In the article the author analyzes ownership and contribution notes notes published in Ukrainian catalogs of Cyrillic old printed editions, which are original and indigenous objects of local studies. Such notes contain information about contributions and contributors, their families' members, priests, landed estates' owners, about the other gifts, temples building and renovation, founders and beneficiaries, about military expeditions, battles, natural phenomena. Sometimes the notes include titles of several books given to a temple or list other religious items. Notes related to the history and local studies make it possible to reconstruct some episodes of the history of Ukrainian local territories, towns, villages, communities, churches and monasteries

Analysis of the creep behaviour of ferroelastic LaCoO3 and La0.8Ca0.2CoO3 perovskites at room and elevated temperatures is presented. It was found that the creep behaviour of the two LaCoO3-based compositions was determined by ferroelastic and non-ferroelastic creep strain components. Both the ferroelastic and non-ferroelastic creep strain components showed a strong dependence on bending stress. The ferroelastic creep depends on the coercive stress in LaCoO3 based perovskites, which in turn is a function of temperature. In addition, the ferroelastic creep strain has the same sign as the total strain of cobaltites upon loading, however, it has the opposite sign relative to the total strain upon unloading. Non-ferroelastic creep was negligibly small in both perovskites at low temperatures, however, its contribution toward the total creep increased significantly at elevated temperature. Non-ferroelastic creep strain has the same sign as the total strain both upon loading and upon unloading.
