6. Information about licences and subscriptions for online content

Important : all users of this site should refer to the full terms and conditions for purchasing and using documents from this site. Click here to review this agreement.

All documents purchased through this site are issued in Adobe PDF format with a single user licence. Licences are issued to your user account , which is printed on the PDF (an email address).

If you require a multi user licence, or wish to purchase a document on behalf of someone else, you must contact the EI first, specifying your requirements to obtain the correct licence e:

Subscriptions are also available for most types of EI publications online.

Q. I have just purchased a PDF document. Can I send this file to my colleagues or print off copies for their use?

No, you cannot do this without prior consent from the EI. This would be in breach of the licence agreement you agreed to when purchasing the document, and contravenes Copyright Law. Any breach of the agreement will be investigated, as the EI treats seriously any infringement of the licence agreement or Copyright Law and may seek compensation from you if you are found to be in contravention.

In order to supply the document to others, please contact the EI about obtaining a multi-user licence for the document. Simply drop us a line, stating your needs, and that you’d like to be able to issue the document to a group of people. e:

Q. Are multi user licences expensive?

No, multi user licences work out to be an extremely cost effective and efficient way of making sure everybody has the information they need to hand. Additional licences are calculated at a fraction of the cost of the single user licence price. All you need to do is contact us with your requirements and we’ll customise the licence agreement to your needs – e: for further information

Q: What is the difference between a multi user licence and a subscription?

Multi-user licences are best for issuing single documents to a group of people.

Subscriptions are ideal if you tend to use a range of EI content on a regular basis, or wish to ensure that you have access to all the latest content as soon as it’s published. If this is the case, we recommend taking up a subscription.

Subscriptions are customised to your requirements and remove the need to purchase documents on an individual basis. You can specify a combination of documents, content areas or series as part of your subscription. Whether the subscription is just for you, your department, or your entire company, we’re able to provide you and your colleagues with access to all the information you need, when you need it. It’s cost effective and easy to use too!

For more information about subscriptions, contact the EI Publications team
