   SELECT publisherID,count(*) FROM WLPbib GROUP BY publisherID;

That query is only acceptable if you want a list of all the publishers and
the books each of them produced.  If you only want the results for one
publisher

SELECT count(*) FROM WLPbib WHERE publisherID = '$idtoquery'

should be more than acceptable

Either way you may want to consider indexing this table if you have a fairly
large number of records or will be doing a fair number of these queries on a
regular basis
