I have converted the PG catalog into a mysql databases. There are some interesting anomalies.
For a first example, the following ebooks have no title:
| id |
+------+
| 1070 |
| 1071 |
| 1072 |
| 8817 |
| 9116 |
| 9117 |
| 9118 |
| 9119 |
| 9120 |
| 9121 |
| 9122 |
| 9123 |
| 9124 |
| 9125 |
| 9126 |
| 9127 |
| 9128 |
| 9129 |
| 9130 |
| 9131 |
| 9132 |
| 9133 |
| 9134 |
| 9135 |
| 9136 |
| 9137 |
| 9138 |
| 9139 |
| 9140 |
| 9141 |
| 9142 |
| 9144 |
+------+
This should allow us to answer some of the statistical type questions about PG etexts.
