag orientation and position on the shelf appeared not to be related to the read rate, while book thickness, thickness over three books and spine tag density appeared to have a small positive contribution to the read rate.Practical implicationsLow read rates during a library inventory can be prevented by placing the tags near the book spine – the other book specific factors (listed in the previous paragraph) are of little influence. When not scanned during a first sweep, repeated scanning can increase the read rate with 0.15.Originality/valueThis paper is one of the first to analyse the influence of tag location and book specific factors on the read rate of RFID tags in library books. The experimental approach sets an example for future work.

“…According to the idea of LANDMARC system, this paper uses pattern matching method based on received signal strength (RSS) to positioning books, that is the nearest neighbors algorithm [11] . Intelligent bookshelf designed in this paper need to be installed a reader in each shelf, thus every intelligent bookshelf is an independent real-time location system unit.…”

Abstract-Under the currently trend of the library collection quantity increasingly, the book disordered problem became more common which caused the reader too hard to find a book that they want. To solve these problems, this paper design the accurate location algorithm based on RFID intelligent bookshelf, and set the algorithm model parameters. Through the simulation analysis , the location algorithm improves the positioning accuracy effectively , lower the system cost complexity, improve the borrowing efficiency of the readers.
