Checking for blanket permission
Some copyright owners give "blanket" permissions for their material to be used in certain ways. Information on these permissions is available in different places depending on the type of material.
For material from a journal article, check a recent issue of the journal, or the journal or publisher's website, to see whether there is a statement allowing the use you wish to make.
For material from a book, check the copyright statement (usually found on the back of the title page).
For material found on the internet, check any copyright statement. This will usually be a link from the homepage of the site, or under "About this site" or similar title. All material on the web is copyright, whether or not there is a copyright statement, but in some cases the copyright statement gives you permission to reproduce and distribute copies of the pages. There will often be conditions, such as a restriction to copying for educational use only, a requirement that the pages not be altered, or that certain acknowledgements must be included.
