Here's a small suggestion that might help further organize Fakku's gigantic collection:
Take for example,
this entry (Tayu Tayu Chapter 1 by Yamatogawa-sensei). It's pretty obvious that it forms part of a whole book, the Tayu Tayu tankÅbon. You could add another link (besides View Online/Download/etc.) that would go something like "View Parent Book". This way, if there was another list of tankÅbon entries besides the individual chapter/manga entries, and said individual chapter/manga entries could be associated to said tankÅbon entries, it'd be a HUGE step in further organizing the collection of entries. It's basically the behavior of the "parent entry" label in -booru imageboards. There could be a new viewer page (like viewgroup.php or viewbook.php or whatever) that, when given a group/book ID, would load all the individual chapters that belong to said group/book, so people that want to get all the chapters in any given single book can do so more easily. ^^
<technobabble> And unless my DBA skills are rusting, it'd only require one additional table for the Group entries, and one additional field in the Manga entries table (assuming you have a single table for that xD) referencing the ID of the group each belongs to. =p </technobabble>
