This thesis attempts to suggest ways in which museums might better understand and make informed decisions about acquiring, preserving, and cataloguing photoblogs, which are an early twenty-first century photography practice. Photographers can now use the World Wide Web to show and share their images, because of the advent of digital cameras, camera phones, and cheap, open-source photo-blogging tools available to the general population. This thesis will help museums to better understand and be comfortable in acquiring digital artefacts, such as photoblogs, that will enrich their photographic collections for future generations. Acquisition tools and preservation methods are defined and discussed. The process of cataloguing photoblogs in current collections-management databases is not much different from cataloguing hard-copy photographs. The "People of Walmart" photoblog is used as an example and an illustration to clearly define the difficult technical jargon separating curatorial and collections management departments from information technology departments.
