For a general search use keywords. You can also make your search more specific; for example, to search for the article titled Adventure in a Bun use inverted commas; like this: "Adventure in a Bun". Or you can search for a particular author.
Once you have identified an article that you are looking for you can download it. Articles are available currently from Horizons issue No. 27 excluding the last 4 issues, which are available to IOL Members.
Articles going back to the first issues of "Adventure Education" in the 1980s are available only for photocopying or hard copy purchase.
