ACCESS TO ENERGY COPYRIGHT

The Access to Energy copyright is not intended to require readers to write, as many do, for permission to use the articles in helpful ways.

Articles in Access to Energy may be republished in other publications so long as they are not altered and they are attributed to Access to Energy. If you wish to edit an article, please obtain our approval.

Subscribers are welcome to make as many copies for distribution to others as they wish as long as these copies are not sold or used as substitutes for regular subscriptions. We print extra copies for use in advertising, so, if you wish to make a large number of duplicates of a particular issue, it may be worthwhile to write to us for copies.

Access to Energy is also used as source and background material by other publications with very large circulations that sometimes use parts of Access to Energy with or without attribution. Although we prefer mention, we are pleased to have these materials widely distributed.
