6.1 Complete Dataset Overview
The original physical-dimensions field is available for 874215 records (66.3%) and missing for 443848 records. It contains 11447 unique non-missing values.
Gatherings information is available in the extracted original data for 109796 records (8.3%) and in the harmonized data for 420659 records (31.9%). Harmonization therefore added gatherings information for 310863 records. The original and harmonized variables contain 17 and 20 unique non-missing values, respectively.
Height information is available in the extracted original data for 758998 records (57.6%) and in the harmonized data for 868366 records (65.9%). Harmonization therefore added height information for 109368 records. The original and harmonized variables contain 744 and 744 unique non-missing values, respectively.
Width information is available in the extracted original data for 79753 records (6.1%) and in the harmonized data for 868366 records (65.9%). Harmonization therefore added width information for 788613 records. The original and harmonized variables contain 697 and 698 unique non-missing values, respectively.
6.2 Harmonization outcomes
Both height and width are available for 868366 records (65.9%), allowing document area to be calculated. Only one of these two measurements is available for 0 records (0%).
Document area was calculated for 868366 records (65.9%). Area remains unavailable for 449697 records because height, width, or both could not be reliably interpreted. These cases are listed in the entries where document surface could not be estimated. The harmonized area variable contains 4346 unique non-missing values.
The complete original physical-dimensions field contains 443848 missing values and 11447 unique non-missing values.
Original gatherings contain 1208267 missing values and 17 unique non-missing values. Harmonized gatherings contain 897404 missing values and 20 unique non-missing values.
Original width values contain 1238310 missing values and 697 unique non-missing values. Harmonized width values contain 449697 missing values and 698 unique non-missing values.
Original height values contain 559065 missing values and 744 unique non-missing values. Harmonized height values contain 449697 missing values and 744 unique non-missing values.
The harmonized oblong-format indicator classifies 1742 documents (0.1%) as oblong and 1316321 documents (99.9%) as not oblong.
Harmonized document area contains 449697 missing values and 4346 unique non-missing values. ## Document dimensions comparisons
Some dimension info is provided in the original raw data for altogether 874215 documents (66.3%) but could not be interpreted for 5821 documents, i.e. dimension info was successfully estimated for 99.3% of the documents where this field was not empty.
Document dimensions (area) info was obtained in the final preprocessed data for altogether 868366 documents (65.9%). For the remaining 449697 documents, critical dimension information was not available or could not be interpreted: List of entries where document surface could not be estimated

Document height info is originally available for 758998 documents (57.6%), and further estimated up to 868366 documents (65.9%) in the final preprocessed data.
Document width info is originally available for 79753 documents (6.1%), and further estimated up to 868366 documents (65.9%) in the final preprocessed data.
