The article draws attention to the new possibilities of the research into the genre and thematic composition of Czech printed production of the 16th century, which are going to be offered by the Knihověda.cz portal in future. This portal virtually merges two databases of the national retrospective bibliography - Knihopis and Bibliografie cizojazyčných bohemikálních tisků 1501-1800 [The Bibliography of Foreign-Language Printed Bohemica 1501-1800]. It examines the genre composition of both Czech- and foreign-language printed production of the 16th century, which comprises a total of more than 4,000 units, and monitors the gradual development of the genres established in previous periods and the occurrence of entirely new genres. The aim of the paper is not a detailed analysis of the selected period but rather a basic overview of the genres and an indication of new research possibilities., Andrea Jelínková., Obsahuje anglické resumé a dvě textové přílohy, and Obsahuje bibliografické odkazy
The Yellow Sack Spider (Cheiracanthium punctorium) is a well-known species native to the Czech Republic. Several reports of its painful bite have gained much publicity. The species was considered to be very rare until the end of the 20th century. We provide information on the distribution, spread and ecology of this spider in the Czech Republic. Several cases of biting and its subsequent symptoms are described, and the toxicity of the spider is discussed. and Ondřej Košulič, Jan Korba, Jan Dolanský.
