Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE attribute_definitions ( attribute_id number, attribute_name text, attribute_data_type text )
TABLE: CREATE TABLE catalog_structure ( catalog_level_number number, catalog_id number, catalog_level_name text )
TABLE: CREATE TABLE catalog_contents ( catalog_entry_id number, catalog_level_number number, parent_entry_id number, previous_entry_id number, next_entry_id number, catalog_entry_name text, product_stock_number text, price_in_dollars number, price_in_euros number, price_in_pounds number, capacity text, length text, height text, width text )
TABLE: CREATE TABLE catalogs ( catalog_id number, catalog_name text, catalog_publisher text, date_of_publication time, date_of_latest_revision time )
TABLE: CREATE TABLE catalog_contents_additional_attributes ( catalog_entry_id number, catalog_level_number number, attribute_id number, attribute_value text )

### Question ###
Which catalog content has the smallest capacity? Return the catalog entry name.

### Accurate SQL ###

SELECT catalog_entry_name FROM catalog_contents ORDER BY capacity LIMIT 1
