Embodiments of the invention include techniques for storing and managing repositories of electronic presentation documents. Presentation storage repositories may be implemented in various storage systems including individual computer servers, distributed storage networks, cloud-based storage systems, and the like. Presentation search interfaces may support various searching and customization capabilities. Search interface and search engine components may be implemented to receive search requests from client devices, retrieve electronic presentation data from one or more storage repositories, and generate customized search results based on the retrieved electronic presentation data. Search and presentation capabilities may include storing user-specific selections of presentation cover slides, and then retrieving and/or generating user-specific thumbnails for search results interfaces. Additionally, presentation access and usage statistics may be tracked and stored within the storage repository and may be incorporated into the customized searching and presentation capabilities.
