Right now it's on the front page at www.gbdb.info
But it won't be there for long, I just got a batch of Bachmann items I need to add and it's always the last three items that show on the front page.
But you can always use the regular or advanced search to find an item.
The direct link for the LGB database page is here:
The download link is then at the bottom right.
I converted this from a local webpage someone sent me years ago to a searchable pdf - hopefully that conversion worked properly.
I tried a few searches to test and those worked fine so I assume the whole LGB database was converted correctly.
