Here's some examples:
Xytex's Donor Catalogue from February 1998 (earliest archived)
California Cryobank's Donor Catalogue from February 1997 (earliest archived)
The Sperm Bank of California's Donor Catalogue from December 1998 (earliest archived)
Please let me know if you need any help using this resource. There are of course several obvious problems...anyone conceived before the Internet Age is out of luck (~pre-1997), and if a sperm bank's domain name has changed it may be more difficult to find their archives.
For anyone conceived from Xytex in the mid-to-late 1980s (and even potentially the early 1990s), I have FINALLY posted the list of donors from 1983-1984 I received from Xytex back in 2005 in an Excel file under the new section I just created "Old Donor Lists". Please feel free to check it out. Donors numbers that are in bold type have either the donor or offspring listed on a registry. If you think you may have been conceived from Xytex around this time and a bolded donor looks like a possible match I can put you in contact with that individual; or if know you were conceived from Xytex and would like to add your information, please email me. Not all donor numbers from that time are listed, so again, if you're a Xytex Baby from the 80s and would like to be added please let me know!
Also, if anyone has donor lists from anytime or any sperm bank - preferably those lists from before 1997, and would like to donate them (no pun intended) to my blog for others to access, please email me!! I'm slowly uploading these lists I have in PDFs to spreadsheets in Google Docs and publishing them, so please be patient!
