The images within should be in the public domain. I was given the photos by colleagues from whom, if it came to that, I can request permissions. I can't immediately verify the false color T4 photo's provenance, so I removed it.

I've had to delete most these images:

• Image:Phage_lifecycle.gif
• Image:Lambda.jpg
• Image:T-_4_Phage.gif
• Image:Phage.gif

because of lack of source documentation for them. I hate doing that. If someone gives me a list of what exact images are still needed, I'll make an effort to find replacements we can fully document. The above four could in a snap be undeleted, too, if the source and copyright status can be verifiably documented. Stephen Ewen 15:39, 16 May 2007 (CDT)

Comments on first reading

• This article looks great and I am probably as good non-expert person to review it as anyone, I am going to quote a sentence that confuses me.

"One of the densest natural sources for phages and other viruses is sea water, where up to 107 phages per ml (or, at least, of virus-like particles)(Wommack & Colwell 2000). Whitman et al. (1998) argue that there are between 1030 and 1031 prokaryotic cells on our planet." ?????Nancy Sculerati 18:28, 16 May 2007 (CDT)

• Question: quoting the text:"Twort's work was interrupted by the onset of World War I, and when he returned to the Brown Institution, he spent the rest of his career trying to grow bacteriophages on artificial medium." Please include the punchline! He failed I take it because he didn't try to grow them in bacteria? Or what?Nancy Sculerati 18:35, 16 May 2007 (CDT)

• "Duckworth (1976) provides a historical account of the discovery of bacteriophages." This is a non-sequitor. Perhaps you should put his article or book under further reading and place this descriptor next to it. Nancy Sculerati 18:32, 16 May 2007 (CDT) Oh, I see- the next part is a summary of his writing? I don't know this history, if I did I would help you, but I suggest that you simply tell the story rather than give a list of events. Why are thses events important?

• Similarly, with the list of fmilies, the classification. I think what is needed here is an expalanation of how the taxonomy works, what features are used to classify the phages and why are these features important. Maybe it was a historical thing, I don't know, but some concepts need to be conveyed here. And then I suggest that either you make a catalog of the families that are presently in this list and link that to the article, or you make a table of this list that is not just a list but is arrayed in a manner that conveys the concept of how bacteriophages are classified.Nancy Sculerati 18:44, 16 May 2007 (CDT)
