Purpose

Low 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/approach

A 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.

Findings

The 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 implications

Low 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/value

This 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.

使用 RFID 棒的图书馆库存：标签和书籍特定因素对阅读率的影响

目的

低读取率是图书馆库存中的普遍问题。本研究的目的是通过射频识别 (RFID) 盘存器检查有助于图书馆盘点成功的因素。调查的因素是标签位置、标签方向、书籍厚度、标签密度（与一系列书籍的厚度相关）和货架上的位置。

设计/方法/方法

总共 210 本书以八种随机排列方式放置在三个固定书架上。对于每个配置，RFID 标签都被读取了 40 次。所得数据通过广义线性模型进行分析，将标签位置、标签方向、书本厚度和书架位置的综合贡献与阅读率相关联。

发现

位于书脊旁边的标签总是被读取，但靠近书头（远离书脊和库存阅读器）的标签并不总是被读取。考虑到只有靠近开口处有标签的书籍，标签方向和货架上的位置似乎与阅读率无关，而书的厚度、三本书的厚度和书脊标签密度似乎对阅读率有很小的积极贡献。

实际影响

通过将标签放置在书脊附近可以防止图书馆盘点期间的低阅读率 - 其他特定于书籍的因素（在上一段中列出）影响很小。在第一次扫描期间未扫描时，重复扫描可将读取率提高 0.15。

原创性/价值

本文是最早分析标签位置和书籍特定因素对图书馆书籍RFID标签读取率影响的论文之一。实验方法为未来的工作树立了榜样。
