Purpose: Relevance ranking algorithms rank retrieved documents based on the degrees of topical similarity (relevance) between search queries and documents. This paper aims to introduce a new relevance ranking method combining a probabilistic topic modeling algorithm with citation data. Data and Method: We applied this method to the iSearch corpus of c. 435,000 physics papers. We first ran the topic modeling algorithm on titles and summaries of all papers for 65 search queries and obtained the relevance ranking lists. We then used citation data with the existing relevance rankings, thereby incrementally refining the results. The outcome produced better relevance rankings with papers covering various aspects of the topic searched as well as the more marginal ones. Finally, we evaluated the retrieval performance of the proposed method. Findings: Findings suggest that the topic modeling algorithm might sometimes overlook the terms used in different contexts in the papers. However, the fusion of citation data to relevance ranking lists provides additional contextual information, thereby enriching the results further with various papers of higher relevance. Moreover, results can easily be re-ranked. Implications: We argue that once it is tested on dynamic corpora for computational load, robustness, replicability, and scalability, the proposed method can, in time, be used in both local and international information systems such as TR-Dizin, Web of Science, and Scopus. Originality: The proposed method is, as far as we know, the first one that shows that relevance rankings produced with a topic modeling algorithm can be incrementally refined using citation data.

This paper is written to commemorate my distinguished friend and colleague Sezen Tan who died in 26 th of August 2021. It emphasizes on her specific personal characteristics, in addition to her professional life in Hacettepe University Library, at first as a librarian and later as a library manager; it also emphasizes on her experience and accumulation in librarianship; her relationships with Hacettepe University Library staff and other professional librarians and non-professional library staff who work outside Hacettepe University Library. The paper concludes with her impact on myself and my feelings as a valuable colleague and as a close friend. [ABSTRACT FROM AUTHOR]

Purpose: The research-practice gap emphasizes the low participation rate of practitioners in research processes and the lack of collaboration between researchers and practitioners. This paper aims to determine the practitioner contribution to research, researcher-practitioner collaboration and, depending on these, whether there is a research-practice gap through two important Library and Information Science (LIS) journals in Turkey. Method: The data of the study were collected from peer-reviewed articles published in Turkish Librarianship and Information World journals. According to the article's author information, author profiles were created and categorized based on their profiles. These categories, which were determined as researchers, practitioners, students, and others, were analyzed and evaluated in the context of article authorship of practitioners and collaboration between researchers and practitioners. The research data of this study is open to access. Findings: Approximately 16% of the articles were published with the contribution of at least one practitioner. Approximately 10% of the total number of authors (845) were practitioners. The principal author groups of both journals are researchers in academic departments. Academic librarians were practitioners who published the most significant number of articles (10.53%). The contributions of practitioners working in libraries other than academic libraries to the literature were limited (2.98%). While the percentage of articles in which all researchers and practitioners collaborated was 9.74%, the percentage of articles in which LIS researchers and practitioners collaborated was 8.34%. The result of this study shows that KB researchers collaborated with academic librarians working at their universities in six publications (1.19%). In addition, it was found that practitioners collaborated in three (0.6%) publications and with researchers from different scientific fields in 10 publications (1.98%). Implications: The findings of this study show that there is a gap between research and practice in Turkey in terms of article authorship and collaboration. It is expected that this study, which deals with the subject based on evidence, to raise awareness about the participation of practitioners in research processes and the development of research collaborations. In addition, it is expected that the findings of this study will be extended by studies with different methods and scopes. Originality: In Turkey, there is a deficiency of current studies that directly address practitioner contribution and researcher-practitioner collaboration in publications based on evidence. This research aims to determine the existence of the gap between research and practice and fill the literature gap in our country. [ABSTRACT FROM AUTHOR]

Purpose: The study aims to determine the compatibility of the books with the principles of children's literature by examining the physical, internal structure, and illustration characteristics of the children's poetry books most borrowed from the Nilüfer Municipality Poetry Library and Misi Children's Library. Method: 98 books evaluated within the scope of the research with sampling were borrowed from the Children's Library and Poetry Library. A case study, one of the qualitative research methods, was used in the current work that collects the data through document analysis. Results: According to the findings obtained from the study, 95.9% of the books are medium size, 61.2% are stitched binding, 95.9% are straw paper, and 40.8% have 71 or more pages. When examining the page layout and grammar features, 42.9% of the books were written with single line spacing, 56.1% were written with 12 font size, 91.8% were left-justified, and punctuation marks were used in 55.1%. Regarding the illustrations placed in the books, 88.8% of the cover art is compatible with the content, 73.5% includes emotional expressions in the pictures, 44.9% has colored pictures, 74.5% keeps no pictures on each page, and 60.2%, places pictures and texts on the same page in a way complement each other. Considering the internal structure of the books, 34.7% tackle the theme of 'values' and 64.3% adopt a pastoral style. Conclusion: It has been found that the majority of children's poetry books borrowed from Nilüfer Municipality Poetry Library and Misi Children's Library have author promotion. The most borrowed children's poetry book belongs to Fazıl Hüsnü Dağlarca, and secondly to Mavisel Yener and Aytül Akal. Most of the books have illustrators and Mustafa Delioğlu is the the one who mostly took part in the illustrating process. The publisher that published the most children's poetry books was Yapı Kredi, followed by Can Child. It has been determined that the publication years of children's poetry books are primarily those of 2012 and 2008 and that the majority of the books are first editions. There is no age information in the majority of children's poetry books. Originality: Some studies examine the physical and content elements of children's books. However, studies on poetry books have not been much in the literature. The study is unique in examining the physical and content features of children's poetry books. It is thought that the study will draw attention to children's poetry books and their place in library collections. [ABSTRACT FROM AUTHOR]

Purpose: This paper aims to determine the problems of web citation accessibility in the Turkish Librarianship journal. Method: For this purpose, bibliographic records of the peer-reviewed studies published in the Turkish Librarianship journal between the years 2005 and 2020 were downloaded from the DergiPark archive and web citations were obtained according to the selected publication types. Then, usage rate of web citations, their access levels, the half-life of URLs, and accessibility of top-level domain names were identified and analyzed. Findings: It has been observed that web citations are frequently used in peer-reviewed articles in the Turkish Librarianship journal, and it has been understood that the usage trend has been increasing continuously in recent years. The average half-life of web citations in data is three years. In addition, the accessibility rate of web citations used in recent articles is higher than earlier ones. Implications: The findings indicate that there have been persistent decay and accessibility issues in the web citations of the Turkish Librarianship journal, and support policies encouraging the use of persistent identifiers should be developed to increase the accessibility of web citations. Originality: This is the first study in the Turkish academic literature to investigate the status of web citations of articles based in Turkey. [ABSTRACT FROM AUTHOR]
