It's available, and it's yours! (I assume the page numbers you reference are the actual page numbers. The numbers I give in the Magic Window are the page numbers of the PDF, which counts the title page, etc. as pages.)
How would you like to be credited in the catalog? There are places for a catalog name (some use a nickname or forum name, some their real name) and a link to a personal web site or blog, if you have one. I recommend using whatever name you say (if any) when you say, "recorded by [your name]" as that's how listeners will look for you. (Keep in mind that prospective employers, classmates, enemies, etc. can also find you using the catalog name, so be cautious if privacy might be an issue.)
