Final answer:
There are several reasons why search engines cannot find everything, including restricted access to library materials, non-digital sources, and limited library subscriptions. However, it is not true that the internet only prioritizes newer information.
Step-by-step explanation:
Search engines cannot find everything for several reasons. First, library materials may be restricted to student users, meaning that the content may not be accessible to search engines. Second, not all sources are in digital format, so search engines cannot index them. Third, some sources are not included in the library's digital subscriptions, which means they may not be available for search engine indexing.
Lastly, it is not true that the internet prioritizes newer information. While search engines may prioritize recent content to some extent, they also index and provide access to older information.
