Abstract
Introduction. The purpose of this study is to explore the service quality of public libraries from user’s viewpoints using the critical incident technique (critical incident technique), e-mail inquiries, and unstructured interviews.
Methods. The researcher recruited eight participants, four female and four male who are the frequent public library users. Participants were asked to report positive and negative incidents or situations in relation to the services provided by their local public libraries, geographically located in Oregon, South, Dakota, Washington DC, Kansas, Vermont, and Missouri. This study utilized the conceptual themes of SERVQUAL, a model that has been used by many libraries for evaluating their public services. Data were collected and analysed from e-mail inquiries and unstructured interviews.
Results. Findings revealed that the positive incidents were slightly higher than the negative events. Also women library users had more positive experiences than men. Further investigations of this study are provided.
Conclusion. This study revealed that even though the participants reside in different states, their positive and negative incidents reveal similar situations. Further research would be expanded to a larger study population and/or compare other public library users outside the United States. Another possibility could be could be looking the size of the libraries and their serving population.


Introduction

Public libraries commonly use benchmark surveys and questionnaires to evaluate their operational services. These surveys typically were delivered quarterly with a set of questions and with a very limited number of open-ended questions. This direct approach study most likely are restricted to certain areas of library’s operational functions. In addition, library staff attitudes or behaviour and the facilities related concerns would also be less likely to be revealed. Therefore, instead of using the “traditional” approach, this study uses critical incident technique to gain insights of public library services. The critical incident technique relies upon on actual events which offer insights of the subjects. Past literature revealed that critical incident technique were primarily used to study health services related topics such as nursing care quality research (Kemppainen, 2000), health professional’s ethics (Arvidsson and Fridlund, 2005), and intensive care unit services (Buckley, et al., 1997). In the library and information study field, researchers used critical incident technique to user’s study such as information seeking behaviour (Urquharta, et al.,2003; Chaudhrya and Al-Sagheerb, 2011). These studies verified that critical incident technique is an effective research approach for user-centred studies.

This study evaluates the service quality of public libraries with the use of critical incident technique, gathering data through e-mail inquiries, and unstructured interviews. Eight frequent public library users were recruited in this study. A total of four women and four men volunteers participated in this study; their ages were ranging from 20 to 80 years old. Participants were interviewed and asked to report positive and negative incidents or situations in relation to the services provided by their local public libraries geographically located in Oregon, South, Dakota, Washington DC, Kansas, Vermont, and Missouri. The incidents are grouped, categorized, and then assessed with the use of the conceptual themes of SERVQUAL. The instrument consists of six dimensions: tangible, reliabilities, responsiveness, competence, courtesy, and security. The SERVQUAL has been used by many libraries for evaluating their public services (Parasuraman, Zeithaml and Berry, 1988).

Data collection

The process of data collection comprises two steps. First, the researcher sent out a message to participants, requesting them to record not more than five incidents in relation to both negative and positive examples of library services they received recently or in the past. All participants were given an explanation for this study and as well, were provided examples of standard critical incidents. The responses were collected and compiled within three days. Second, the incidents were categorized into various dimensions utilizing the SERVQUAL model.

The eight participants in this study were comprised of; a retired college professor, graduate students, civil servants, chemical researcher, university non-academic staff, and young parents. Of the eight participants that took part, there were 19 positive and 16 negative incidents. The details are displayed as in Table 1.

Classification of critical incidents

This SERVQUAL model contains twenty-two items with seven dimensions, which was developed by Parasuraman, Zeithaml, and Berry in 1988 for measuring the service quality from consumers' perspectives. Many libraries adopt this model to measure the quality of their services. The seven dimensions are tangibles, reliability, responsiveness, competence, courtesy, credibility, and security. In 2003, Satoh and Nagats extracted this model to five factors: Effect of service (personal), library as a place, reliability, collection and access, effect of service (organizational). In this study, the incidents are adapted from SERVQUAL model, as well as the Satoh and Nagats models, categorizing the incidents as the following domains:

After the classification by two coders and the examination of the validity of the inter-coding (the degree of the agreement between two coders is over 95%), the collected critical incidents were finally grouped in seven categories located in Table 2 with the related incidents collected from the participants.

Findings and discussions

Of 47 recorded incidents, library access issues accounted for more than one-third of all incidents, approximately 36.17% which represented 48% of the positive related critical incidents and 22.73% of the negative ones. Examples of positive incidents: "The library online catalogue was user-friendly, easy to locate the book that the user needed," "The computer section had plenty of computers and outlets for user tablets"and "the library items are always well-shelved in order and you can always find the items according to the call number." Examples of negative incidents: "The library stacks were separated based on Dewey Decimal Classification system, so there seems to be a lack of flow to the room/space," and "The parking lot drop off box was not conveniently located."

Based on these responses, the reliability of the public library is rated as negative. There is no positive incident recorded in this category. The competence category recorded five incidents, suggested that library staff possess the required skills and knowledge to provide adequate services.

The number of negative incidents in the courtesy category reveals that there is a lack of respect and consideration of library users. There were only 20% positive responses in this category. Examples of incidents that were given by participants are "someone talked very loudly in the library and library staff could not do anything about it," or "in the lobby of the library there was someone with a petition asking for a signature that dealt with an issue unrelated to the library."

The category of security covering the "library as a place, no risk" seems to be an area of problems: "The library was surrounded by homeless people who asked for money," "patron's personal information was found on a piece of scrap paper," and "library patron was continuously cussing in front of the terminal."

The data also suggested that women received more positive experience at the public libraries than men.

Conclusion

This study was conducted with eight participants who are regular users at their local public library. The data were collected either via e-mail inquiries or by face-to-face unstructured interviews (for those who live in Kansas City metropolitan area). Even though the participants reside in different states, their positive and negative incidents reveal similar situations.

This exploratory study demonstrates the strengths and weaknesses of public library services in general. However, the fact is that only twelve participants are in this study, the results thus cannot make a generalization yet serve as a platform for further investigations on this issue. Another weakness of this study is that both coders are experienced librarians which might generate bias in the validity of the categorization.

Several areas are suggested for further research. First, this study should be expanded to a larger study population and/or compare other public library users outside the United States. Secondly, to determine whether age would be a factor for receiving positive and/or negative services. Another possibility for further research could be looking the size of the libraries and their serving population.
