I have Googled myself to death, but have been unable to find the following articles:

  • Breen, E., Monro, D., 1994. An evaluation of priority queues for mathematical morphology.
  • R. Beare and H. Talbot., 1999 Exact seeded region growing for image segmentation.

These articles are well known, important and often cited by others, but they seem to be impossible to find. Does anyone know where I could find these or maybe someone could point me in the right direction?

More generally,

What should I do when I cannot find an online copy of an article?

    $\begingroup$ @JukkaSuomela Thank you for your help. I don't want to seem ungrateful, I just want to point out that when the only way to read an article is to buy a book for 600 dollars and have it shipped 7000 km I am starting to think the authors don't want people to read their article. It's 2011. How about a downloadable PDF for 20 dollars? I should consider moving to a place with a decent library. Ok, I will stop complaining now. Thanks again for your help @JukkaSuomela $\endgroup$ Jun 13, 2011 at 11:31

    $\begingroup$ @MyName1234211: If you email the author of an article, they are usually quite happy to send you a copy or better yet, post a copy on their webpage. This was done all the time pre-Internet. $\endgroup$ Jun 13, 2011 at 12:21

    $\begingroup$ As Peter suggests, emailing the authors in computer science or mathematics usually results in either a PDF by return email, or the article being made available for download from a web page. Did you try this? $\endgroup$ Jun 16, 2011 at 17:33

    $\begingroup$ I generalized the question since the answer is general, and in future if we get a similar question we can close it as duplicate to this one. $\endgroup$

It seems that:

  • The first paper was published in Mathematical Morphology and Its Applications to Image Processing, J. Serra and P. Soille (Eds.), Kluwer 1994, ISBN 0-7923-3093-5 (a.k.a. Proc. 2nd International Symposium on Mathematical Morphology, ISMM 1994). Amazon link.

  • The second paper was published in Proc. DICTA 1999. Worldcat knows about the book. It seems that there are at least two Australian libraries that have it in their collections, so it should be possible to order copies of articles from them.

Fairly often, the interlibrary services of university libraries can provide copies of papers published in hard-to-find books and journals.

As Peter Shor suggested in comments, you can also try to contact the authors. Usually, authors will be happy to send you copies of their articles – after all, researchers write papers in order to make their results as widely known as possible.


If you have access to a library, look for a hardcopy of the journal or proceedings in their catalog. You might be surprised how much is available that way.

I have had good luck getting scanned copies of individual articles by making interlibrary loan requests (as suggested by others).
