Bookcase Claims

The bookcase

is an easily understood metaphor for the storage of numerous similar types of items of different specific knowledge (in this case virtual notebooks of different group's work) [Metaphor]
but additional sources of knowledge one would expect to find in a bookcase are not supported by the LiNC software (dictionary, etc)
but if a large number of student group notebooks exist it will be difficult to locate specific notebooks [Hick's Law]
