I have a table, eo_name_table, that has exactly 860 unique titles in it.
Each record also has a date field, eo_pub_date:

Hi Jerry,
I think the problem is that NULL is not less than or greater than your
prod_published date. So you probably have eo_pub_date set to NULL in 56
of your rows.
so for
eo_name_table.eo_pub_date prod.prod_published
or
eo_name_table.eo_pub_date = prod.prod_published

I've found yet another oddity with this situation. If I leave the date test
off of both JOINs they give the same number of rows, but they give me the
wrong number! Neither one of them gives me 860 rows returned. I must not
understand how a LEFT JOIN works.

Yes, that is the correct behavior of a LEFT JOIN. A left join keeps
all the record from the original/left table and will link up any
related data from the right table, but if there is no related data,
it sets it to NULL. If you want the join to act as a filter, the just
use regular JOIN.
I am attempting to left join several tables. This was working at one time
but has seemed to stop just recently. I have checked and installed the
lastest version of mysql via Debian Etch apt-get. I am running version
