The main purpose of this paper is identifying the current situation of Iranian digital libraries in terms of interoperability abilities and proposing an interoperability solution for Iranian digital libraries. Analytical survey is used in this research. In fact, questionnaire and observation were used for collecting data about the current situation of Iranian digital library applications. The gathered data were analyzed by system analytical method in order to propose some practical suggestions to use in Iranian digital library applications. Iranian digital libraries mostly collect text files. They store data in SQL server and in relational database systems. The majority of Iranian digital libraries do not respect interoperability. They mostly use just Z39.50 clients so as to gather bibliographic data to use in cataloguing center. In fact, most of studied digital libraries do not offer extracting standard formats. Also, they do not make use of structural and administrative metadata format in their bibliographic data. The proposed model is based on harvesting model, OAI protocol and METS/MODS metadata standard. Findings indicated that Iranian digital libraries should be alert about the essence of interoperability. Using the proposed model would help them to be able to exchange their data in a more cost-efficient and cost-effective manner.

Traditional bibliometric indicators are only partially suitable for evaluating the scientific achievements of individual people. They are either not definitive or they are too complicated to use due to technical and methodological difficulties. There is still no definite evidence for the correlation between the citation rate (CPP) and the H-Index. In order to obtain a reliable assessment of what the relation is between the H-Index and the citation rate, we performed a study on 30 relevant scientists from the disciplines of particle physics and neurology. The foregoing discussions on the different correlations revealed that the form and degree of correlation do not just vary considerably between the individual comparisons but also amongst the disciplines. In both disciplines, the correlation between the citation rate CPP and the H-Index was relatively low. We also found varying degrees of correlation here.
