1. Go to the NCBI nuccore database, at [https://www.ncbi.nlm.nih.gov/nuccore][1]
Copy and paste the search term:

    `(bacterial virus[Organism]) AND (3000:110000[sequence length]) NOT bacteria[Organism]`

You'll get 74583 results. 

2. Click on the link `send to` and click the check box `file`
It will then download. 

3. Check the file is in `fasta format` with ">" to start the ID.
4. If fasta format is absent return to the webpage and where it states `summary` switch that to `fasta text` 

I can't remember if point 4 is needed.

**Notes**
Seqence length, I'm guess all phages are between 3000 to 105 000 in length, this is to screen out partial sequences and to minimise  bacteria creeping in to the search. I don't quite understand how a phage can be 105 000bp in length, but you can twiddle these parameters to refine the search.
