I spent a good while reading the Digital Negative thread in the Alt process forum and also the thread started abotu Re-Defining APUG that sean started.
on about page 4 or so of the Redefining APUG thread there was mention of traditionally enlarging negatives for contact printing.
I attempted a search but dont know what keywords to use to bring of what has undoubtedly been discussed previously in the APUG community.
I have many a 4x5 negative that Id like to enlarge to 8x10 or 11x14 negatives to contact print and perhaps experiment with alternative processes. I read the digital negative thread but am more curious of the traditional manner of enlarging a negative and creating a negative from that negative and the means and ways to do this.

any help or links to past threads or other websites or books would be appreciated.
