Q. The sort by title function is acting strange. What's up?

For performance reasons the new catalogue loads only 300 records at a time. These records have not yet been sorted by title, but are still in the default relevance sort. These 300 titles will be the 300 most relevant titles.  So, these titles will be scattered randomly in the alphabet, some of which will be Z.  This sample is what is then sorted by title, so the last title in the sorted list will likely start with "Z".
