The Directory of Library Codes enables British Library customers to convert into names and addresses the library codes they are given in response to location searches. It also indicates each library's supply and charging policies.
This information is specific to UK-registered customers of the British Library Document Supply services only and is unlikely to be of general interest to others. Please see the sections below for further information.

British Library Document Supply services
The British Library welcomes requests from any organisation. To order documents, you need to be a registered as a customer. Once you have registered, you will be sent full details of how to make best use of the service. To register your organisation use the link on the right.
Regional Library Systems
The Regional Library Systems are all constituted along similar lines, although membership subscriptions, and the range of services offered, vary considerably. We suggest that you visit the area's website, or contact the regional headquarters, to obtain current details.
The regional systems maintain union catalogues of the holdings of their member libraries, some being more comprehensive than others. In many cases they include the holdings of monographs, periodicals, newspapers, music, playsets, audio-visual works, etc. The Regional Library Systems also aim to facilitate the development of library services through cooperation. They work to improve the availability of resources within their areas, not just to exploit them.

The main purpose of the Directory of Library Codes is to enable customers of the British Library to convert location codes they are given into the names, addresses and contacts of those libraries that may be able to supply items that are not available from the British Library's collections. It also indicates, in coded form, each library's supply and charging policies.
PLEASE NOTIFY any errors, omissions or amendments to:
The British Library
Boston Spa, Wetherby
When confirming your order with the supplying library you will need to send them details of your British Library code and a unique reference number. The supplying library will claim the agreed charges for supplying the item to you by submitting a claim to the British Library. We will charge the agreed amount to your account and reimburse the supplying library. You will be charged a small administration fee by the British Library for facilitating the financial transaction on your behalf.
Supply and charging policies are indicated by up to three letters and are shown above the phone number (e.g. GL2, J4, SL3 ).

Category 'S' libraries
These include copyright deposit libraries and some former back-up libraries whose supply policies cannot be covered by F - L above.
|AB/N-1||Copyright deposit library|

Charging policy is at the time of going to press in line with that of British Library but may change.

Notes for suppliers and requesters
The British Library will process payments for third party interlending. The contract, however, remains between supplier and requester, and prices must be agreed between the parties; the British Library is only processing the payment on instruction from the supplier. The British Library charges a small administration fee to cover the costs of providing this service.
Ordering from location libraries
After agreeing or finding out the supplying library's charges (see Supply and charging policies), you can send your request to them by fax or email. You must quote your Customer Code and allocate a request reference number on each item you are requesting. At this stage you are giving a mandate to the supplier to instruct the British Library to debit your account with the agreed charge if the item is supplied. The supplying library then sends a claim to the British Library for any items they have supplied, listing charges, the requesting library's Customer Code and request reference number (please see section How to claim from the British Library for more details). We will then credit the supplier the total amount of the claim and debit individual requesting libraries accordingly. Requesters should keep a record of the reference number of supplied items so they can match them to the charges when they appear on their usage statement. We will add a small administration fee to each item charged to cover the cost of the service.
Supplying libraries should send their claims to the British Library at least once a month; requesting libraries will expect charges to be made promptly to their account.
Your claim must quote your own Customer Code and provide the following information for each satisfied request for which you are making a claim:
- requester's Customer Code
- request reference number given by requester
- whether the item was supplied as a loan or photocopy
- price, excluding VAT
So that we can process claims as efficiently as possible, we strongly recommend you provide a listing of all items supplied each week, rather than individual returns/forms for each item supplied. We reserve the right to return incomplete or incorrect claims.
We will credit your account with the total value of the claim, including VAT for photocopy supplies. If you quote a claim reference number for each claim, we will quote this on your monthly credit statement. If you are a regular net lender, i.e. your supplies to other libraries are regularly more than your use of the British Library, we can arrange for payments to be made to you in the form of a Bank Transfer (please clearly mark your claim).
British Library template for claims
An online claim form is available to help you send your claim. Claims made via the online form will usually be credited to your British Library account within 3 working days. Payments made by Bank transfer will take between 1 and 2 weeks.
