This study aims to describe case studies of two models, LibQUAL+ and a model based on the analytic hierarchy process (AHP), used to assess library service quality and compare the two assessment models.

First, an AHP-based evaluation model is set up to assess library service quality, following which the model is adapted to assess the service quality of Nanjing Agricultural University Library. Second, a modified LibQUAL+ model is created and implemented in the form of a questionnaire survey to assess the library service quality of the same library. Finally, the two assessment models are compared.

The results of the two case studies indicate that LibQUAL+ is suitable for assessing Chinese university libraries after modified, and the library AHP model is more suitable for comparing libraries in China between themselves.

This paper uses two methods for assessing library service quality; this should prove to be helpful for the librarians interested in assessing the service quality of Chinese university libraries.

The purpose of this paper is to establish a data mining model for performing sentiment analysis on open-ended qualitative LibQUAL+ comments, providing a further method for year-to-year comparison of user satisfaction, both of the library as a whole and individual topics.

A training set of 514 comments, selected at random from five LibQUAL+ survey responses, was manually reviewed and labeled as having a positive or negative sentiment. Using the open-source RapidMiner data mining platform, those comments provided the framework for creating library-specific positive and negative word vectors to power the sentiment analysis model. A further process was created to help isolate individual topics within the larger comments, allowing for more nuanced sentiment analysis.

Applied to LibQUAL+ comments for a Canadian mid-sized academic research library, the model suggested a fairly even distribution of positive and negative sentiment in overall comments. When filtering comments into affect of service, information control and library as place, the three dimensions’ relative polarity mirrored the results of the quantitative LibQUAL+ questions, with highest scores for affect of service and lowest for library as place.

The sentiment analysis model provides a complementary tool to the LibQUAL+ quantitative results, allowing for simple, time-efficient, year-to-year analysis of open-ended comments. Furthermore, the process provides the means to isolate specific topics based on specified keywords, allowing individual institutions to tailor results for more in-depth analysis.

To best account for library-specific terminology and phrasing, the sentiment model was created using LibQUAL+ open-ended comments as the foundation for the sentiment model’s classification process. The process also allows individual topics, chosen to meet individual library needs, to be isolated and independently analyzed, providing more precise examination.

The purpose of this paper is to assess the psychometric validity of the LibQUAL+® instrument in a developing country context in Bangladesh.

This study adopted a paper-version of the original LibQUAL 22 core-items to survey library users' perceptions of minimum, desired and perceived levels of service quality of university libraries in Bangladesh. The survey accumulated a total of 544 valid responses over a period of two weeks. The means and standard deviations for each service item were computed for the three service levels. The confirmatory factor analysis (CFA) was used to test the original three-factorial structure and to assess the psychometric validity of the LibQUAL instrument. A one-factor CFA and separate CFAs by gender and user group on perceived services were conducted to determine the original three-factor structure of LibQUAL scale. Exploratory factor analyses (EFAs) were also performed on the perceived scores to examine the potential factor structure of the scale. The descriptive statistics including EFAs and the CFA models were performed through IBM® SPSS® Statistics and IBM® SPSS® Amos, respectively.

The findings of this paper showed that all perceived services fell below the minimum scores. The confirmatory factor analyses found poor model fits for the original three-factor solution of the LibQUAL scale. The EFA results also showed no factorial structure similar to the original LibQUAL dimensions. The findings exhibited a low psychometric quality of LibQUAL in academic library settings in Bangladesh.

This study is the first of its kind to empirically examine the psychometric validity of the LibQUAL scale in a developing country perspective in Bangladesh.

The purpose of this paper is to measure service quality in a national library from users’ views, based on gap analysis model by using the LibQUAL+™ tools.

The study was done using a LibQUAL+™ survey. In this research, service quality has survived in three dimensions: Affect of Service, Information Control, and Library as Place in three levels – “minimum”, “perceived levels of services” and “desired level”. Statistical population of this research included all users (female and male) who use different parts of the National Library of Iran (NLAI) in the year 2010. Due to the high volume of population and time & budget restrictions, 332 people formed the sample size.

Findings showed that from users’ views, librarians could not meet minimum users’ expectations except in some cases. Library resource quality in perceived level of service is less than their expectations minimum. In other words, library resources could not meet minimum expectation and there are more gaps until desired level. Library as Place dimension has more quality than the two other dimensions, but NLAI place quality in perceived level is less than users’ expectation minimum. Of course there is a little gap with perceived level in this dimension.

The similarity in some results of LibQUAL+™ in academic libraries and national library implies that perhaps LibQUAL+™ tool is applicable for measuring library services in different type of libraries.

Using the LibQUAL+™ Survey has helped the national library in Iran to better serve its main user groups and showed that the translated and domesticated version of LibQUAL+™ can be reliably implemented in different type of libraries.

LibQUAL is a service‐quality assessment instrument developed by the Association of Research Libraries in partnership with Texas A&M University Library and has been used in numerous institutions. The purpose of this paper is to evaluate a Spanish version of the scale in terms of its structure, reliability, and validity.

Data were collected among students at a well‐known Mexican university. A total of 374 completed questionnaires were used in the analyses. Library service quality was measured using 22 items taken directly from the 2004 version of the LibQUAL scale. The back‐translation method was used to translate the original English version of LibQUAL into Spanish. Data were analysed using SPSS 16.0 and EQS 6.1 in the exploratory and confirmatory stages, respectively.

The study findings show that the Spanish version of the LibQUAL instrument actually consists of four dimensions: “affect of service”; “information access”; “personal control”; and “library as place”. The results support the reliability, convergent validity, discriminant validity, and nomological validity of the proposed Spanish version of the scale.

This is the first study to empirically evaluate and find support for the convergent, discriminant, and nomological validity of a Spanish version of the LibQUAL scale.

This paper aims to urge the new culture of assessment of the quality of library services among Iran academic libraries and to assess the overall services quality of libraries from the users' perspectives based on the LibQUAL model.

In this survey researchers used the LibQUAL model to assess service quality in the central libraries in engineering and technical governmental universities in Tehran city. For gathering data of libraries users, researchers used the LibQUAL questionnaire in a non‐electronic format and translated into Farsi.

It was found that library users were dissatisfied with their library building. But these libraries performed very well in the information control dimension. Furthermore, the examination of users' expectations showed that the proposition “Employees who are consistently courteous” was most important, and “Employees who instill confidence in users” had less importance.

Using the LibQUAL Survey has helped the university libraries in Iran to better serve their main user groups, and for the first time researchers used the non‐electronic format of LibQUAL questionnaire in the survey.

The purpose of this paper is to assess the quality of Iranian university libraries.

This first systematic review and meta-analysis were based on the PRISMA guidelines by searching in national and international databases from 2003 to January 2017 with standard Persian and English keywords. Data searching, extracting and quality appraising were completed by two researchers, independently. Any unexpected documents were assessed by a third expert researcher. Data were extracted in accordance with the “Strength of the Reporting of Observational Studies in Epidemiology” checklist after the final selection of appraised documents. Random effects size based on Cochrane test and I² were used for combining the obtained results from different studies together by considering the heterogeneity of studies.

Based on the meta-analysis conducted in 25 (6.42 percent) included studies, the total sample size was estimated. According to three dimensions of LibQUAL, findings of current information control, affect of service and the library as a place were estimated as 5.37 [CI95%: 5.02, 5.73], 6.91 [CI95%: 5.56, 6.26], and 5.46 percent [CI95%: 5.2, 5.73], respectively. Also, mean of service adequacy and superiority gap are equal to 0.07 [CI95%: −0.22, 0.36] and −2.06 [CI95%: −2.89, −1.23], respectively. There was a significant correlation between three dimensions of service quality and service superiority gap of LibQUAL and geographical regions of Iran (p<0.01). Also, a significant correlation was found between the gaps of services and three aspects of LibQUAL model and published years through a meta-regression test (p<0.01).

The results obtained from the present study showed that users are relatively satisfied with the quality of services provided by Iranian university libraries. An improvement in the quality of library services can promote the scientific level of universities.

The results of the present systematic review and meta-analysis study demonstrate a vital connection between primary research studies and decision-making for policymakers in Iranian university libraries to increase quality services.

The purpose of this paper is to evaluate the library service quality (LSQ) of University of Kashmir from the users’ perspectives based on the LibQUAL+ model approach.

The survey used the LibQUAL+ model to evaluate service quality (SQ) of Allama Iqbal Library (AIL), University of Kashmir, Srinagar (India). The data were collected from library users by administering the LibQUAL+ questionnaire in a printed format.

It has been revealed that AIL has succeeded in satisfying the minimum expectations of its users but could not meet the customers’ desired expectations that make them delighted. Library as Place (LP) and Information Control (IC) are the most satisfied dimensions of SQ of AIL, whereas Affect of Service (AS) is the least satisfied dimension. LP is the most desired dimension amongst LibQUAL+ dimensions. All LibQUAL+ items were found to be lying inside the zone of tolerance (ZoT). Further, “Library is secure and peaceful place for study, learning and research” (LP-21) was found as most important service item as per users’ desired expectations, while “Library staff shows dependability in handling users’ service problems” (AS-9) is marked as the least desired item.

Only a few studies have been carried out to evaluate the SQ of Indian university libraries as far as the LibQUAL+ model is concerned. Therefore, the findings of present survey will help to understand how far library has reached in satisfying users’ expectations as well as the areas or dimensions where it needs to improve.

The main aim of this paper is to examine the extent to which the major public university libraries in Bangladesh are meeting students' service expectations through analyzing LibQUAL+ core items.

The survey data were obtained from students using a paper version of the questionnaire consisting of LibQUAL+ core 22 service items at four top-ranked public universities in Bangladesh. Students rated the items on three service levels each using a nine-point scale: Minimum level, Desired level and Perceived Level. Descriptive statistics, i.e. mean and SD were obtained and service adequacy gap (SAG) scores between perceived and minimum levels were computed to see whether the libraries are meeting students' minimum expectation. Non-parametric Wilcoxon sign rank test was conducted to examine the differences between minimum and perceived scores. Finally, Mann–Whitney and Kruskal–Wallis tests were conducted to see the effect of students' demographic variables on their ratings on minimum and perceived scores.

The findings revealed that the service performances of major university libraries are lagging far behind from students' minimum expectation (minimum > perceived). There are significant differences between minimum and perceived scores. Significant differences are also found in students' gender, age and enrolment level concerning their ratings on minimum and perceived service levels.

The result of this study analyzes the service quality of major university libraries in Bangladesh. These findings can be used to identify the strengths and weaknesses of the library services.

LibQUAL+ has been used mostly in academic libraries in developed countries but this is for the first time a paper-version of the instrument was used in university libraries in Bangladesh.

The purpose of this paper is to outline three analytic tools utilized in the analysis and interpretation of LibQUAL+™ quantitative data.

D‐M scores, value rankings, and split‐file cross‐tabulations were used to assess the service items from the 2004 LibQUAL+™ quantitative data. The D‐M score is methodologically superior to other methods used in that it is a single score that takes into account all three LibQUAL+™ perception/expectation scores as dictated by the theoretical model LibQUAL+™ is based upon.

The paper finds that these tools provide a way to more easily utilize LibQUAL+™ results in taking actions and developing strategic plans designed to improve patrons' perceptions of service quality. These tools also allow for the continuous evaluation of implemented plans.

The paper discusses how these tools helped produce findings that were informative and in a format that decision makers could easily comprehend and utilize.

This paper outlines three approaches and offers practical recommendation of how to analyze and interpret LibQUAL+™ quantitative data as well as present findings to strategic stakeholders.
