I have over 50,000 photos. Events no longer show up. How do I create a new iPhoto folder like in the old days with iPhoto Manager?

Question

I have over 50,000 photos in the current iPhoto Library. I need to download 3,000 more from trip to Spain. Can/should I make a new iPhoto Library? How do I do that?

Answer 1

1) I had the same problem bedeviling me for over a month
(with the Apple Store people unable to figure out a solution!).
It turned out that the solution was exceedingly simple and easy:
http://apple.stackexchange.com/questions/18554/why-isnt-iphoto-11-showing-an-eve nt-present-in-the-library
I have no idea how it happened, but like Asbjornu, "I had managed to sort the events "manually" (View > Sort Events > Manually) which hid the newly created events in-between my rather large amount of existing events. Sorting by date (View > Sort Events > By Date + Descending) shows my new events first in the list as they should."
I left out a huge whoop when this (simple) command solved everything.
2) Yes, you can create another iPhoto library
http://support.apple.com/kb/PH2505?viewlocale=en_US
To create a new photo library:
                           Quit iPhoto.                       
                           Hold down the Option key as you open iPhoto.                       
                           In the window that appears, click Create New.                       
                           Type a name and choose a location to store the new photo library.                       
                           Click Save.
Afterwards, iPhoto will sometimes ask which library you want to open.
3) As far as the corrupted iPhoto is concerned,
trash or anything else, try rebuilding iPhoto (but
only after making a copy of your current iPhoto
library on an external disk, naturally).
Once the copy is made, close iPhoto, and
wait until you won't be using iPhoto or your computer for a long time
(like before you go to bed).  Close all other apps, or as many as possible,
and reopen iPhoto while holding down the Option and Command keys
at the same time.  Keep the buttons down until you get a page with a series
of half a dozen unmarked boxes or more, mark them ALL, launch rebuild,
and come back in the morning…
