`:Will Beback: Thanks for your response, and the useful information. But I need further clarification just to make sure I have got it right!  You wrote: ``Articles published in peer review journals are among the best sources available. The fact that an article is also posted on its author's website is irrelevant, but the citation should be to the journal and not to the website (though you can add a link to the website for the convenience of readers).``  My articles are not the paginated pdf versions (accessible by subscribers only). They are the final pre-publication versions (virtually identical to the published versions). Is it still okay to link to them? (Of course the journal reference would be given.)  Again, with reference to the two verbatim extracts from Stachel's books posted on my website: These articles contain no commentary by me, only Stachel's own words, but obviously the URLs are to my website. Of course in citing them I first cite the respective books by Stachel, noting the relevant pages. Is it alright to then add the URLs to the articles in question (enabling readers to see what Stachel wrote in the referenced pages), although the URLs are to my website?     `
