IknoxvolsI, if the site you are referring to is High School Football Database (green background on the home page, multiple season scores listed on a school's home page), please read on; if not, ignore.
The HSFD site was my site; the Tennessee Prep Football Database is as well. I closed the HSFD site down a couple of years ago with the plan to transfer all the data to the TPFD site, and that is still the plan. Without getting into coding mumbo-jumbo, the HSFD site was a pain to update. I had to enter data manually, manually create every hyperlink, do mental/calculator math to update records, etc. It was a time-consuming and imperfect endeavor that just wore me, a "staff" of one, out. The idea behind the TPFD site was/is to have everything driven off of a true database, where scores only have to be entered once, hyperlinks are created automatically, and calculations are made by the database, eliminating human error in calculations.
The trouble with the transfer from HSFD to TPFD is that process, too, is time-consuming. I estimate it will take 500 man-hours to get all the data transferred, and as a hobby site (i.e., it's something I do in my spare time for no pay, 2-3 hours at a time a couple of days a week around my day job and family obligations), the math says it will take me several months to get all of the old HSFD data transferred. I wish it could be a quicker process, but frankly, there are plenty of consumers of such data out there but very few willing to do the research, learn coding, etc., and even fewer wanting to do it for free.
While I will agree that the TPFD site is not as informative currently, it will be eventually after the transfer. And while I will agree that the TPFD site is not as user-friendly as the HSFD site (the main complaint I get is having to scroll through season scores, where available, individually, versus seeing them all on one page), the school pages with complete histories are much more informative. For example, on the HSFD site, you could only see records versus opponents for certain schools but with no link to the history; on the TPFD site, there is a link to each opponent where one can see not only the records but also the actual game scores versus that opponent. As for other data on the site, if there is another individual site where one can find all 47 years of historical playoff records and scores, all-state players by school and source, bowl games, NFL draftees, etc. in one place, I haven't seen it.
There are other great score resources already mentioned in this thread, at least two of which have season score data and even more data associated with each (game dates, home/away, etc.). With that said, those sites go back only to the early-to-mid 2000s, and even those seasons have to be scrolled through individually (and the state history sites which I can consider the deepest in terms of data - Alabama and Georgia - also have scores available only through individual season scroll-throughs). For those schools for which I have full team histories - some provided by hardcore, loyal fans, but most provided by my own research after hundreds of hours at the State Archives poring through dozens of papers on microfiche, the scores go back well before the 2000s - in some cases, the early 1900s if not the 1800s in a few cases.
Long story short, I hope to make TPFD a deeper, more user-friendly site at some point. In the interim, if there is a school (or schools) for which you want to see the scores that you could see on the old HSFD site, I'll do what I can to accelerate the uploading of the scores to the site, as I still have every file from the old site.
