Using Open Data to Inform Public Library Branch Services

Abstract

This article describes the curation and use of open demographic data to inform public library services. A case study of census data curated for the Seattle Public Library (SPL) system is described. To understand the information needs of library branches, a set of SPL regional managers were interviewed, a set of use cases were created, and a prototype dashboard tool using open census data was developed to address the needs of two SPL regions. The utility of available open data to meet the needs of regional managers is reviewed, as well as the potential development of replicable data analysis tools for keeping public libraries aware of shifting neighborhood demographics.

Research on Automatic Recognition Technology of Library Books Based on Image Processing

“…As shown in Figure 2, phase discontinuity refers to the sudden change of image intensity from one initial value to another, and line discontinuity refers to the sudden change of image intensity from one initial value to another, and then restores to the initial value. In reality, the low-pass filtering function is introduced by the sensor, and the two discontinuities are shown as slope edges and roof edges [15].…”

“…Usually, TH/TL is between 2-3. Using the two boundaries of the gradient magnitude image M(x, y), the strong edge is obtained according to formula (14), and the weak edge is obtained according to formula (15):…”

The Effect of Digitizing Library Services and Facilities on User Satisfaction

“…However, in its application, there are several problems, namely some centralists are less friendly in providing services (greetings and greetings), the lack of implementation of a self-service system both in borrowing and returning books, the number of visitors, especially students who are not familiar with the OPAC (Online Public Access Catalogue) application, which causes most people to be more likely and happy to find information or books through other digital searches such as Google compared to those looking for reference materials in libraries (Hardyanto et al, 2018). In addition, other factors cause people to be less happy to visit the library including the lack of book collections, the number of books loaned is limited, the community's understanding is less about the library, or even the services provided by the library, not by the needs of users, this is shown by the number of users who complain of difficulties in browsing book collections or scientific works because the library has not yet facilitated more computing devices that can be used in accessing digital library services (Ostler et al, 2021). Moreover, when library visitors are crowded, users must queue to be able to search for books or scientific works.…”
