Types of harvests

The main aim of the Webarchiv project is to implement a comprehensive solution in the field of archiving of the national web, i.e. bohemical online-born documents. That includes tools and methods for collecting, archiving and preserving web resources as well as providing long-term access to them. Both large-scale automated harvesting of the entire national web and selective archiving are being carried out, including thematic „event-based“ collections. At present these methods are tested and are a subject of further research. To run all operations in a routine way, two conditions must be met: long-term funding has to be provided and the current legal issues have to be solved (primarily the legal deposit legislation).[2]

Webarchiv have two collections of archived websites. One is available via online access; it's a limited dataset whose content is covered by agreements with its original publishers. Second collection can only be accessed in the Library. According to Czech copyright law online access to archived websites is based on agreement with website owner or on Creative Commons licence. Website without this agreement are blocked from the online archive and they are accessible only from the library terminals.[3]
