The papers are kept in directories one for each year/month of the archive's operation. The year/month directories are specified in the format yymm. The first year/month of the bayes-an archive's operation was April 1995 (9504).
Multiple and mixed format requests are allowed, e.g., `list 9109 9110.abs macros new'.
The get command defaults to the current year/month so that, e.g., during 10/91 `get 1 2 5' or `get 01 2 005' will automatically prepend 9110's and necessary zeroes to result in `get 9110001 9110002 9110005'. Numbers too large for the current year/month have the previous year/month prepended. The get command also defaults to the current year, e.g. `get 9005' during 1991 gives `get 9109005', and months/numbers too large for the current year default to the previous year.
Multiple papers can be requested (e.g., `get 3 2.abs 9108001').
A single `get' command can be used to retrieve both papers and macros (e.g., `get 1 08005 2 55 harvmac.tex 9109058 2.abs').
