Pricing
The standard charge for papers and journal articles in the SPE eLibrary is USD 6.00 for SPE members and USD 20.00 for non-members. Some papers have been priced lower based on length or type. The eLibrary also includes some presentations and other documents that are free or a nominal cost. The price for a specific document is clearly identified on its preview page (the page you see when you click the title in the search results). eLibrary customers can elect to pay for their purchases in USD, GBP, or EUR.
