The default value:

The byte count of this sparse array is less than this limit:

Therefore, the following summary box contains the complete expression:

This summary box can be copied and used as input:

Set $NotebookInlineStorageLimit to a small value:

The byte count of this sparse array is greater than this limit:

Therefore, the summary box does not store the expression, but provides an interface to do so:

This version of the summary box cannot be used as input by simply copying it:

Copying the summary and box and clicking the Store now button will create a usable input:

Restore the default value of $NotebookInlineStorageLimit:

Dataset respects $NotebookInlineStorageLimit:

Check the byte count of each expression:

Numerical functions such as InterpolatingFunction respect $NotebookInlineStorageLimit:

Check the byte count of each expression:

NearestFunction behaves similarly:

Array types that produce summary boxes respect $NotebookInlineStorageLimit:

Check the byte count of each expression:

Structured arrays behave similarly:

Statistical functions such as TimeSeries respect $NotebookInlineStorageLimit:

Check the byte count of each expression:

WeightedData behaves similarly:

GeoPosition respects $NotebookInlineStorageLimit:

Check the byte count of each expression:

Save space in notebooks by setting $NotebookInlineStorageLimit to zero:

Create a summary box, which will not contain the expression, and save a reference to the cell in c₁:

Restore the default value of $NotebookInlineStorageLimit:

Recreate the summary box for if, which now has the expression in it, and save a reference in c₂:

Output cell c₁ is about nine and a half kilobytes smaller than output cell c₂:

Save memory in a kernel session by setting $HistoryLength to zero:

Create a large summary box, which will not be saved in the notebook:

Because there is no reference to the output, the Store now button cannot work:

Create another summary box, but save the result in the variable data:

As long as data is not reset, the Store now button will continue to work:

Verify that the data was in fact larger than $NotebookInlineStorageLimit:

Restore the default values of $HistoryLength:

$NotebookInlineStorageLimit only affects summary boxes:

$OutputSizeLimit affects all outputs:
