This article presents a number of conventional and modern techniques used for the examination of paper-based library materials, which were recently implemented in the Conservation and Restoration Laboratory at the National and University Library “St. Clement of Ohrid” - Skopje. The most important and widely used approaches for conducting the conservation research on many forms of works on paper with a historical value are outlined in terms of their applications and the kind of information on the constituent materials of paper artifacts that can be extracted. Special attention is paid to the conventional methods of micro-chemical analyses of paper artifacts. The sensitivity of the technique, various results obtained during the analysis with possible interferences, and the most compatible modern method are Summarised. A set of examples is provided for the demonstration of the capabilities of these methods for examination of paper and paper additives on manuscripts and old print books, some of which are part of the movable cultural heritage of the Republic of Macedonia.Članak predstavlja neke konvencionalne i suvremene tehnike koje se koriste u ispitivanju papirne knjižnične građe, a u novije ih vrijeme provodi Laboratorij za konzervaciju i restauraciju Nacionalne i sveučilišne knjižnice “Sv. Kliment Ohridski” - Skopje. Prikazani su najvažniji i najšire primijenjeni pristupi vođenju konzervatorskih istraživanja na raznim oblicima radova na papiru s povijesnom vrijednošću, u smislu njihove primjene i vrste informacija na tvorbenim materijalima papirnih artefakata koji se mogu izdvojiti. U radu su sažeti osjetljivost tehnika, različiti rezultati dobiveni tijekom analize s mogućim interferencijama i najsukladnije suvremene metode. Za prikaz mogućnosti ovih metoda u ispitivanju papira i papirnih aditiva na rukopisima i starim knjigama, od kojih su neke dio pokretne kulturne baštine Republike Makedonije, navodi se niz primjera
