I haven't been keeping up so maybe this has been discussed but I have had the same problem and it seems to be the recent albums/CD's that have been encoded in AAC (the older ones were in MP3). If I look at the external disk that contains them, the ones that are in the iTunes library will be shown as "today" for the date modified and those that don't show up in the iTunes library even though they were ripped into it are in AAC format. They will be listed as last modified on the date they were ripped. I solve this by dragging the folder containing the album or artist back into iTunes and they then appear normally -- until sometime later when iTunes is restarted. Then they disappear again. Dragging the entire folder from wherever it's stored back to iTunes should solve Jim Wickman's problem though.
