What is a primary challenge for users of electronic virtual libraries?

The primary challenge for users of electronic virtual libraries hinges on the lack of uniform access procedures established for print libraries. In a traditional print library, users generally follow a familiar set of procedures to obtain materials, such as checking out books or accessing different sections of the library. However, electronic virtual libraries differ significantly in their interfaces, access protocols, and subscription models. This inconsistency can lead to confusion and difficulty for users who are accustomed to the more standardized processes found in physical libraries. As a result, users might struggle to navigate the myriad of platforms and systems, potentially hindering their ability to effectively find and utilize the resources they need.

In contrast, while the other options may represent certain limitations or challenges faced by electronic virtual libraries, they do not capture the overarching issue of access procedures that can broadly impact user experience. For instance, although a majority of elements being fee-based is a concern, many libraries offer access to a wealth of free resources as well. Similarly, the limitation to only textual information does not reflect the growth of multimedia resources available online, and restrictions on size and content offered may vary from one library to another, depending on their specific collections and assets.
