librrary database typos

ok, I know I've mentioned this one already, but for those of you who are interested in the typos group, the link is here:

and here's a sample of possible typos:
Adadem* ; Bpres* ; Distrub* ; Everday ; Intergrat* ;
Ot-the ; Portuges* ; Psued*

the * of course is for truncation, so that you retrieve all misspellings within the stem. Do you think databases do not have typos? yeah, right. ;-) Who do you think inputs those records? really smart robots?
