SUVAG Polyclinic Library is a special library within the scientific institution. It has several types of collections: a Reference Collection, Doctoral and Master's Thesis Collection, a Periodical Collection and a Verbotonal Collection. The Reference Collection contains various encyclopaedias (general and field-specific), lexicons, dictionaries, handbooks and specialized materials such as atlases, all in printed form. Due to changes in access to such sources, the library has provided access to links to the most relevant online sources on its website. The Doctoral and Master's Thesis Collection brings together the thesis of employees of the SUVAG Polyclinic defended at the Universities of the Republic of Croatia. Since the SUVAG Polyclinic is scientific organization registered in the field of biomedicine and humanities, and in its research also deals with the field of social sciences (speech and language therapy), theses are most often defended at the Faculty of Medicine, the Faculty of Philosophy and the Faculty of Education and Rehabilitation Sciences of the University of Zagreb. It is important to note that from 2021. SUVAG Polyclinic is the scientific and teaching base of the University of Rijeka. For this reason, library materials and library collections can also be used by students. The purpose of the Doctoral and Master’s Thesis Collection is to collect, process, store and ensure the availability of dissertations and scientific master's theses of the institution's employees. The Periodical Collection includes a printed collection of old scientific journals mostly from the fields of biomedicine, speech and language therapy and phonetics and a collection of electronic journals subscribed to Croatian academic and scientific community by the Ministry of Science and Education. The Verbotonal Collection is an extremely valuable collection important for the history and current work of the institution: it contains publications related to the verbotonal theory and the verbotonal method founded by Petar Guberina, the founder of SUVAG Polyclinic. SUVAG Polyclinic is a unique health institution in the Republic of Croatia, but also a world center for the improvement, interpretation and dissemination of verbotonal theory and its application. In its work, in the diagnostic and rehabilitation processes, the SUVAG Polyclinic applies exactly that world-recognized method, which was established precisely at the SUVAG in Zagreb. The Verbotonal Collection contains: publications – monographs, proceedings and project documentation issued by the SUVAG Polyclinic related to the verbotonal method, scientific and professional journals which are issued by SUVAG Polyclinic, school magazines of the SUVAG Elementary School, which are a valuable indicator of the work of verbotonal teachers and rehabilitators etc. In the institution's repository in the DABAR system, there is a virtual collection that includes all issues of the internal professional journal Verbotonal conversations, which was published from 1995 to 2004. The SUVAG Polyclinic's repository also includes scientific and professional papers of SUVAG scientists and experts, most of which are related to the verbotonal method. Over time, the Verbotonal Collection has grown into a hybrid collection that gathers all scientific and professional productions on the verbotonal method. In addition, the publishing activity of the institution is related to the publication of monographs that are closely connected to verbotonal theory and the verbotonal method. Nowadays, e-sources occupy an increasingly important place in special libraries of hospitals and health institutions. By combining printed and e-sources of information, the SUVAG Polyclinic Library builds its collections through the acquisition of printed sources from its own sources and access to e-sources that are procured for scientific and academic institutions in the Republic of Croatia. Through procurement of e- sources by means of National and University Library, and as a scientific organization registered in the Register of Scientific Organizations, SUVAG Polyclinic has secured access to the most relevant international databases. By maintaining its collections, the SUVAG Polyclinic Library fulfills its fundamental role, which is to support the professional, scientific- teaching and research work of the institution's employees.
