Construction products based on brick clay have been intensively used for the construction of buildings in the Republic of Serbia. The basic raw material for the manufacture of these products is brick clay, which is a natural mineral resource. However, the natural origin of clay provides no guarantees as to whether this group of construction products is eco-friendly. The production of baked clay construction products significantly affects the environment and cannot be neglected. The existing eco-labels used for this group of products are not uniform, in the world or in Serbia. The aim of this paper is to present a new approach to eco-labelling of construction products based on baked clay in the Republic of Serbia. Eco-labels can be given to products which meet certain authentic criteria. The criteria is based on an innovative set of 24 indicators which connect the production of construction products and the impact on the environment. Indicators were defined for the most commonly used construction products—facade brick, standard block and energy block. The research was conducted on leading producers of baked clay construction products in three regions—Northern Serbia, Western Serbia and South Pomoravlje. The obtained results indicate that one of the producers meets the criteria for innovative eco-labelling. The remaining two producers do not meet the requirements for the eco-label at the moment because there is not enough available data on the grounds of which certain indicators could be valued in a more complete manner. The data are unavailable to third parties because they are treated as a trade secret. Further research and an upgrade of the indicator set would create an opportunity to expand the number of baked clay construction products which could obtain the eco-label based on indicators.

Grkokatolička Križevačka biskupija čuva bogatu knjižnicu staru gotovo 400 godina koju su stvarali njezini biskupi i svećenici. U knjižnici su, osim crkvenih i teoloških knjiga, zastupljena djela iz svih ostalih područja znanosti. Knjige su pisane različitim svjetskim jezicima i pismima i tiskane u mnogim evropskim središtima tiskarstva. Zbirka knjiga broji 10.667 djela (9.858 svezaka), od kojih su 3 knjige iz 15. stoljeća (inkunabule), 68 iz 16. st., 325 iz 17. st., 3.996 iz 18. st., a ostale su iz 19. i 20. st. Tu je i vrijedna zbirka od 60-tak rukopisnih knjiga te zbirka periodike i sitnog tiska. Povijest knjižnice može se iščitati iz povijesti grkokatoličke biskupije koja je od osnivanja 1611. godine nekoliko puta mijenjala svoje sjedište. Prvih dvjestotinjak godina knjižnica se zajedno s bisku- pima selila (Marča, Pribić, Preseka, Gornji Tkalec), dok se od 1801., posljednjih dvjestotinjak godina nalazi u Križevcima. U 19. stoljeću biskupi su se u Križevcima uglavnom bavili preuređenjem prostora katedrale i biskupske rezidencije za potrebe grkokatolika, prilikom čega su pomno planirali i prostor za smještaj knjižnice. Prvi i za sada jedini poznati popis knjiga iz 19. st. nastaje 1856. godine, a popisuje 2519 djela, odnosno 1971 svezak knjiga. U 20. stoljeću slijede tri velika uređenja knjižnice: u doba Prvog i Drugog svjetskog rata, te uređenje započeto 1999. godine. Od godine 2007. knjižnica je otvorena za javnost. U njoj se priređuju izložbe popraćene vrijednim tiskanim katalozima knjiga. Uređenje knjižnice trebalo bi se nastaviti., Greek-Catholic bishopric houses a rich li- brary almost 400 years old. Its treasure has been collected by the bishops and priests. Apart from sacral and theological books there can be found works from other sciences written in different languages and printed in many European centres. The collection consists of 10.667 works in 9.858 volumes of which 3 are from the 15th century (incunabula), 68 from the 16th century, 325 from 17th century, 3.996 from 18th century and the rest from 19th and 20th centuries. There is also a valu- able collection of 60 manuscripts and assortment of periodicals and small printing materials. The history of the library can be read from the history of the very bishopric which since its establishment in 1611 changed its location a few times. Both the library and the bishopric moved from Marča to Pribić, Preseka, Gornji Tkalec to finally settle down in Križevci in 1801. In the 19th century the bishops were mainly concerned with the cathedral and residence recon- struction to meet the needs of Greek-Catholics, but they simultaneously planned the library space. First and up to now the only known catalogue dates from 1856 and lists 2519 works in1971 vol- umes. The 20th century saw 3 great restaurations: during the two world wars and the final one started in 1999. Since 2007 the library has been opened to public, it organizes expositions folllowed by fine printed catalogues. Its restauration should be continued.
