Publishing your material
One of the purposes of copyright law is to enable creators to build on the work of others. In academic publishing (conference papers, textbooks, journal articles and the like), quoting from the work of others is a common practice.
There can, however, be a fine line between fair dealing and infringement of another author's copyright (or, for that matter, moral right). If it is a small amount of the other author's work, with substantial comment by yourself, the dealing may be fair. If you are using large amounts of the other author's text, with only minimal comment by you, this may render the dealing unfair.
If, however, you are using the quoted material merely to convey the same information as the author, but for a rival purpose, then that may not be fair dealing, but infringement.
You must also consider the amount of material you are using. Is it a small amount of the other author's work, with substantial comment by yourself, in which case the dealing may be fair, or is it large amounts of the other author's text, with only minimal comment by you, which may render the dealing unfair?
When you present a manuscript for publication, the publisher will require you to sign an undertaking that you have obtained all relevant permissions in relation to the use of copyrighted works in your own work. If you are uncertain as to whether your use of these works would meet the criteria for fair dealing, you should take steps to obtain a licence from the copyright owner to include those portions of their work in your own.
Copyright in published works is usually vested in the publisher, and an enquiry to the publisher is the best place to start. The publishing industry is volatile, with takeovers, mergers, and closures, so a web search for the publisher is probably a good place to start before writing for permissions to ensure that your request goes to the correct address.
Remember that such things as charts, diagrams, tables and maps are complete works, and you will need to request permission to reproduce them.
