In terms of nature, the present study is an applied research that, using a descriptive-correlation method. The study sample includes 140 employees of public libraries in Chaharmahal Bakhtiari Province. As well as descriptive statistics, the Kolmogorov-Smirnov test, Pearson correlation coefcient, and regression test were used to analyse the data. There is a positive and signifcant relationship between Calculus-Based Trust (CBT) and employees’ willingness to TKT. There is a positive and signifcant relationship between Knowledge-Based Trust (KBT) and employees’ W2S and apply TKT. There is a positive and signifcant correlation between Identity-Based Trust (IBT) and employees’ W2S and apply TK. The relationship between IBT and the desire to KS is stronger than the relationship between CBT and KBT. Therefore, IBT has a stronger efect than KBT and CBT on the tendency to KS. Employees in the IBT stage are more inclined to share and use TK than employees in the CBT and KBT stage. The TKT is an interactive process formed by the trust between the parties. The results of the current study show that OT has a positive and signifcant efect on the TKT of public library staf.

InTrOducTIOn Mutual trust is one of the factors afecting the willingness to share knowledge in public libraries 1-3 . Trust is formed in a context of intimacy and personal communication that facilitates the informal exchange of knowledge and increases the possibility of its sharing 4-5 . KS behavior of employees is directly or indirectly afected by various organisational factors 2,6 . One of the important factors in the formation of job relationships and the Tacit Knowledge Transfer (TKT) in the organisation is trust. Trust is defned as the belief and desire of individuals to do the work, description, and decisions of other people. The study sample includes 140 employees of public libraries in Chaharmahal Bakhtiari Province. The OT questionnaire Nguyen (2005) and the tacit Knowledge Sharing (KS) questionnaire Saparito (2000) were used. To investigate the efect of OT on TKT, this study has used the secure job relationship model Lewicki RJ, Bunker(1996) 7 and the TKT model Holste and Fields (2010) 8 . The results of this study are expected to provide an empirical basis for increasing productivity and synergy in public libraries. The low level of KS in these libraries poses many challenges and has many ancillary costs, including the need for in-service training, repeated task, lack of constructive social capital, or weakness in emerging factors in providing innovative and desirable services. So, this research encourages library managers to look for ways to improve the current state of the organisation. In addition, this study ofers a new approach to improving librarians’ knowledge-sharing behavior based on OT. 2. lITerATure revIew 2.1 Tacit Knowledge Transfer TK can be considered as a set of experiences, skills, work perspectives, and value and mental systems within the individual that cannot be expressed and is not stored in any database, but localised in the human mind and his activities 9 . TK is generally transferred through social interactions known as KS 10–12 . 2.2 Trust and Knowledge sharing Trust is one of the important variables in the use of KT
