Yes, there are. ftp.cis.ufl.edu:/pub/perl/comp.lang.perl.*/monthly has an almost complete collection dating back to 12/89 (missing 08/91 through 12/93). They are kept as one large file for each month.
A more sophisticated query and retrieval mechanism is desirable. Preferably one that allows you to retrieve article using a fast-access indices, keyed on at least author, date, subject, thread (as in ``trn'') and probably keywords. Right now, the MH pick command works for this, but it is very slow to select on 18000 articles.
If you have, or know where I can find, the missing sections, please let firstname.lastname@example.org know.
