Can you not filter the transactions? On my Nationwide account statements I can select the type of entry, credit or debit, and then sub-divide into types of payments and the dates. That should reduce the amount of paper needed or, as has already been suggested, contact Barclays for the specific data.
I have Barclays online, there is a search facility where you put in the names of payees / payments you want to look for. So you could search for all transactions with 'ABC manufacturing' for example.
